Characteristic Properties of Water
Pure water is virtually a non-conductor of electricity. On heating to a very high temperature water molecules are dissociated into the elements. The formation of water front...

What is Hardness?
Hardness is caused by hard water containing high concentration of calcium and magnesium ions. Water is considered to be hard if it has a hardness of 100 mg/L or more...
CHLORINATORS
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...
TYPES OF DISINFECTANT
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,...
Advantages and Disadvantages of Water Softening
Advantages of water Softening are:
Water Softening will deal with the problems caused by hard water such as excessive soap use and scaling.
Depending on the type of water softening process used, softening may...
Efficiency of Softening
In addition to raw water characteristics, the operation of the softener can influence efficiency of softening. The most important factors in softener are resin, flow, and cleaning.
Both the resin type and...
