Sanprit’s Ferric Chloride is hydrolised in dilute solution forming a precipitate of Ferric Oxide. This precipitate absorbs suspended particles (clay, organic matter, etc.), flocculates and carries the absorbed particles to the bottom. lt also removes sulphides and silica. Sanprit’s Ferric Chloride is used to increase the rate of setting of sludge in town sewage by the process of hydrolysis forming Ferric Hydroxide which acts as a coagulant. Generally industrial effluents are alkaline and the treatment of such effluents is usually a costly and cumbersome multistage operation, requiring a number of chemicals. Sanprit’s Ferric Chloride, because of its flocculating and deodorizing properties, can be used directly in a single stage operation replacing the traditional cumbersome process.
