Chemical-free treatment. No monthly chemical bill.

Most treatment plants depend on daily dosing of coagulants, polymers, lime and acid, and the bill arrives every month for the life of the plant. Ours are designed to run without it wherever your effluent allows.

  • No daily dosingNo dosing pumps to run, check or adjust.
  • Nothing to buy or storeNo coagulants, polymers, acids or lime on your site.
  • No chemical sludgeOnly pure biological sludge, dried on simple sludge beds.
  • Sludge you can reuseDried biological sludge can be used as manure.
  • Near-zero disposal costNo chemical sludge to transport and pay to get rid of.
  • No pungent smellNone of the smell chemical sludge leaves behind.

A few effluents need a chemical step: metal removal in electroplating and colour removal in dyeing. We tell you upfront and keep it to that one stage.
