Pile Cloth Media Filtration

«During filtration the individual pile fibres lie flat to form a dense and effective barrier to suspended solids.»

The pile fibres used in this process are comparable in their structure to an animal fur. During filtration the individual pile fibres lie flat to form a dense and effective barrier to suspended solids. During backwash, the fibers briefly stand vertically inside the suction header, so that the retained solids are easily removed.

By using the filtration capabilities of the very fine fibres in the unique pile cloth media, very high particle separation efficiencies are achieved while operating at high hydraulic loading rates, handling high solids loading events and producing low washwater volumes.

Many Areas of Application

  • Retention of residual solids from secondary clarifier caused by bulking sludge, scum formation and / or hydraulic overload
  • Separation of the excess sludge after rotating biological contactors, trickling filters and other biofilm processes instead of conventional secondary clarifier
  • Reduction of the phosphorus content in the effluent of existing or new wastewater treatment plants in combination with coagulation and flocculation
  • Reduction of micro-pollutants (or trace elements) in combination with powdered activated carbon (PAC)
  • Solids removal by physical/chemical treatment
  • Pre-filtration to nitrification system biofilms
  • Pre-filtration with UV disinfection
  • Pre-filtration to membrane filtration, MF/UF
  • Pre-filtration in drinking water from surface water
  • Road wastewater treatment (technical SABA)
  • Combined sewer overflows
  • Operating water treatment
  • Circulation water
  • Upgrading of sewage treatment pond
  • etc.
