Equipment for Biological Treatment of Water

Water used for drinking and household use, even water from a ground water supply, should be treated before it is used to ensure it is safe and aesthetically pleasing. Biological water treatment is one of the innovative methods of water treatment. This process involves the use of naturally occurring micro-organisms in ground water to improve water quality. In optimal conditions, the micro organisms break down material in the water such as dissolved organic carbon and iron. In this way it improves water quality.

Why use biological treatment of water?
The biological treatment of water is well suited to treat some common problems to ground water supplies, such as iron, arsenic, and dissolved organic carbon (DOC). It also treats colour and turbidity. It has been proved that the biological treatment system, including a slow sand filter and biological activated carbon filter, effectively reduces colour, turbidity, DOC, as well as iron and arsenic.

How will biological treatment improve water quality?
Biological treatment of ground water enhances the water quality by decreasing the amount of arsenic and iron, which are health and aesthetic problems, respectively. This process also reduces the turbidity and color and also the concentrations of DOC. All these factors can cause helath problems in chlorinated water. The decreased level of DOC enhances the taste and odour of the water, and it can also reduce the amount of chlorine needed for disinfection.
