Designed to remove excess suspended solids (SS) and biological oxygen demand (BOD) from a wastewater treatment plant.

The sand filter meets stringent discharge consent standards above what is normally expected from a biological process or an industry standard clarifier.  

The sand filter will remove typically a minimum of 60% SS and 40% BOD dependent on particle size distribution. The waste backwash water is then returned to the plant for co-settlement and re-treatment.

Application

  • Commercial sewage  
  • Industrial wastewater
  • Water utilities and municipal wastewater
