Kemira is a global supplier of water-soluble polymer technologies used in a wide range of applications, including industrial and municipal water and wastewater treatment processes. We deliver patented polymer and applications technologies, which in combination provide significant performance advantages. Through our extensive polymer research, we are experts at solving wastewater treatment problems. This capability derived from Kemira’s expertise in polymer architecture and application know-how, provides customers with a valuable resource for improvement in their daily operations. Our technical service, customer service and sales staff complement the manufacture of high quality polymers to support the market needs. Kemira’s water-soluble polymers include both organic coagulants and flocculants for various end-use customer applications.
The most commonly used organic coagulants consist of two primary families of products both referred to as polyamines. These are POLYDADMAC (or POLYDMDAAC) polymers and EPI-POLYAMINES (or DMA-EPI POLYMERS). They are offered in several different molecular weights and solution concentrations. We also offer both of these chemistries in NSF certified products for drinking water (potable) applications. A third category of cationic coagulant, dicyandiamide (DICY POLYMER) is offered for specific industrial applications. All organic coagulants are 100-per-cent cationic charge materials.
Kemira’s flocculants are high molecular weight water-soluble polymers used in numerous industrial applications. They are available in a wide range of charge type, chemistry (monomers used), charge density, molecular weight and architecture (linear, branched, structured). We produce charge ranges that cover the gamut from one-hundred-percent anionic to non-ionic and to highly cationic. Molecular weights are available up to approximately 10–15 million Daltons. We produce flocculants in emulsion and dry powder forms and offer linear polyacrylamides, copolymers and terpolymers of various cationic and anionic monomer types. Our manufacturing facilities can produce products covering the broadest range of physical and chemical specifications to satisfy the demands of even the most challenging applications.
Flocculants are used in almost every industry and in innumerable applications worldwide. Our products and expertise are “world class” and we develop treatment programs that provide environmentally friendly, cost-effective results.
