Water is the common name applied to the liquid form (state) of the hydrogen and oxygen compound H2O. Pure water is an odorless, tasteless, clear liquid. Water is one of nature's most important gifts to mankind. Essential to life, a person's survival depends on drinking WATER>>

The World Health Organization estimates that

Approximately one billion people do not have access to a reliable water supply.

Approximately 2.6 billion people lack basic sanitation. As a result, approximately 3.4 million people die annually from water related diseases

Even in the developed world, water shortages can have a tremendous impact, not only on health, but on industries such as agriculture, manufacturing, and power production.

Protect your Water as your

Child……………..

Actually, only 1% of the world's water is usable to us. About 97% is salty sea water, and 2% is frozen in glaciers and polar ice caps. Thus that 1% of the world's water supply is a precious commodity necessary for our survival..

"If water is life...water conservation and reuse

must be our way of life."

Dinosaurs have vanished, but many organisms

continue to live without much change in their

form for millions of years.

Water Reuse• In the paper industry

In the paper industry water can be recycled by means of membrane filtration and membrane bio reactors. (MBR)

• In the textile industry For water recycling in the textile industry membrane filtration is a preferable option compared to other wastewater treatment techniques.

• In the poultry industry By means of filtration and ozone disinfection, cooling water can be recycled.

• In the food and beverage industry Water recycling using UV-disinfection and membrane filtration in the food and beverage industry.

Water Reduce/Recycle• Water disinfection and recycle in greenhouse horticulture

Water recycling and disinfection by means of heat treatment, sand filtration and ozone- and UV treatment.

• Water treatment and reuse/recycle of oily wastewater

By means of membrane filtration and ozone/UV treatment, oil can be removed from wastewater.

• Water savings and recycle for cooling processes in which surface and ground water is used

Cooling water savings by means of open recirculating cooling towers.

• Water reuse/recycle for agricultural irrigation

The use of municipal wastewater effluent for agricultural applications
