Introduction

The JOWA BIO STP (Sewage Treatment plants) are designed for automatic operation
onboard ships in accordance with

IMO MEPC2(VI) and meets all the requirements in Marpol

73/78 annex IV.

The JOWA BIO STP is an aerated, submerged, fixed-film unit with a proprietary aeration
system that provides major advantages for the operators. The Bioreactor contains a cross-
fluted structured matrix, on which the degrading bacterial biomass adheres and rapidly grows.
The Bioreactor ensures maximum optimum biological treatment and the efficient aeration
system ensures that the Bioreactors produce no offensive odours.

1 System description

The JOWA BIO STP is an aerated, submerged, fixed-film unit with a proprietary aeration
system that provides major advantages for the operator.

The raw sewage is led to the pre-treatment chamber. In the pre-treatment chamber there is a
submerged macerating pump. The pump macerates the raw sewage to very small pieces
before it enters the bioreactor. The macerating pump is constantly running and when there is
no inlet water it collects water and sludge from the bottom of the bioreactor. The macerating
of the bottom sludge in the bioreactor prevents the bioreactor matrix from clogging.

The Bioreactor contains a polypropylene, cross-fluted structured matrix, as its media, on
which the degrading bacterial biomass adheres and rapidly grows. This matrix is
manufactured so that constant inter-mixing of the wastewater occurs in each vertical column
of the media, ensuring maximum contact between the effluent and the surfaces on which the
biomass is fixed. The wastewater is driven upwards by strategically placed aerators over
alternate columns of the matrix and it flows downwards in the adjacent column. In this way,
the effluent moves in a serpentine fashion through the whole of the Bioreactor to ensure the
maximum contact time and optimum biological treatment.

There are no moving parts inside the Bioreactor, and the self-cleaning aeration system, fed by
the air blower, provides:

(i)

The required amount of dissolved oxygen for the biomass to feed on and degrade
the waste.

(ii)

The motive force for the serpentine passage of the wastewater through the aeration
chamber with maximum contact with the degrading bacteria.

(iii)

The removal of solids from the Bioreactor without the need for back washing or
desludging procedures.

(iv)

The efficient aeration system also ensures that the Bioreactors produce no
offensive odours, unlike other biological treatment plants.

Solids are produced in all biological degradation processes due to the development of the
bacterial biomass by absorption of organic materials, nitrogen and phosphorus nutrients,
micronutrients and oxygen to perform the organic degradation to carbon dioxide and water.
During this process, which removes the organic contamination from the water, the biomass
film thickens on the matrix and eventually this slime layer becomes too deep for nutrients and
oxygen to penetrate right through it. At this stage, it stops producing sticky polysaccharides,
loses its adhesion to the plastic matrix, is detached by the sheering force of the air and water
in a sloughing process, and passes into the water stream which gravity flows out of the
Bioreactor. These fully digested, odouress, biological solids, or dead cells, is settled in the
settling chamber. The solids will be recycled back to the inlet and degraded like any other
organic material, providing that sufficient biodegradation capacity and residence time has
been built into the system.

For sewage treatment, the Bioreactors need no nutrient addition or pH correction and
chemicals are not required, hence there are no added costs or environmental problems
associated with the use of chemicals. Primary settlement of sewage is not needed as the
Bioreactor can take the complete waste, via pre-treatment chamber and the macerating pump,
removing the requirement for the handling of septic solids and their costly disposal. In

manual revB.doc

addition, the Bioreactor can accept all normal kitchen greases and fats in the wastewater and
successfully degrade them, removing the requirement for a grease trap and its associated
smells and costly emptying and disposal. The intensive bacterial activity that takes place in
the Bioreactor ensures that pathogenic bacteria, originally present in the sewage, are
competitively inhibited. Thus, a discharge to surface waters meets stringent quality standards.

Should it be required, ultra-violet light (UV) disinfection of the discharged waters and the
solids can be achieved in a compact flow-through unit to remove all microbiological
contamination. Where it is permitted, chlorine disinfection of the discharged waters is an
alternative, if required.

