Answer:
Pre-Flush:
It is also known as In-line Equalization. In this stage of flow equalization, all the flow passes through the equalization basin. It helps in reduction of fluctuation in pollutants concentration and flow rate and helps to control short term surges with the use of basin.
Post-Flush:
Another name for this stage is Off-line Equalization. In this stage, only overflow above a predetermined standard is diverted into the basin. It helps in reducing the fluctuations in loading by a considerable amount and helps to reduce the pumping requirement. It is basically used to capture "first flush" from combined collection systems.

Explanation:
Strengthening is the method to improve the strength of material because different type of material property requires for different requirement .Some times requires more ductility,some time requires more strength.
When impurities are mixed with the pure metal then the strength of metal will increases and this is called the strengthening of metal.
The methods of strengthening are as follows
1.Solid solution strengthening and alloying
2.Work hardening
3.Transformation hardening
4.Grain boundary strengthening
5.Precipitation hardening
