MBR is the heart of an advanced wastewater process and one of Evac’s Sustainability Spearhead Products. Including a nutrient removal unit in the system allows vessels to operate in environmentally sensitive areas, treating and discharging all wastewater generated by passengers and crew without threat to human health or the marine environment. 

Sustainability and operational efficiency have been the key drivers in the development process of the next-generation Evac MBR Mid-range. “The new, upgraded system comes with many beneficial features. In addition to the already occurring excellent treatment results, we have notably improved the system’s efficiency,” explains Alejandro Álvarez Camino, Product Line Manager of Evac’s wastewater treatment solutions. 

The latest version of Evac MBR has a robust design, and its fully automatic design has a low maintenance need. The tanks are all made of stainless steel; therefore, corrosion resistance is improved without the need for coating inside or outside the tank. Also, the membrane cleaning method has been improved, and sensors and pipe arrangements have been upgraded for safer and easier operation. 

The new upgraded design is compact and requires a 50% smaller footprint onboard the vessel than its predecessor. The mid-range MBR is ideal for navy and offshore installations, smaller passenger vessels with fewer wastewater streams onboard, and superyachts of all sizes. 

“Our ambition is to drive the development of our water and waste management technologies to perform at levels where our customers’ environmental impacts can be pushed down to zero. Dealing with waste requires a joint effort, and together with our customers and partners we can make it happen – a future with no waste,” Alejandro concludes.
