3SEP – Oily Water Separator

The 3SEP OWS is a dual stage oily bilge water separation system utilizing differential specific gravity, coalescence plates and filtration to separate and remove free and emulsified oil. The unit is available in five different versions with the following 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 here has a footprint of only 950 x 760mm.


UV Steriliser

The unit is equipped with low pressure UV-lamps, powered by electronic high frequency ballasts, for highest efficiency and lowest power consumption. The sterilization process is microprocessor-controlled via data from the UV-sensor. In case of lamp failure the intelligent lamp monitoring system will promptly signal this occurrence, as well as the location of the broken lamp.


AG-S – 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.


Fresh Water Filter

Rehardening/pH-adjusting filter for potable water systems equipped with fresh water generators.
Sand filter to separate and remove solid particles in most water systems.

  • Calorifiers
  • Hydrophores
  • Filters for various applications
  • Pumps for pressurizing and hot water circulation
  • UV-sterilizer, silver ion sterilizer or chlorination
  • Control cabinet


Dosing and Chlorinating Unit

The dosing/chlorinating unit is meant to allow the controlled dosage of a chemical in water. The chemicals can be chlorine for fresh water systems, corrosion inhibitors for main engine cooling water, pH adjustment of fresh water etc.


JOWA DPS – Discharge Protection System

JOWA Discharge Protection System, DPS, has the advantage of monitoring and controlling the discharge of bilge water to prevent any accidental oil discharge. All data is logged and stored for later printout or download, giving the operator full control over the discharge process.