The Bioreactor based treatment systems is designed so that the discharged water is better in
quality than 50 mg/l BOD

(biochemical oxygen demand), 50 mg/l Suspended Solids and 250

faecal coliforms/100 ml.

Due to the high de-gradative power of the JOWA BIO STP, they are much smaller than
comparable biological degradation methods using suspended growth (rather than fixed-film)
systems. Such systems include activated sludge, extended aeration activated sludge, and
sequencing batch reactors (SBR). In these aerated systems, the biomass concentration cannot
be as high as in a fixed-film system, so the aeration volume has to be much larger. As a
consequence, the Bioreactor is much smaller than suspended growth systems and has a
smaller footprint. This makes the JOWA BIO STP very suitable for marine use. The
Bioreactors has a quick biological start period and is also non-sensitive to long shutdown
periods due to continuous sludge return.

In addition, because the Bioreactor is a submerged, fixed-film unit, the biomass is more stable
and able to tolerate both hydraulic and organic shock loadings better than the alternatives.
Low flows and loadings can, therefore, be accepted for extended periods. As a result, they are
not susceptible to having periodic failures of wastewater degradation and should continuously
achieve the required effluent consent levels.

The high stability of the Bioreactor means that it does not need regular attention. As there are
no sludge wasting and recycling procedures, which are required by suspended growth
systems, there is no need for a dedicated operator. It also has a low requirement for
maintenance and minimal spare parts usage.

Location on remote sites and unattended running is possible (optional), providing that there is
an electricity supply. All electromechanical equipment, including pumps and blowers, can be
supplied in duplex (optional), in duty and standby configuration, with automatic switchover
for even wear and, in the event of a failure of one of the dual units (optional), continuous
effluent treatment is assured.

4 Operations

For easy understanding please see

chapter 7, P&I Diagram and valve designation list

and

chapter 9, Electrical-wiring diagram

4.1 Start up

• Close valves V02 (Settling tank), V03 (Bioreactor), V50 (Bioreactor drain cock) and

V51 (Discharge chamber drain cock).

• Open valve V01 (Discharge) and V05 (UV bypass).
• Fill up the unit with water.
• Open all valves between the water outlet and the overboard.
• Turn the main switch in position “ON”.
• Turn the switch S0 in position start.
• Turn the switch S1 in position Manual.
• Turn the switch S2 to start the discharge pump and check that the motor has the

correct rotation.

• Turn the switch S3 to start the macerating pump and check that the motor has the

correct rotation.

• Turn the switch S4 and start the Air blower and check that the motor has the correct

rotation.

• Turn the switch S1 in position “AUTO”.

4.2 Normal operation

• The valves V02 (Settling tank), V03 (Bioreactor), V50 (Bioreactor drain cock) and

V51 (Discharge chamber drain cock) should be closed.

• The valves V01 (Discharge) and V05 (UV bypass) should be opened.
• All valves between the water outlet and the overboard must be open.
• The main switch in position “ON”.
• The switch S1 in position “AUTO”.

Under normal operation are the P01 (macerating pump) and P03 (air blower) running
constantly. The level switches control the pump P02 (discharge pump); the discharge pump
starts when LS02 (high level) is indicated and stops when LS01 (low level) is indicated.
The solenoid valve V30 opens once every hour for 2 min, when the valves opens it will start
the solids airlift from the settling tank back to bioreactor.

4.3 Normal operation with sterilisation of the discharge water
Follow the points above in chapter 5.2 and turn the switch S6 to “Chemical dosing” or “UV
sterilisation”

4.3.1 Start up of sterilisation with chemical dosing (optional)
The producer prior to the delivery adjusts the metering pump do not change the adjustments.

• Fill the plastic chemical container with the sterilisation chemical.
• Turn the switch S6 to the position “Chemical dosing”

The metering pump starts after every discharge when the level switch LS01 (low level) is
indicated. The metering pump adds sufficient amount of chemicals for sterilisation of a full
discharge chamber.

