The 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 IMO MEPC 107(49) approved filter type/bilge water separator such as the JOWA 3SEP. Use of the JOWA EBU combined with the JOWA 3SEP can reduce oil discharge levels to 2PPM or less.

 Fresh Water Treatment

Treatment of drinking water with silver is a very old method and is used in many parts of the world. This method goes back to the ancient Egyptians and beyond. Dosing water with Silver ions kills off bacteria, germs and algae, and controls their regrowth within the water storage and distribution system.  Since its introduction in 1970 thousands of ships have installed JOWA's Ag-S due to its simple design, high quality, and long service life.

 Fuel Handling

Part of the JOWA Fuel Management System, the Homogenizer reduces larger asphalt particles to less than 5 μm so they can be evenly blended and homogenized in the fuel without affecting fuel components prior to injection and combustion. The homogenizer efficiently treats incompatible fuel components and avoids instability or incompatibility problems during change over procedures prior to injection. The result is that the entire energy content in the fuel can be utilised, which makes for better economy.
