Backwash Flat Membrane System

Backwash Flat Membrane System

Backwash Flat Membrane System involves suction filtration to form a layer of sludge caked on the flat membrane surface and, by means of backwashing, peels off and collects the cake.
The system can be used to reduce sludge and collect valuables from it.

Features

  • Without the use of flocculants, the system allows for sludge dewatering at a water content ranging between 30 and 70 wt% (*).
    * The moisture content of the recovered sludge and the filtration wire bundle will differ depending on the raw water properties.
  • The use of a membrane with a nominal pore size of 0.25μm controls SS in filtrate at or below 1 mg/L.

Applications

  • Collection of silicon abrasive powder
  • Collection of rare metal
  • Reduction of sludge
