Waste water treatment

Waste water treatment describes preparing water no longer needed or suitable for its most recent use for return to the water cycle with minimal environmental issues. Wastewater treatment is distinguished from water treatment by a general focus on disposal rather than use, although reuse is also possible, called water reclamation. Water reclamation implies avoidance of disposal by use of treated wastewater for various purposes. Treatment means removing impurities from water being treated; and some methods of treatment are applicable to both water and wastewater. FWT products can be used in the following areas with respect to the wastewater treatment techniques:

  • Polymers-Anionic and Cationic for Phosphate removal, coagulation and filtration;
  • Caustic Soda for metals removal, pH control and Cyanide removal;
  • Ferric Chloride and Alum for coagulation;
  • Lime slurries for pH control (corrosion) and coagulation;
  • Sodium Hypochlorite for disinfection; Phosphate removal;
  • Activated carbon slurries for odour and colour control
