AERATION FOR WASTE WATER MANAGEMENT
As per the UN report nearly 80% of world’s waste water is discharged into environment without treatment which further pollutes the environment and disturbs ecosystem. Waste Water Management is need of the hour. Waste water treatment is referred to a waste water treatment. It is a process of converting wastewater into effluent water which is suitable for use and can be discharged back to water cycle. The waste water collected in treatment plants is mainly the industrial and municipal waste which needs to be treated and made healthy for use. Aeration is one of the most important processes used for treatment. It is the most biological treatment used for waste water management. It is also known as Supplemental Aeration which means adding up or injecting the oxygen into water resource in order to raise concentration of oxygen in water which
Supplemental Aeration is one of the vital steps in process of waste water management. The process of Aeration includes pumping the air into the waste water tank which boasts the micro organism growth in water. These micro organisms break down the organic compounds and nutrients present in water. Breaking down of nutrients is necessary for controlling the amount of nutrients in water. Nutrients are useful only if present in a adequate amount, both less and more are unhelpful for the waste water treatment. Maintaining the ideal level of nutrients is necessary in waste water management as if nutrients amount is more than ideal level in water. Abundance of nutrients leads to over growth of algae and weed in water which can cause dead zones or can also slowly kill the water body.
The Supplemental Aeration is process under which adequate level of dissolved oxygen is maintained in water which helps in various ways. Oxygen concentration in water tank is basic for microbial to survive and carry out waste water treatment. Level of dissolved oxygen is tank impact the health of micro organisms which break down the extra nutrients, maintaining pH levels and stabilise waste water.
