PACKAGED EFFLUENT TREATMENT PLANT
Water is most important part in everyone’s life whether it belongs to personal life or industrial life. No one can live without water and even no production can occur without it. So it becomes necessary to utilize the available water to the maximum extent or not to destroy the same hazardously. However, the quantity used by different industries may be differ due to different usage but still much of the important task such as washing, drinking, dilution etc. are performed through water only. If the industry has a right to use the water then it becomes their duty to make it clean or re-usable. Industries consumed the clean water and generate the polluted water which includes harmful chemicals; oils, grease, solids etc. water produced through the industrial process is treated as called “waste water” or “Effluent”.
WHAT IS SEWAGE?
Here the main work starts to clean the pollutants through the effective water treatment. So plants are established for this process and these plants are called “Effluent Treatment plant”. As the name suggest, it involves removing the pollutants under the water to make it usable for another process and so to make the environment pollution free.
Sewage is of usually three types:-
1. Domestic Sewage: This is the result of household chaos. Daily routine work includes bathing, toilet, washing clothes or kitchen utensils, cleaning etc. This kind of disposal are of grey color which is later recycled for re-use purposes. This recycled water is used for further planting, harvesting or for other nature related work. This sewage is also called sanitary sewage. This sewage can be purified with an extent of 99.9% but yet it includes some harmful stuff which cannot be re-used for the same purposes.
2. Industrial Sewage: This is generated through the activities performed in industry or factory outlets. This contains the poisonous chemicals, solids, oils etc which cannot be dissolved in water and so they ruin the water completely. Their cleanliness percentage resembles only 0 .1% and that’s why it cannot be re-used for any purposes. This sewage is quite smelly and of black color which could results of harmful diseases for the surrounding peoples.
3. Storm Sewage: Rain water and other natural water contain the organic materials which are not at all harmful. Dissolved dust is purified to make it re-usable and supplied through pipelines.
The main goal of treatment is to make the waste water re-usable or smoothened the flow of water lying on roads or lands or coming from the different outlets. This treatment is performed as per the local, state and federal regulations or standards.
