Coagulants: Polymers used to bring together suspended solids less than 0.1 milli-microns in size. These products can be positively charged (cationic), and carry varying molecular weights. Some examples of coagulants are inorganic salts or polymeric polymers such as polyamines, DADMAC, ACH or PAC.

Flocculants: Polymers used to bring together suspended solids greater than 0.1 milli-microns that are comprised of repeating molecular units. These products can be manipulated by varying the molecular weight chains or by changing the charge density on the molecular units.

Why Use Coagulants and Flocculants?

Suspended solids in aqueous solution exhibit Brownian movement, which keeps them in constant motion, inhibiting settling. The purpose of HYDROFLOC™ polymers is to neutralize the like charges in suspension by coagulating and/or flocculating them into a larger particle size. The larger the particle size, the faster the settling. Hence, improved settling and cleaner supernatant are achieved rapidly.

There are three types of HYDROFLOC™ flocculants available: cationic – positive charge, anionic – negative charge, and non-ionic – no charge. Each type of polymer is available in three different forms: liquid, emulsion and dry powder. Our polymers are available in multiple molecular weights from very low to very high.

Due to the variety of different waste streams, HYDROFLOC™ polymers are applied based on the chemical footprint of the specific waste stream. We recommend jar testing in order to ensure that the optimum and most economically advantaged product are applied.
