The importance of coagulants in water treatment

Apr 11, 2024 | Environmental engineering, Integrated water management

In water treatment, coagulants play an essential role in the removal of suspended particles and dissolved solids. These chemical compounds promote floc formation, facilitating the agglomeration and subsequent removal of impurities through filtration and sedimentation processes.

Coagulants help to reduce water turbidity by promoting the coagulation of fine particles, thus improving the clarification of treated water. In addition, they can aid in the removal of organic and inorganic contaminants by promoting the capture and precipitation of these compounds.

The efficiency and cost-effectiveness of water treatment are enhanced by the proper use of coagulants, which can result in more efficient processes and reduced operating costs and chemical consumption. In summary, coagulants are a key tool in water treatment to ensure water quality and safety.

Our GRINCO QT coagulant is an innovative synthetic and organic product, patented for its ultra-high cationicity and different molecular weights. Its design is oriented to definitively replace traditional inorganic coagulants in the market. It offers an economically effective alternative to other organic coagulants, such as polidadmac or polyamine, in a wide range of applications, including effluent treatment in the paper, mining, oil, industrial and urban industries.

Advantages of QT coagulant:

  • Against inorganic coagulants:
  • Unaffected by changes in pH.
  • Requires less dosage.
  • Reduces residual iron content in treated water.
  • Improves dehydration capacity.

Against polyamines:

  • Reduces the formation of “Stickies” and “Pitch”.
  • Clarifies wastewater and deinking water.
  • Neutralizes ATC.

In front of polidadmac:

  • Can be used in flocculation, coagulation, decolorization and COD removal.
  • Acts as an algae eliminator.

Other uses in various markets:

  • COD removal in primary and secondary settling.
  • Adjuvant in sludge dewatering.
  • Color removal in the textile industry.
  • Water clarification in mining and petroleum.
  • Mineral thickening.
