Evac EcoTreat
Cost-effective biological treatment plant

The Evac EcoTreat biological wastewater treatment plant delivers the best of both worlds for owners of small vessels, with cost-effective treatment of black and gray water that meets and exceeds the latest environmental standards.

Evac EcoTreat is a biological system for the efficient treatment of black wastewater from toilets and urinals and gray wastewater from washbasins, sinks, galley, laundry and showers. Treating wastewater in this way completely eliminates the need for any chemicals or filters. The plant has been designed to make operation and maintenance as easy and cost effective as possible. Its compact footprint and low weight means it is suitable for smaller vessels where space restrictions may be tight.

Evac EcoTreat uses the submerged fixed-film bacteria principle with enchanced settling matrix for solids separation and UV light for final disinfection. Available in capacities from 2–11 m3/day, the plant is compatible with both gravity and vacuum-based wastewater collection systems.

Operating principle

Evac EcoTreat uses the submerged fixed-film bacteria principle. Black and gray water waste streams are fed to the inlet mixing tank either by gravity or by a vacuum pump. From there, the wastewater is transferred to the bioreactor tank by a macerating pump, which mixes gray and black water and cuts up solids. The wastewater is then driven through the matrix in the bioreactor tank by compressed air that is supplied by diffusers in the bottom of the tank. The air supplies oxygen and also enhances the biological process.

The treated water flows from the bioreactor tank into the settling tank by gravity, where it passes through the settling matrix. Before being transferred to the clean water tank, the water is exposed to an advanced UV light filter to eradicate all heat-resistant coli bacteria. Any organic or mineral sludge that accumulates in the settling tank is transferred back to the bioreactor tank for further treatment or removal from the system.