K:\1-NYA K\1.3-JOWA PROJEKT\Sewage unit\JOWA BIO STP\Manual\JOWA BIO STP 2
manual revB.doc

4.3.2 Start up of sterilisation with UV light (optional)
For detailed information regarding the operation of the UV please read the JOWA UV
manual, chapter 14. Note that this UV is not supplied with a solenoid valve.

• Open valves V04 UV inlet.
• Close valve V10 (UV bypass).
• Fill up the chamber via manually running of the discharge pump. De-air the UV via

the valve V07.

• Turn on the main power on the UV control cabinet.
• Turn the switch S6 on the main control cabinet to the position “UV sterilisation”.

Note! Never run the UV without water in the UV chamber, this can destroy the UV lamps.
4.4 Discharge of bioreactor and settling tank
Never discharge sewage and sludge when the ship is in harbour or in a restricted area. This
has to be done when the ship is in an unrestricted zone or to shore facilities via the Marpol
flange
To empty the bioreactor and the settling tank, proceed as follows:

• Set the switch S1 into “Manual”.
• Close valve V01 and if the unit is supplied with a UV close also VO4.
• Open valve V02 (settling tank), V03 (bioreactor tank) and V05.
• Turn the switch S4 to start the Discharge pump.
• Make the reverse of the points above before the start of filling up the plant.

The degradation process in this plant is done mostly on the submerged plastic matrix on
which the degrading bacterial biomass adheres and rapidly grows. When the bioreactor tank is
emptied, there is therefore no total loss of the degradation process. The plant will work
normal just after a few hours after it has been filled again.

4.5 Maintenance
4.5.1 Daily inspections

• Check that there are no alarm indications.

4.5.2 Weekly inspection

• Check the sludge return from the settling chamber to the inlet through the plastic hose.

The manufacturer pre set this airlift of the solids to once every hour for 2 minutes.

If there is still sludge in the water from the settling chamber, increase the

opening time with further 2 minutes of the solenoid valve V30, by changing
the time T2 in the PLC (Please check the PLC manual for information of how
to do this). The amount of sludge build up varies from time to time and from
ship to ship.

If there is no water or sludge the airlift pipe or hose can be clogged. Clean the

pipe and hose with fresh water and check the airlift again.

• Check if there is or have been any leakage, in pipe, hose or tank connections.
• If the plant is supplied with a chemical dosing system, check that the chemical tank

has a sufficient amount liquid. If liquid is to be added, ensure that;

Gloves and safety goggles are used.
If any spilling of chemicals, wash away by using water.

If chemicals come in contact with skin, follow instructions in Safety

and Health Data Sheets.

• If the plant has duplicate Pumps, Air blowers etc. Change the stand by pump to

service pump, to get balance the running time.

4.5.3 Monthly inspection

• When a UV steriliser is installed the chamber needs to be cleaned. Follow the steps in

the

UV Manual (chapter 5.1), chapter 14.

• Check the sludge content in the bioreactor.

Fill an Imhof conical glass 0 – 1000 ml with 1000 ml sample from the test

cock V50.

Leave the Imhof conical glass still for 30 minutes to let the sludge to settle.

After 30 minutes check the level of sludge content.

If the reading is below 500 ml the system is OK.

If the reading is above 500 ml there is too much of sludge in the bioreactor, the

bioreactor needs to be emptied next time the ship is in an unrestricted zone.
Follow the steps in chapter 5.4.

4.5.4 Annual inspection

Due to the build up of mineral sludge, the bioreactor needs to be emptied once every year.
This has to be done when the ship is in an unrestricted zone or to shore facilities via the
Marpol flange. Never discharge sludge when the ship is in harbour or in a restricted area.
Follow the steps in chapter 5.4.

• When the bioreactor and the settling chamber are empty following can be done:

Control the inner paint system.

Control the diffusers, unscrew them and check if the membrane is all right.

