Coagulants for Industrial Waste Water Treatment

Presently conventional coagulants (i.e. salts of Aluminium or Iron) are used to precipitate dissolved solids and also to settle suspended matter in many effluent treatment plants. These pose problems of carry over finely divided flocs of aluminum hydroxide or ferric hydroxide into the clarified water and produce bulky sludge having a high water content. This increases the sludge handling and disposal costs.

Due to drop in pH on use of these coagulants, often further chemicals are needed to counter the effect.

EZO-FIX range of coagulants for industrial waste water treatment consists of 'nontoxic' cationic polymers which replace inorganic coagulants (viz Alum, PAC, Lime, Ferric salts) and also reduce cost of treatment.

Numerous other benefits include –

  • Reduction in sludge volume and desludge frequency.
  • Reduced sulphate/ chlorides in the treated effluent and negligible drop in pH of treated water.
  • Reduction in corrosion in coagulant addition pipeline and pump.
  • Savings in labour and electricity costs
