Lamella Clarifier Settling Tank for Waste Water Treatment

Description:

Bleach is made by reacting chlorine gas with calcium hydroxide (hydrated lime).Because absolutely dry calcium hydroxide does not react with chlorine gas, chlorine can only be adsorbed by calcium hydroxide.Therefore, in industry, hydrated lime containing less than 1% free water is used for chlorination, and the chlorine gas used also contains less than 0.06% water.The free water in these raw materials is used to hydrolyze chlorine gas to produce acid (HClO, HCl), and the resulting acid is neutralized by hydrated lime.Then, depending on the water precipitated from calcium hydroxide during the chlorination reaction, the chlorine will continue to be hydrolyzed, and more calcium hydroxide will be involved in the reaction process to generate a series of compounds.Bleach is a complex of these compounds.

Application & Use Ratio:

1. Bleaching liquid: 6.5%, by dissolving 100g of 65% calcium hypochlorite in 1000L of water.

2. Disinfectant fluid: 1ppm, by dissolving 1.7g of calcium hypochlorite in 1000L of water.
3. Calcium hypochlorite can be widely used as algicide, bactericide disinfectant, bleaching agent or oxidant because of the available chlorine in the product. For example, it has a wonderful disinfections for swimming pool, drinking water, cooling tower& ore dressing and waste water, food, farming, fishery, hospital, school, station and household etc., good bleaching and oxidation are also found in paper and dye industrial.