They should be tightly fitted in both ends of the pipe.

4.5.5 Sewage treatment plant accessories maintenance

All the STP accessories needs different maintenance, read about their requirements in the
enclosed manuals.

The over current relays are adjusted as follows:

Q01:

Macerating

pump

Q02:

Discharge

pump

Q03:

Air

blower

Procedure to reset: Open the control cabinet door and look visually at the Q01-Q03 and see
which of the over-current relay that is released, reset by push reset button. Check also if any
phase is missing by control the related terminals.

It could also be high level alarm in the unit, check what have caused the overflow in the
system.

If there is failure in specific units mounted on the skid. Consult the table of contents for each
unit’s specific manual in the binder.

1.0 Introduction

1.1 Welcome

Thank you for choosing an IWAKI ES Series metering pump. This instruction manual
deals with the correct installation, operation, maintenance and troubleshooting
procedures for the ES model metering pumps. Please read through it carefully to
ensure the optimum performance, safety and service of your pump.

1.2 Safety

and

Caution

Notes

Avoid areas where ambient temperature exceeds 40

C or falls below 0

C, or where

the pump or tubing would be exposed to direct sunlight.

Disconnect the pump from electrical power source before performing any
maintenance.

When working on or around a metering pump, always wear proper protective
clothing and equipment as recommended by the supplier of the liquid being pumped.

Depressurize the discharge tubing before disconnecting the tubing or performing any
maintenance on the pump.

1.3 Principle

Operation

The ES series electronic metering pump consists of a pump unit, a drive unit, and a
control unit. The drive unit is an electromagnetic solenoid. When the solenoid coil
is energized by the control unit the armature shaft moves forward due to the
magnetic force of the solenoid. The shaft is attached to a PTFE faced diaphragm
which is part of the pump unit. The diaphragm is forced into the pump head cavity
decreasing volume and increasing pressure which forces liquid in the pump head out
through the discharge check valves. When the solenoid coil is de-energized, a
spring returns the armature to its starting position. This action pulls the diaphragm
out of the head cavity increasing volume and decreasing pressure. Atmospheric
pressure then pushes liquid from the supply tank through the suction check valves to
refill the pump head.

2.0 Installation

2.1 Unpacking

Open the shipping carton and inspect contents for damage. If any items are
missing or damaged contact your local distributor to arrange for replacement.

2.2 Location

Choose a location for the pump which is clean, dry, close to an electrical outlet, and
allows convenient access to frequency control and tubing connections. Avoid areas
where ambient temperature exceeds 40

C or falls below 0

C, or where the pump or

tubing would be exposed to direct sunlight. Flooded suction (mounting the pump
below the level of liquid in the supply tank) is strongly recommended, especially
when pumping liquids that readily generate gas bubbles. Sodium hypochlorite and
hydrogen peroxide are common examples of such liquids. (See Figure 1.)

If flooded suction mounting is not possible, a shelf adjacent to (but not directly
above) the supply tank often works well. (See Figure 2.)
The supply tank or cover can also be used if it has provisions for mounting a pump.
(See Figure 3.) In any case, the total suction lift should not exceed (1.0 m).

2.0 Installation

2.3 Supply

tubing

The supply tubing run should be as short as possible. For flooded suction mounting,
install a shut-off valve with an appropriate tubing connector at the tank outlet. Cut a
length of tubing from the coil supplied and install between the shut-off valve and the
pump inlet fitting. For suction lift applications, install a foot valve on one end of
suction tubing and cut the tubing to a length such that the foot valve hangs vertically
about 25mm above the bottom of the tank. Avoid any loops in the tubing run that
could form a vapor trap. Running the tubing through a length of PVC pipe will help to
keep tubing straight.

2.4 Discharge

tubing

The discharge tubing run is less critical and can be any length required to reach the
application point. Avoid sharp bends or kinks in the tubing and protect the tubing
from sharp edges that could chafe or cut it. Install a check valve (optionally available)
at the injection point and connect the discharge tubing to the check valve.

