Question

Race way have a capacity of self purification (Earthfill/Concrete/Stone pitched)​

Answer 1

Answer:

raceway, also known as a flow-through system, is an artificial channel used in aquaculture to culture aquatic organisms. Raceway systems are among the earliest methods used for inland aquaculture. A raceway usually consists of rectangular basins or canals constructed of concrete and equipped with an inlet and outlet. A continuous water flow-through is maintained to provide the required level of water quality, which allows animals to be cultured at higher densities within the raceway

Answer 2

A raceway typically consists of concrete rectangular canals or basins with an inlet and an exit. A river has the ability to purify itself.

• The effluent is stabilized through self-purification, but the biodegradation process is slowed down by a lack of oxygen.
• In a natural setting, if the water is completely depleted of dissolved oxygen, roughly 3 g of oxygen can be dissolved per m2 per day; this is the extent of the capacity for self-purification.
• If allowed enough time and space, a stream or river can naturally purify itself.
• This is known as self-purification.
• For instance, when sewage water is dumped into a body of moving water, natural processes take place and some types of pollution are removed from the water.
• Many factors, such as volume, flow rate, flow turbulence, change in sunlight, etc., affect how quickly and completely the self-purification process occurs.

Race way that has a capacity of self purification is a river.
