Answer 1

Answer:

every year sewage is cleaned by water treatment plant

Answer 2

Explanation:

•The demand for clean water and to this water treatment will continue to gain importance. Apart from the worldwide increasing drinking water needs, further municipal and industrial processes are also reliant on efficient solutions for water supply.

•Apart from water treatment processes, dissolved air flotation is most widespread in sewage technology, because it has proven as an economic and efficient process both with municipal and industrial sewage treatment.

Water treatment plants are used to clean sewages and pipes.

•The dissolved air flotation (DAF) is a chemical/physical waste water treatment process where water is first pressurised and saturated with gas or air. Subsequently, the water is reduced to atmospheric pressure, whereby a corresponding gas air proportion is released in the form of finest bubbles. In the solid substances, these micro bubbles form an agglomerate which due its low density rises to the surface of the flotation tank and can be mechanically cleared up here.