Caution.

Any check valve using Hastelloy or other metal springs in liquid end is not
usable for chemicals (such as HCL) which corrode the Hastelloy or other
metal springs. Ask IWAKI for a special check valve for this application.

2.5 Electrical

Connect the pump power cord to a GROUNDED outlet supplying proper voltage.
Avoid branch circuits that also supply power to heavy machinery or other equipment
that could generate electrical interference.

3.0 Operation

Caution.

Do not operate the pump with a completely closed discharge-side
valve.
Operating the pump with the discharge-side valve fully closed may
lead to liquid leakage or pipe rupture. Make sure not to operate the
pump with the discharge-side valve closed.

Do not run the pump dry.
A pump, which has been run dry, may experience liquid leakage during
its liquid feeding operation. Make it a rule to run the pump after
supplying liquid inside the pump.
* Dry operation of the pump over a long time (longer than 30 minutes)
causes the pump to overheat and the pump unit (pump head, valve
guide etc.) to become deformed or the pump head attachment to
become loose, which may result in liquid leakage trouble.

Keep the pump head firmly assembled.
If the installation bolts on the pump head are loosened, liquid leakage
may result.
* Fasten the 4 hex. socket bolts tightly before starting the initial pump
operation. (The bolts may be loosened during storage or
transportation of the pump, depending upon the condition of each.)
* Fastening torque: 2.16 N• m
Tighten all the bolts fully by applying an equal amount of torque in a
diagonal order among the bolts.

3.1 Priming

Install the pump as described above. With the pump turned on, set frequency at
100%. If the pump is equipped with an air vent valve, open the knob 1/2 turn.
Liquid should move through the suction tubing and into the pump head. When
liquid starts running through the vent tubing, close the air vent knob and continue
with output adjustment described below. If the pump has no air vent valve,
disconnect the discharge tubing from the injection valve. When liquid enters the
discharge tubing at the pump head, set frequency to 0% to stop the pump and
reconnect the discharge tubing to the injection valve.

3.2 Adjustment

If less than full output is required, set the frequency to the approximate percentage
of maximum desired.

3.3 Calibration

If exact output calibration is required, first prime and adjust the pump as above.

Then connect a calibration column to the suction side of the pump. Turn the pump
on for one minute and read the amount of liquid pumped from the column. Adjust
the frequency up or down as necessary and check the output again. When the

desired output is reached, disconnect the calibration column and reconnect the
suction tubing. (See Figure 4.)

Figure 4

Calibration

4.0 Maintenance

Caution: Before working on the pump, disconnect the power
cord, depressurize the discharge tubing and drain or flush any
residual liquid for the pump head and valves.

4.1 Diaphragm

Replacement

Remove the power cord from the electrical outlet and disconnect the suction tubing,
discharge tubing, and air vent tubing. Remove the four head bolts with a 4mm or
5mm hex wrench. Unscrew the diaphragm and remove its retainer (small disk
behind the diaphragm). Install the new retainer and diaphragm on the shaft. Turn
the diaphragm clockwise until it bottoms on the shaft. Replace the pump head and
tighten the head bolts to a torque of 2.16 N-m.

4.2 Valve

Replacement

Remove the suction and discharge tubing. Remove the suction fitting, the valve
ass y (consists of 2 x valve ball, 2 x valve seat, 2 x valve guide, 1 x gasket & 1 x
o-ring). Install the new valve ass y. Be sure both valve seats are in the same
orientation. Refer to Figure 5, below. Tighten the suction fitting. Similarly remove
and replace the discharge valve ass y.

Valve Ass y Orientation

4.3 Tubing

Check ends of tubing for splits, cracks or thin spots. Examine the full length of
tubing for damage due to chafing, abrasion, stress cracks, excessive temperature or
exposure to ultraviolet light (direct sunlight or mercury vapor lamps). If any signs of
deterioration exist, replace the entire length of tubing. It is a good idea to replace
