Waste water treatment system for yachts and ships RWO GmbH
MEMROD

The MEMROD®-Process is a bioreactor with high biomass concentration. Submerged membrane filtration guarantees a pure effluent without any suspended solids and without the requirement of disinfection.

MEMROD® permits both black and grey wastewater as well as galley wastewater to be treated in a single reactor system. The effluent levels are better than the requirements of the International Maritime Organisation (MARPOL, Annex IV) and both the future
standards MEPC.159 (55) and the USCG/Alaska-Rules.
