What is water treatment process?

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.

1. Microfiltration

In this process, treated wastewater is pumped through filtration vessels that contain thousands of hollow fibers, similar to straws. The walls of these fibers have very fine pores, only 0.1 micron in diameter or about 300 times smaller than the width of a human hair.

2. Reverse Osmosis

Reverse Osmosis forces water under high pressure through membrane sheets with pores so small that chemicals the size of water molecules are generally the only substances that can pass through. The process removes viruses, bacteria, pharmaceuticals, large chemicals, and pesticides as well as organic matter.

3. Ultraviolet Light

After microfiltration and reverse osmosis, the water is exceptionally clean but as an additional safety measure, the water is sent through chambers that emit ultraviolet light to inactivate any remaining viruses and break down some of the remaining trace contaminants.

4. Advanced Oxidation

Valley Water is in the process of adding advanced oxidation to our pilot system for research and demonstration purposes. Advanced Oxidation is a process in which trace amounts of hydrogen peroxide is added to the water to reinforce disinfection. Future purification facilities will include this process at full-scale.

How to remove contaminants from water?

Regular household methods such as boilingwater or using an activated-carbon filtercan remove some water contaminants. Although those methods are popular because they can be used widely and inexpensively, they often do not remove more dangerous contaminants. For example, natural spring water from artesian wellswas historically considered clean for all practical purposes, but it came under scrutiny during the first decade of the 21st century because of worries over pesticides, fertilizers, and other chemicals from the surface entering wells. As a result, artesian wells were subjected to treatment and batteries of tests, including tests for the parasite Cryptosporidium.
