New Technologies for Water and Wastewater Treatment

Wastewater Treatment
Wastewater treatment is needed so that we can use our rivers and streams for fishing, swimming and drinking water. For the first half of the 20th century, pollution in the Nation’s urban waterways resulted in frequent occurrences of low dissolved oxygen, fish kills, algal blooms and bacterial contamination. Early efforts in water pollution control prevented human waste from reaching water
supplies or reduced floating debris that  obstructed shipping
New Technologies for Water and Wastewater Treatment
Water is an essential substance for living systems as it allows the transport of nutrients and waste products in living systems. Research shows a clear correlation between diseases and the amount and types of fluids consumed, health-promoting properties of nutrients which can be added to water, optimal intake levels, and consumption patterns. Although three quarters of the Earth’s surface is covered with water, most of that water is not suitable
.for human consumption. Today, hundreds of millions of people in vast regions of the world do not have access to water to meet their basic need
