Waste water treatment system for ships Aco marine
ACO MARIPUR

Characteristics and advantages
ACO Maripur represents the highest possible standard of wastewater treatment plant currently available to the marine market. The ACO Maripur, with low-pressure micro-filtration units, offers the following advantages:
%u2022 Compact process due to high sludge concentration in the reactor. This equates to a greatly reduced footprint allowing more effective use of limited space on board ships. Power requirements for even the largest 200-man units are extremely low compared to comparable sidestream crossflow systems.
%u2022 Removal rates are significantly better than those required by current legislation. This gives operators the confidence that they will meet all likely future legislation and may even be allowed to discharge waste water in areas where this is currently prohibited (zero-emission areas).
%u2022 No need for an environmentally harmful and expensive secondary treatment stage for disinfection. Secondary chlorination or UV sterilisation, indispensable in conventional systems, are not necessary for biological membrane systems which form a physical barrier to the activated sludge, suspended solids, bacteria and even viruses.
%u2022 The application of micro-filtration units instead of conventional settlement means the ACO Maripur is unaffected by ships movement.
%u2022 Simple, automated process, requires minimal operator intervention and training.
%u2022 Able to treat both black and grey water (including laundry and galley water) in one reactor. This reduces the risk of further expense should incoming legislation require total treatment.
