Multimedia Filtration

Also referred to as total suspended solids or TSS, suspended matter consists of tiny insoluble particles in water that include grit, silt, clay, ferric iron and other precipitates. Suspended matter often adheres to the surface of RO membranes and interferes with the passage of water through the membrane which result in:

  • Membrane fouling, particularly the first elements of the first stage
  • Increased pressure drop, thereby causing lower flows
  • Greater pump discharge pressure used to overcome fouling, thereby leaving less pressure to drive the water through the membranes
  • Frequent cleanings and unplanned downtimes

Multimedia filters are ideal for all industries where the incoming water contains suspended solids. The filters are simply installed upstream from the RO system and remove the suspended matter from the feed water prior to it entering the RO system.Suspended matter in water is a common problem faced by a multitude of plants throughout the world. By using multimedia filters, the suspended solids are removed to ensure:

  • Maximum performance
  • Consistent quality and quantity of water
  • Minimal unscheduled downtimes
  • Protection of downstream equipment
  • Protection of RO membranes from fouling
