Sewage Treatment Plant

There several types of Sewage Treatment Plants available in EPE's product scope of supply:

Triton EC is an electrochemical sewage treatment plant, especially designed for treatment of both black (sewage) or the mixture of the black and grey water (wastewater from showers, kitchens, sinks, etc), onboard merchant ships, small yachts and cruise vessels. The system is designed to fulfil requirements of IMO MEPC 227(64) which specifies discharged waste water from sewage treatment plants. The plant operates in a continuous basis, is fully automatic in normal operation and requires low maintenance.

Capacities : 1,5-3,5-5-6,5-10-20-30-50-60-70m3/day

TRITON EVO is a reliable sewage treatment plant using an innovative Membrane Bioreactor (MBR) system for on board waste water treatment. A combination of both grey (galley/kitchen water) and black (sewage) wastewater reduces the overall energy consumption and maximizes the effluent quality in terms of COD, BOD, TSS and nitrogen removal. The plant can be continuously operated onboard of a wide range of vessels varying from cruise liners to cargo and military vessels.

Despite the fact that there aren't any limits for the nitrogen concentration in effluent, TRITON EVO biology removes nitrogen without the use of chemicals or excess activated sludge recirculation. The correct black/grey water ratio in combination with the activated sludge recirculation ratio provides sufficient nitrogen removal. This fact makes TRITON EVO suitable for offshore installations where the nitrogen concentration in effluent is an issue.
