The main benefits of flocculants in wastewater treatment

FLOCCULANTS are designed to separate suspended solids and liquids in a wide variety of industries and applications, also to improve the efficiency of your process water, raw water, wastewater, and potable water treatment systems.

Gpc Clear Solutions objective is to design a program which will meet your company’s water quality performance goals, regulatory requirements while improving cost performance.

Chemical coagulation and flocculation are effective in the removal of suspended solids in wastewater. During the solid-liquid separation process, coagulants are added which destabilises the colloidal suspension. Flocculants are then introduced to collect the coagulated solids resulting in larger flocs of suspended solids content in the wastewater.

The larger flocs separate resulting in clear water. The majority of these chemicals added to the process do not stay in the aqueous phase. They are attached to the solids that are further processed and removed from the treatment area.

FLOCCULANTS by definition means a process in which individual particles of a suspension form aggregates. In the water treatment industry, the terms coagulation and flocculation imply different mechanisms. Flocculants consist of various molecular weight anionic, nonionic and cationic polymers. They are used to increase the efficiency of settling, clarification, filtration and centrifugation operations.

FLOCCULATION is used to describe the action of polymeric materials which form bridges between individual particles. Bridging occurs when segments of a polymer chain adsorb on different particles and help particles aggregate. The benefit of a flocculant is that it can carry active groups with a charge which will counterbalance the charge of the particles, and adsorb on particles and cause destabilization either by bridging or charge neutralization.

An anionic flocculant will usually react against a positively charged suspension (positive zeta potential). That is the case of salts and metallic hydroxides.

A cationic flocculant will react against a negatively charged suspension (negative zeta potential) like silica or organic substances.

Our high standard chemicals come in various grades and forms which are available for use depending on the application.

  • Anionic emulsion grade polymers
    A range of high molecular weight anionic water in oil emulsions. These products are suitable for inline dilution before being added to an application. These are available in 25KG kegs or 1050KG IBC containers.
  • Cationic emulsion grade polymers
    A range of linear and structured cationic water in oil emulsions. These products are also suitable for inline dilution before being added to an application. These are available in 25KG kegs or 1050KG IBC containers.
  • Anionic powder grade polymers
    Anionic powder grade polymers are available in low, medium and high molecular weights. These are available in 25KG or 750KG bags.
  • Cationic powder grade polymers
    Cationic powder grade polymers are available in a range of molecular weights and structures. These are also available in 25KG or 750KG bags
