New Generation Wastewater Treatment Plant With 99% Result


Evac has developed a new, mid-size version of the Evac Membrane Bioreactor (MBR) wastewater treatment plant for various vessel types. The novel Evac MBR Mid-range treats all wastewater streams to current standards – and beyond, says an article published in Newscision.

Best possible treatment

Evac MBR offers the best possible treatment results by filtering up to 99% of microplastic particles and including option for nutrients removal. The effluent quality is so good that the treated water can be reused or further processed onboard the vessel.  

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. 

Upgrade for safe and easy operation

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. 

A future with no waste

“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.

  1. Untreated sewage can pollute rivers, lakes and oceans, harming aquatic life and making the water unsafe for humans. I advise you to learn more about treatment systems from BIOMAX here . Wastewater treatment is necessary to protect the environment and public health. By removing contaminants from wastewater, we can reduce the risk of water contamination and the spread of waterborne diseases. This in turn helps protect our natural resources and preserve fragile ecosystems that depend on clean water.
