A condition in which clays, polymers or other small charged particles become attached and form a fragile structure, a floc. In dispersed clay slurries, flocculation occurs after mechanical agitation ceases and the dispersed clay platelets spontaneously form flocs because of attractions between negative face charges and positive edge charges. Also used to increase the viscosity of water-base drilling fluids to enhance hole cleaning. Our flocculants are also used to increase bentonite yield and to clarify or dewater low-solids fluids.
Flocculants is a chemical that causes a dispersed colloidal system (such as clay) to coagulate and form flocs. Most flocculants are either multivalent cations such as calcium, magnesium and aluminum, or long-chain polymers. High pH, high salinity and high temperature can also cause clay flocculation. Flocculants are used to de-water or clarify low solid drilling fluids. They cause colloidal particles in suspension to group into clusters, whereby the solids separate out of the drilling fluid.
flocculent is used to flocculate clays, shales, and colloidal drilling solids encountered in drilling operations or can help reduce build-up of formation solids in a fluid system and reduce dilution rates for clear water drilling systems. flocculent is also suitable for use in freshwater and monovalent brines prior to filtration for fluid reclamation or for de-watering
