Membrane bioreactor, biological wastewater treatment systems

Technical features

The Evac MBR  (membrane bioreactor) is an advanced wastewater treatment process that can treat all wastewater streams to current standards. Evac MBR treatment plants are certified to meet both the IMO MEPC 159(55) and the new IMO MEPC 227(64) with nutrient removal, and also have River Rhine certification and U.S. Coast Guard (USCG) type approval.

The Evac MBR is a biological sewage treatment plant that offers advanced black and gray wastewater treatment solutions. It directly replaces traditional biological units, and with its membrane technology it easily fulfills all current and imminent treatment requirements. In some cases, effluent from the unit can even be recycled for specific uses. It allows vessels to operate in environmentally sensitive areas, treating and discharging all wastewater generated by passengers and crew without threat to health or the environment. It is based on proven, very low-maintenance membrane bioreactor technology, which is capable of filtering out particles, even those as small as bacteria.

The compact footprint of the membrane bioreactor makes it ideal for retrofit to existing vessels, as well as for installation on new ships.
