Waste water:
Waste water is a type of water that is due to the environmental pollution or pollutants influence and it has an unfavorable affects in quality.There are so many techniques used for the management of wastewater.
Techniques for management of waste water:-
1-Operative miscellaneous chemical system:
This system is used for excrement that is conveyed in sewers and the waste water industries that use the airand a biologically clumped mass of fine particles composed of bacteria and protozoa.
Firstly the air and oxygen is provided to the excrement of the sewage or the industrial waste water that reduce the organic content quantity in the sewage and produce the biological mass. This waste water and biological mass both are mixed with each other and called" mixed liquor ".this is also called the primary treatment. The sufficient primary treatment is done with the waste water. After this excess mixed liquor is poured in the setting chamber and treats it with the supernatant results liquid lying above a solid residue. Solid residue is called sludge and it discharge in the aeration system and the new waste water enters the tank. This process is called fractional process and the sludge is called "return operative sludge"and the sludge present in huge amount is called "excess operative sludge" or "useless operative sludge" removed by the treatment of decomposition. This decomposition process may be occurs in the presence or absence of oxygen.
2-Carbon filtering treatment:
It is the process through ...

...n which a somatic separation process occours.in this system no chemical reaction happens.Water is distilled by the distillation system to remove scums; we can say that this method is used to purify the seawater.
In this purification system, the vapor directlyfeds into a chamber. Subsequently, the concentrate is not pure butsomewhat,at the given temperature and pressure, its configurationmatches to the configuration of the fumes. At the end, simple purification is operative only when the fluid boiling points changes significantly (25 °C). For these circumstances, the vapor pressures of the constituents arenecessarily different that the concentrate may be adequatelyclean for its future.
There are many types of distillation process.
Some of them are given below and which are commonly used now a days:
1-Fractional distillation
2-Vaccume distillation
