How does temperature affect flocculation
WebFlocculation is the process of bringing together the destabilized, or "coagulated," particles to form a larger agglomeration, or "floc." ... Variation in pH affects particle surface charge and floc precipitation during coagulation. Iron and aluminum hydroxide flocs are best precipitated at pH levels that minimize the coagulant solubility ... WebFlocculation has been chosen as an optimized method for harvesting microalgae at a low cost, and different flocculation technologies are also developed. Flocculation is a process in which agglomeration of suspended solids/cells occurs. Flocculation is either induced (with the addition of flocculating agents) or naturally happens (due to the production of the …
