Webaddition of coagulating or flocculating materials ; [2] their dispersion through-out the fluid; [3] agitation to bring the particles in contact with the coagu-lating agents and with each other ; and [4] agitation to consolidate the grow-ing particles into agglomerates of suit-able size and density. The last two agitation phases may be termed WebParticle aggregation. Particle agglomeration refers to formation of assemblages in a suspension and represents a mechanism leading to the functional destabilization of colloidal systems. During this process, particles dispersed in the liquid phase stick to each other, and spontaneously form irregular particle assemblages, flocs, or agglomerates ...
WebFlocculating particles are produced by coagulation, and a column analysis indicates that an overflow rate of 20 m / d will produce satisfactory removal at a depth of 3.5 m. Determine the size of the required tank (and dimensions from … WebSep 22, 2024 · Controlled flocculation can be achieved by a combination of control of particle size and the use of flocculating agents. The most common categories of flocculating agents are electrolytes, surfactants, and polymers. i. Electrolytes. Electrolytes act by reducing the zeta potential, which brings the particles together to form loosely …
WebFlocculation is a process whereby small particles in suspension are caused to aggregate, giving large clusters (flocs) that are much more easily separated than the original particles. ... Thus, if it is assumed that most collisions in a flocculating suspension are between flocs of roughly equal size, it may be reasonable to treat all of the ... WebFlocculation is a process that is widely used in industrial applications, such as biotechnology, mineral processing, papermaking, water and wastewater treatment, and …
WebThis is primarily due to the individual particles flocculating into larger aggregates which are significantly less dense than their component primary particles. An individual floc may constitute up to 10 6 individual particles, and flocculation is a dynamically active process which is directly affected by its environmental conditions; this ...
