In addition there are minor ailments, such as ear and eye infection and skin lesions, which are contracted merely by contact with the water. Respiratory disease may...

Disinfection Of Waste Water In this era of pollution awareness, a great deal of interest is centered upon the improvement of these effluents for industrial and agricultural reuse. The ultimate goal is of course reclamation of these effluents for industrial and agricultural reuse. the properties of...

The chemistry of the chlorination of potable water, waste water and industrial waste is fundamentally the same. The reaction differ only because of the difference in species and amounts of interfering substances, both organic and inorganic. The interfering substances are those that either...

Water Analysis for Chlorine The amount of residual chlorine left in the chlorinated water after the required contact period, can be experimentally determined by using any of the following tests: Orthotolidine test DiethIy-p-Phenylene-Diamine (DPD) test Chloroscope Orthotolidine Test In this test,...

Water Disinfection Method Disinfection Water treatment process can be control microorganism. This Disinfection designed by  water treatment plant product water storage tank or online pipe line in water treatment plant. Ozone Water Treatment: Ozone gas, O3, is a powerful disinfecting agent that can...

Safety Require for Water Treatment Plant Chlorine Cylinder  Room. Chlorine house should have to following features: The chlorine cylinders and feeders should be housed in an isolated room from the Water treatment plant, easily accessible, close to point of application and convenient for truck...

Hypochlorinators The simplest method of continuous chlorination of water supply systems for a water flow of less than 200 Lpm is by the use of a hypochlorinator. Hypochlorinators are motor driven pumps which are used to add hypochlorite solutions to water. The pump pulls the hypochlorite solution...

The efficiency of the disinfection depends upon the following factors: Nature of the disinfectant, Dose of the disinfectant, Length of contact time with the disinfectant, Temperature, Type and concentration of organisms in water to be disinfected, and pH of water Dose of Disinfectant A variety of...

Types of chemical disinfectants containing chlorine are hypochlorite, chloramines, and chlorine-dioxide. Hypochlorites Instead of using chlorine gas, some plants apply chlorine to water as a hypochlorite, also known as bleaching powder. Hypochlorites are less pure than chlorine gas and are less...

Disinfectant Chlorine (CL) gas is a greenish yellow in colour and about 2.5 times heavier than air. Liquid chlorine is amber coloured and about 1.44 times heavier than water. CL gas is moderately soluble in water with a maximum solubility of about 1 % at 10°c. When chlorine is added to water, it...

Disinfection is the process of selectively destroying or inactivating pathogenic organisms present in water, usually by chemical means. Disinfection aims in reducing the organisms in water to such low levels that no infection of disease results when the water is used for domestic consumption...
