Bilge Separators * Sewage Treatment Plants * Vacuum Systems * UV-Sterilisation Fat Traps * Water Lifting & Holding * Oil-in-Water Monitoring Biological Sewage Treatment System: MODERN GERMAN MARITIME TECHNOLOGY FOR CLEAN OCEANS DVZ - JZR System Description The black and grey water will be send to the buffer by vacuum and gravity. The sewage from the galley will pass a fat trap before entering the buffer tank. The buffer tank has to buffer the pick loads of wastewater and homogenise it. There is a bottom aerator in the buffer tank for mixing and conditioning the waste water during the buffering...

The biological purified wastewater flows through a calming zone with guide tools and overflow weir to the intermediate tank. This tank works as a pump sump and buffer for the pump and as dry- and overflow protection for the STP system. For producing clean water, the biomass/ water selection will be done with a special BMSU-Membrane, which is designed and manufactured by DVZ-SERVICES GmbH. The used principle applied is the cross flow membrane filtration. The bleed pump forces a permanent high recirculation flow (bleed) inside the membrane tubes, and the Feed Pump feeds the biologically treated...
