Anaerobic MBR

Anaerobic MBR was developed to treat high-strength (COD 5,000-250,000) and high-solids industrial wastewater streams. The unique combination of membrane filtration and anaerobic biological treatment results in significant advantages, including maximum COD (>99%) and TSS removal, lower disposal costs, methane-rich biogas and a smaller water footprint, as Anaerobic MBR allows the permeate to be reused.

Features

  • Cost reduction
    • Both operating and disposal costs
    • Small footprint
    • Increased sustainability
      • Superb effluent quality
      • Maximization of biogas production
      • (Potential) water reuse
      • Significant reduction of carbon footprint
    • Robust and easy to operate
    • Simple ATEX outline (due to closed membrane technology)
    • Odor-free

typical use

Anaerobic MBR uses a digester without oxygen. It provides biogas as a by-product, and uses inside-out tubular ultrafiltration membranes to produce high quality permeate.

Since Anaerobic MBR is capable of dealing with solids, fats and salts, this technology opens the door to treatment of high-strength and high-solids streams, including: 


  • Highly concentrated streams, such as in the dairy industry
  • Ethanol production facilities
        - Pot Ale, Spent Wash, Thin Stillage, Vinasse
  • Fat, Oil and Grease (FOG) containing streams
        - Ice cream and biodiesel
  • Breweries
  • Starch slurries
  • High COD chemical applications

scope

Anaerobic MBR combines membranes with anaerobic biological treatment. The Pentair scope consists of a scalable skid range optimized for high-strength streams, the X-Flow Compact 33V (a tubular 5.2 mm ultrafiltration membrane equipped with the patented Helix flux enhancement technology) plus engineering, commissioning and process optimization. 


Our unique services during start-up and commissioning ensure a flawlessly functioning MBR that will meet the expectations.

Fields of application

Developed for high-strength and high-solids (industrial) wastewater streams, Anaerobic MBR is at its best with a high COD (>7000 ppm) and starts with a daily COD load of approxiametely 3000 kg. With >98% COD removal, the effluent is of good quality and ready for reuse, while the biogas is a valuable green energy source. 
In case of lower COD, the Crossflow or Airlift MBR could be more suitable treatment technologies, even though both are operated aerobically. 

Based on your specific feedwater characteristics, our specialist can easily determine the optimum solution for your challenge.
