Product Description

Aiming at the weak point & the treatment methods of domestic sewage in villages & towns, Benenv developed an economic low energy consumption unit, the intelligent BN-MBR series of products, through technological innovation, scientific design & high end manufacturing. Many improvement & upgrades are applied to the new series, to achieve standardization, large production scale, maximum efficiency, lower power consumption & intelligent management. The units are stupendous, decorative & easily merged with the environment, gives people a visual enjoyment.

Application Areas

  • Purification and treatment of black andsmelly small rivers and surface water Small Scale decentralized domesticsewage treatment for villages,compounds and residential areas High quality discharge & reuse oftreated water

  • Small Scale decentralized domestic sewage treatment for villages,compounds and residential areas
  • High quality discharge & reuse of treated water

Features
