Polymers - Water Treatment Flocculation

Polymer flocculation Water Treatment - Chemiphase a water treatment specialist have an extensive range of high performance polymer water treatment chemicals includes both liquid/emulsion and dry/powder polymer products. These advanced polymer water treatment chemicals have been developed for use in a range of demanding industrial and municipal applications involving process water treatment, wastewater and effluent treatment.

Chemiphase's range of advanced polymer flocculation water treatment chemicals includes high, medium and low molecular weight cationic and anionic polymers in both liquid/emulsion and dry/powder forms.  For more information on our flocculation polymers please contact us.

Polymers play a crucial role in water treatment, particularly in the process of flocculation. Flocculation is a vital step in the removal of suspended particles from water, making it clearer and more suitable for various applications, including drinking water, industrial processes, and wastewater treatment. Polymers used in water treatment for flocculation are known as flocculants or coagulant aids, and they enhance the efficiency of the coagulation process.

The flocculation process involves the addition of chemicals, typically coagulants such as aluminum sulfate (alum) or ferric chloride, to the water. These coagulants destabilize and neutralize the charges on the suspended particles, causing them to clump together and form larger aggregates called flocs. However, the flocs formed by coagulants are often relatively weak and may not settle or separate from the water effectively.

This is where polymers come into play. Flocculant polymers are added to the water after the coagulant to aid in the formation of stronger and larger flocs. The flocculant polymers have long-chain molecular structures that help bridge the flocs together, creating larger and more stable aggregates. The increased size and stability of the flocs improve their settling ability, making it easier to separate the suspended particles from the water.

Chemiphase offer different types of flocculant polymers used in water treatment, including:
  • Anionic Polymers: These polymers carry a negative charge and are often used in conjunction with positively charged coagulants like alum or ferric chloride.
  • Cationic Polymers: These polymers carry a positive charge and are sometimes used alone or in combination with negatively charged coagulants.
  • Nonionic Polymers: Nonionic polymers have no net charge and are used in situations where the water chemistry does not favor anionic or cationic flocculants.

The selection of the appropriate flocculant polymer depends on factors such as the water quality, the nature of the suspended particles, the coagulant used, and the desired treatment objectives.

Polymers in water treatment play a vital role in enhancing the efficiency of the flocculation process, leading to improved water clarity and quality. Additionally, the use of flocculant polymers can help reduce the amount of coagulants required, which can lead to cost savings and decreased chemical sludge production during the treatment process.
