Oily Water Treatment Systems
Jowa - Oil Discharge Monitor System
The requirements of the MARPOL Convention are that all oil tankers with a gross tonnage of 150 GRT and above must have an oil discharge monitoring and control system installed, incorporating an approved oil content meter, with a starting interlock and an automatic overboard valve control system. Oil Discharge Monitor consists of the following main parts:
Jowa - Oily Bilge Water Separator
Jowa Oily Water Separator is available in five different capacities; 0.5 m3/h, 1.0 m3/h, 2.5 m3/h, 5.0 m3/h and 10.0 m3/h. The skid is optimised so that the footprint of the 3SEP OWS is as small as possible. The 1m3/h model pictured has a footprint of only 950 x 760mm.
Jowa - Emulsion Breaking Unit
The unit separates up to 80% of the water in the emulsion. The treated water is then fed to an MEPC 107(49) approved bilge water separator. The residue is pumped to the concentrated sludge tank. The system is operating automatically, in a step-by-step program (PLC controlled). The working principle is flocculation.
JOWA - Emulsion Breaking Unit
JOWA Emulsion Breaking Unit is designed to break apart water in oily water emulsions. The unit separates up to 80% of the water in the emulsion. The treated water is then fed to an MEPC 107(49) approved filter type/bilge water separator. The residue is pumped to the concentrated sludge tank.
Monitoring and Control Systems
JOWA - 15ppm Bilge Alarm
The JOWA SEAGUARD 15ppm Bilge alarm is designed to monitor the effluent from a bilge water separator. The alarm is approved to IMO MEPC 107(49).
JOWA - Discharge Protection System
JOWA Discharge Protection System, DPS, has the advantage to monitor and control the discharge of Bilge water to prevent any accidental oil discharge. All data is logged and stored for later printout or down load. This gives the operator full control over the discharge. The DPS is available as a add on option to the JOWA 3SEP 15ppm bilge water separator. The unit functions together with the 3SEP’s control system and alarm. The entire DPS unit comes ready installed and pre-wired on the 3SEP’s control panel.
Water Handling Systems
Silver Ion Steriliser
Sterilizing drinking water with silver is a very old method and has been adopted frequently in many parts of the world. As a matter of fact, this method goes back to antiquity. Disinfection of water by dosing silver ions into water is completely harmless to human as well as animals. The amount of silver ions in the disinfected water is well below the maximum amount stated e.g. in the directives issued by the WHO. Silver ions do not change the taste, smell or colour of the water. Nor do they effect the physical and chemical properties of the water. The silver ions only kill off bacteria, germs, algae etc.
Dosing & Chlorinating Unit
The dosing/chlorinating unit is meant to dose a chemical into water. The chemicals can be chlorine for fresh water systems, corrosion inhibitors for main engine cooling water, pH adjustment of fresh water etc. The unit consists of a dosing pump, a control cabinet, an injection valve and a container for the chemical. The container is equipped with a low-level alarm which stops the pump in case chemical runs out, a suction valve and a manual agitator. All components are mounted on a stable steel frame for easy installation.
Fresh Water Treatment Systems
Jowa - RO Watermaker - Reverse Osmosis Watermaker
Reverse osmosis desalination is among the finest levels of filtration available. The RO membrane generally acts as a barrier to all dissolved salts and inorganic molecules. Water molecules, on the other hand, pass freely through the membrane creating a purified product stream. Rejection of dissolved salts is typically 98% depending on factors such as membrane type, feed composition, temperature, and system design. Capacity is 15T or 30T potable water per day. Continuously monitoring and automatically divert the product flow depending on salinity value. Full production with a temperature between 6-35C° and TDS 35 000ppm (salinity). Unique design with top quality HDMI interface. User friendly touch screen and prepared for communication to ECR/AIS via PROFIbus, CANbus, MODbus and more.
