why air blower is used in stp plant
STP blower is generally used for aeration in the ETP tank. The essential function of an aeration blower is to fulfill oxygen demands and maintain the treatment process at the lowest possible costs. A common measurement of proper airflow for the treatment process is to check the do (dissolved oxygen) concentration
What is the use of air compressor in sewage treatment plant?
There are three primary uses of compressed air in all wastewater treatment applications: Aeration to supply the processing bacteria with oxygen support. Agitation to keep the solids in suspension and, A continuous, driving pump to move the material.
why air diffuser is used in stp plant
An air diffuser or sparger diffuser is an aeration device typically is used to transfer air and with that oxygen into sewage or industrial wastewater or alternatively for mixing the large volumes. Oxygen is required by microorganisms/bacteria residents in the water to break down the pollutants.
What is BOD ?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water.
why acf is used in sewage treatment plant
