Water is the basic determinant for the existence of life on earth. Water is required in everyday life in the domestic, industrial, commercial and agriculture sectors abundantly. With the increase in population growth, environmental pollution and growth of technology, water gets polluted very easily through the waste materials from these sources and it becomes very imperative to treat water we use. It is equally important to treat the waste water too in order to check pollution of the water bodies and the ground water. The purpose of treating water is to rid of the water contaminants present in the water and make it fit for consumption. The treated waste water is let out in to the environment without causing any negative impact on ecology.

The water and waste water needs treatment for the following reasons:-

• Conservation of water sources.
• Protection of environment.
• Maintain a healthy life for human beings.

In the modern world, providing water treatment solutions has occupied a prime position and has developed as a major industry, extending services in the sectors of domestic, industry, agriculture etc.

The basic product which is used in treating water and waste water is carbon. The activated carbon is a processed carbon that has high level of micro porosity and makes possible the chemical absorption very quickly. The activated carbon finds its use in water purification and waste water treatment, apart from applications in other areas. It is a process by which the contaminants in both the water and waste water are removed.

Removal of nitrogen and phosphorus from waste water is another way of purification by which process the nitrogen gas is removed from the waste water and released to air. Disinfecting the contaminated drinking water is mainly done to minimize the level of microorganisms in the treated water. The commonly used methods used for disinfection of water are ozone, chlorine or ultraviolet light.

Chlorination

The most commonly adopted method of treating water and waste water through chlorination which is cost effective. Since the toxicity of residual chlorine will affect aquatic species, it is essential to dechlorinate the treated effluent.

Ultraviolet

In ultraviolet no chemicals are used and the treated water will not affect the consumers of treated water. The radiation of UV damages the bacteria’s genetic pattern and renders them unable to reproduce.

Ozone O3

In this process, the Ozone O3 is produced through combining O2 and a third oxygen atom and destroys many micro organisms. The disadvantage of this process is the high cost of the equipment for generating ozone.

Water treatment solutions depend on the nature of the water bodies and the intensity of contaminants present in water. In addition to the above mentioned general water treatment solutions, there are many companies who have designed their own water treatment solutions by obtaining patent for their technologies.
