Coagulants and Flocculants

Coagulation is the process by which colloidal particles are destabilized in order to form flocs through the process of flocculation, enabling them to be separated from the water. Through the application of the applicable product, destabilization is achieved. 

Flocculation is then the next step whereby individual destabilized colloidal particles are aided to collide with one another, allowing them to coagulate in order to form larger floc particles in the water. Such floc particles can then be removed via filtration or sludge pumps.


Barfloc™ FP Organic Coagulants

The range of Barfloc™ FP organic coagulants are a novel and superior approach to sludge reduction.

An efficacious alternative to organic salts, the product technology is based on a poly-quaternary ammonium compound. It can partially or totally replace the use of conventional products in the different stages of waste water treatment where coagulation is needed.

Working synergistically with inorganic salts, the range has shown high efficiency, and FeCl3 or PAC usage can be significantly reduced through the addition of Barfloc™ FP products. Due to this, an improved economic profile can be achieved in the following areas:

  • COD removal on primary and secondary sedimentation
  • Sludge dewatering
  • Colour removal in textile industry
  • Phosphorous removal in combination with inorganic salts 

Product tests have revealed a dose rate reduction of inorganic salts of up to 50%, positively assisting with the discharge profile of the effluent. A reduction of up to 30% of the sludge volume produced by inorganic salt compounds can also potentially be observed.

Other benefits include:

  • A low alkaline form, therefore limited consumption of the alkalinity of the effluent, and pH adjustment is therefore not needed
  • High cationic charge, allowing user to save on amount of product required
  • Good synergistic effect with acid inorganic salts for phosphorous in solution in biological stage
  • Improved settling speed when compared to inorganic coagulants due to the chemistry and the conformation of the molecule, allowing two kinds of bonds to take place (neutralization of electrical charges and Van Der Walls bonds)
  • When compared to ferric chloride, less hazardous exposure dangers for operators
  • Effective over a wide range of pH levels
  • Does not cause stains or odours
  • Does not affect the conductivity of the water
  • Product is applied via standard metering pumps (for Barfloc™ FP2, FP3 and FP5), reinforced pumps for Barfloc™ FP4 (as quite viscous)


  • Application: Industrial, municipal waste water, specifically ideal for pulp and paper industry
  • Easy to dose liquid form necessitating only conventional dosing pumps
  • Product packaging size: 25kg polycan
