• Continuous Sand Filter
  -Unique continuous back-washing system uses 50% raw water in place of filtered water
  -High efficiency in removing fine solids including colloidal particles
  -Easy maintenance thanks to an external sand air-lift system
  -Very low operational head loss allows gravity feed in many instances
  -Low capital and operating costs

• Multimedia and Sand Filter is used to reduce the level of suspended solids (turbidity) in process water. Suspended solids can consist of small particles such as silt, clay, grit, organic matter, larvae, zooplankton, algae and other microorganisms. The filtration degree of a multi-media filter depends heavily on the filter media and flow (velocity) through the filter.

• Carbon Filter is used to remove organic odour, colour and residual chlorine.
