Particles finer than 0.1 µm (10 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces. These larger and heavier particles are called flocs. WebClarifiers and flocculants work in the same way to achieve the same result. Each of them aggregates the tiny-sized bits of suspended material in pool water so that these bits can be more quickly separated and removed. …

Web1. A clarifier has an inlet for raw water with particulate contaminants, a flotation tank where the contaminants are flocculated by a chemical agent added to the inlet water and floated to the surface of the water in the flotation tank by microscopic air bubbles where they form a floating layer of sludge, a layer of a filtration medium disposed at the bottom of the … WebThis paper presents the results of investigation on uptake of radioactive species ~(90)Sr and ~(l37)Cs present in the liquid effluents from nuclear processing plants.
