Clewer’s patented water treatment system is a new kind of bio process, in which water is treated, sludge and nutrients are collected, and the treated water is either recycled or removed from the system. The patented water treatment process is also suitable for recirculating aquaculture systems.

Clewer’s biological treatment process is based on carrier technology, where micro-organism growth operate on the surface of the carrier. The blending of Clewer special bacteria and nutrient technology for bacteria forms a highly efficient water treatment system.

Patented RBBR technology

Clewer has patented the RBBR (rotating bed biofilm reactor) bioreactor and the related microbiology. One of the foundations of the bioreactor’s operating principle is utilizing centrifugal force in growing the biofilm. This system is an innovative process of water treatment, based on own bacteria and totally new innovating rotation technology.

More specifically, RBBR technology is a bioreactor which operates on the basis of bacteria on carriers specifically designed for different types of nutrients.

The bacteria are regular in nature. We produce the specific microbial population used in bioreactors ourselves. Our bacterial mix has been patented.

The advantages of RBBR

  • great treatment area – up to 90% fill
  • great oxygen transfer efficiency
  • cost efficient
  • low maintenance
  • small footprint, eco-friendly
  • scalable
