Understanding Microbial Treatment Of Wastewater

There would be no kind of aquatic life supported if waste water was just released into dams, rivers, lakes and seas. The effluents contain organic matter that would bring about competition for oxygen. In order to avoid such a situation, microbial treatment of wastewater is done before being discharged to the environment.

The process involves aerobic bacteria which break down and degrade organic wastes into a more manageable form. The bacteria also act on solids in primary phase of the process to help minimize the production of sludge. This makes the next steps in a waste water treatment process much easier because they would otherwise be compromised by the sludge.

The bacteria are also usually introduced on sludge to completely decompose any organisms that might be remaining. This process also reduces the water content hence only a small volume of sludge remains. The sludge is also known to produce an odor which is reduced by the bacteria.

Aerobic bacteria survive only when enough oxygen is available. The treatment process is either carried out in an open lagoon or an enclosed tank that is aerated. In the open lagoon, the process might take up much time because oxygen supply is limited at only 21 percent of the air available. The enclosed tank procedure is usually oxygen being directly fed to the tank and fused directly with the waste water and hence bacteria action is much faster.

Microbes are also used to absorb nutrients like nitrogen and phosphorus in the waste before it is released. This is meant to avoid algal blooms in receiving waters. This is so especially for water that may be containing soaps and detergents.

It is both economical and efficient to carry out a microbial treatment of wastewater. The process is friendly to the environment. It also leaves the water safe for recycling.
