WebFlocculation as seen by engineers. Flocculation is a process where a solute comes out of solution in the form of floc or "flakes." The floc may then float to the top of the liquid, settle to the bottom of the liquid, or can be readily filtered from the liquid. The floc operation may be expedited by adding some chemicals. WebFeatures and benefits include: High molecular weight, high charge water soluble chemistry effectively function as coagulants when charge neutralization is required. Functionality over a wide pH range, pH 5 – 10, eliminates the need for pH adjustment. Core Shell Flocculants. Our Core Shell™ polymers are proprietary, high molecular weight ...
WebMar 5, 2024 · Dry vs. Liquid Polymer. Wastewater treatment polymers usually come in either a dry granular form or a liquid form. The liquified polymers are known as emulsions and contain surfactants and emulsifying agents. They are roughly 1/3 equal parts, and the agents are required to keep the flocculant portion in a readily available condition. Surface chemistry In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid.
