Question : What is water recycling? Explain the conventional wastewater recycling treatment?

Answer»

Solution :Water recycling is reusing treated wastewater for beneficial purposes such as AGRICULTURAL and landscape irrigation, industrial processes, flushing in toilets and ground water recharge. Conventional waste water treatment consists of a combination of physical, chemical and biological processes which remove solids, organic matter and nutrients from waste water.
The waste water treatment involves the following stages:
Primary treatment
Primary treatment involves temporary holding of the waste water in a tank. The heavy solids get settled at the bottom while oil, grease and lighter solids float over the surface. The settled and floating MATERIALS are removed. The remaining liquid may be sent for secondary treatment.
Secondary treatment
Secondary treatment is used to remove the BIODEGRADABLE dissolved organic matter. This is performed in the presence of oxygen by acrobic microorganisms (Biological oxidation). The microorganisms must be separated from treated waste water by sedimentation. After separating the sediments of biological solids, the remaining liquid is discharged for tertiary treatment
Tertiary treatment
Tertiary or advanced treatment is the final step of sewage treatment. It involves removal of inorganic constituents such as nitrogen, phosphorus and microorganisms. The fine colloidal particles in the sewage water are PRECIPITATED by adding chemical COAGULANTS like alum or ferric sulphate.

Answer»

Solution :1. Fish are obtained by capture FISHERY and culture fishery.
2. Composite culture is the method by which different species of fish are reared in the same pond. The fish selected for such FARMING have different food preferences and thus they do not compete for the food with each other.
3. Advantage / Merit of the composite culture: The advantage is that the food is notwasted. The same ond is optimally utilized for the REARING to five to six different varieties of fish. This becomes economically beneficial and also save on time.
4. Disadvantage /DEMERIT of the composite culture: The disadvantage is that though the different fish grow in same pond, their breeding is affected.
5. They must be bred by induced breeding PRACTICES or their naturally occurring seeds should be collected at the time of their natural breeding. Since many fish breed during monsoon, collection of fish seeds also become problem.
