A water treatment system constitutes the preliminary, primary, secondary and tertiary treatment stages through which water/wastewater is converted into potable water.

  • In the preliminary stage with the aid of bar screen/grit removal system very large particles such as plastic, paper, etc are removed. In the primary stage, the Total suspended solids are removed with the aid of clarifiers. The Biological Oxygen Demand and Chemical Oxygen demand are removed in the secondary stage with the aid of aeration process.
  • The tertiary system constitutes filters to remove the remaining total suspended solids that are left. Also it constitutes f Reverse Osmosis system to removed total dissolved solids and other ions. In the treated water tank, chlorination is done in order to disinfect and remove the bacteria present in the water.
