Biological waste water treatment system for ships EVAC

Biological sewage treatment plants

Evac's new generation sewage treatment plants fulfil the IMO and US Coast Guard regulations, and the technical construction meets tight quality expectations. Biological sewage treatment solution is fully biological odourless process, which produces no toxic gases.

Biological sewage treatment plants have been designed to minimize technical problems and maximize total process reliability. They are suitable for vacuum and gravity toilet systems, but also for processing both black and grey water - or black water only.

Biological sewage treatment plant has two aeration chambers for high efficiency and optimized bio process. When discharging sludge, there is no risk to accidentally destroy the bio population.

Biological sewage treatment plant can be dimensioned according to the number of people onboard and system parameters. The unit is small in dimension when compared to bio processing capacity. It is also flexible as processing tanks can be split in special solutions.

Fully automatic operation means that only a little maintenance is needed. Simple construction results in low maintenance costs and low spare part consumption.
