Zero discharge of water

Zero discharge of water


In the end of the 1980’s, together with increased environmental awareness within society and industry, “Zero discharge” changed from a technical description of 100% wastewater recycling to a “goal”. The principle of “zero discharge” is recycling of all industrial wastewater. This means that wastewater will be treated and used again in the process. Because of the water reuse wastewater will not be released on the sewer system or surface water.
The U.S. Clean Water Act Amendments even stipulated zero discharge promotion. The goal of the Clean Water Act was to make U.S. waterways fishable and swimmable by 1983 and to achieve zero discharge of pollutants to waterways by 1985. Zero discharge has become effective in specific sectors; agriculture (water reuse for irrigation), semi-conductor and in specific geographical areas; Middle East & Asia, where water shortages have made zero disposal a necessity.
