These polymeric compounds (possibly, polyacrylamide) of high molecular weight contain cationic, anionic and non-ionic functional groups. I especially like the deflocculant action which causes suspended particles to fall out of solution, reducing or eliminating the amount of pre-filtering needed. This can take place spontaneously or may be brought about by adding clarifying agents. Provided as a public service by the U.S. Environmental Protection Agency.

The term “deflocculant” denotes a substance which, when added to scattered particles in suspension, causes a reduction in apparent viscosity. Alum also been used to reduce algae growth by taking phosphorus, a nutrient for algae, out of the water. Environment Dictionaries. In the flocculation process, flocculants, or flocculating agents are generally added to the liquid so that flocculation is promoted and smaller particles (inorganic and organic), water-stable soil aggregates, or flocs/flakes agglomerate to form larger particles or lumps in the flowing medium. In such cases, the mathematical approach of Kynch [6] as applied by Talmage and Fitch [7] is more suitable. Deflocculating wetting and dispersing additives. Deflocculants. YEAST FLOCCULATING AGENTS [J. Inst. A reagent added to a dispersion of solids in a liquid to bring together the fine particles to form flocs.

Pigments for coatings are typically supplied as powdered materials wherein primary particles form larger agglomerates. Slip casting rate and viscosity are functions of temperature. seems therefore to be the outcome of the opposing effects of the deflocculating agent, the sugar, and the flocculating agent, ethyl alcohol. flocculating agent examples.

Aluminum sulfate (alum) has been used in man-made static water bodies as deflocculating agents. Three commercial water soluble flocculating agents supplied by Allied Colloids, UK, were used in the present work. Slips and casting are considered in terms of physical and colloidal chemistry. The main focus of this work was to develop a zero-VOC and APEO-free highly effective deflocculating wetting and dispersing agent with low foam and water sensitivity profile. An improved method for purifying kaolin clay containing colored impurities by forming a deflocculated aqueous slip of the impure clay and selectively flocculating the clay phase with an anionic polymeric flocculant, such as partially hydrolyzed polyacrylamide. Flocculating agents or flocculants are the chemicals or substances that facilitate flocculation or floccing up of suspended solids in liquid, typically associated with wastewater. Wetting and dispersing additives have been available for a long time now, frequently fatty acid-based with an adhesive group per molecule (anionic, cationic, non-ionogenic) and which can … Ref: BS, 5. Superior flocculation is achieved through the use of polyaluminum silicate sulfate which results in cleaner and more aesthetically pleasing water at a lower cost and with less waste material. Pluracoat® CF 20 is a nonionic deflocculation dispersing and wetting additive for water-based coating systems. deflocculating synonyms, deflocculating pronunciation, deflocculating translation, English dictionary definition of deflocculating.
