Press release 23 February: Evac’s new electrochemical wastewater treatment plant

Evac’s new electrochemical wastewater treatment plant

ORCA IV is Evac’s new electrochemical wastewater treatment plant designed to treat black and grey water aboard multiple vessel types, such as yachts and navy vessels, as well as on offshore platforms and other marine-type applications. Orca IV is a purely electrolytic wastewater treatment plant that fulfills the requirements of IMO MEPC 227 (64).

The compact and modular design of the ORCA IV makes it ideal for retrofitting to existing vessels, as well as for installation on new ships. It operates on a continuous basis, is fully automatic in normal operation, and requires low maintenance only once every 3 months. The hydraulic load for black and grey vacuum wastewater treatment ranges from 1500 to 70000 liters per day, depending on the model. The system does not require chemicals and there is no need for a separate sludge tank.

The ORCA IV has a low installation cost, offers high efficiency, and is suitable for small and narrow spaces. For more information, please contact us at
