Question

Name the two different categories of microbes naturally occurring in sewage water. Explain their role in cleaning sewage water into usable water.

Answer 1

In the removal of pollutants and the processing of treated wastewater the physical, chemical and biological procedures are sufficiently safe for the environmental release. A biological method for waste water management consists mostly of special microbes for clean water.

Complete Answer:
- The method of extracting pollutants from urban wastewater, which includes primarily domestic wastewater plus some commercial wastewater, is sewage treatment. In the removal of pollutants and the processing of treated wastewater the chemical, physical, and biological procedures are sufficiently safe for the environmental release.
- A slurry or semi-solid waste is a byproduct of the disposal of waste, known as sewage waste. Before being suitable for dumping or application on ground, the sludge must undergo further treatment.
- A biological method for waste water management consists mostly of bacteria, some protozoa, and perhaps other special microbes for clean water. When organic pollutants are broken down into the food, the microorganisms stick together to create a flocculation effect that allows organic matter to settle from the solution. This leads to a sludge that is easier to handle, which is then dewatered and disposed of as solid waste.
- Bacteria and fungi are two types of microbes that exist naturally in wastewater. In the secondary treatment of sewages the bacterial and fungal mycelia form flocks. The primary effluent is put for secondary treatment following isolation of the grit and debris.
- The effluent is delivered to an aeration tank in which the air is injected into a continuously disturbed. The bacteria in these flocks absorb organic matter, thereby lowering the BOD in the wastewater. This is the outcome of a heavy increase in bacteria and the creation of flocks.

Note: The natural processes of microbial decomposition are optimized by biological industrial wastewater treatment systems to break down industrial wastewater pollutants, in order to extract them together with other undesirable products. They also substitute physical and chemical therapies (sometimes used together) that could be one of the better options.
