Iron and Steel industries in India are one of the best in recycling of raw water.
Once the source of water is identified, raw water is pumped into an Intake well.
The dimension of the Intake well is designed as per the water requirement of the
plant. From the Intake well water is pumped to Central Influent Water Treatment
Plant (IWTP), which is designed to supply the following four qualities of water
required for operation :
a)
Filtered water
b)
Demineralised water
c)
Soft water
d)
Drinking water
Different quantities of water is pumped into different plants for operation.
Effluents from different plants are collected in the Central Effluent Water
Treatment Plant (EWTP). The EWTP is designed to treat the following types of
waste water generated within the Steel Plant.
1.
Inorganic effluents including cooling tower blow down effluents from
various unit operations.
2.
Waste water collected from steel melting shop, Hot strip mill section.
3.
Oily waster water.
4.
Organic waste water from Coke oven plant.
5.
Waste Water from influent water treatment plant.
6.
Sanitary waste from Canteen and Toilets of office complexes.
7.
Waste water collected from different sections like, machine shops,
laboratories, medical facilities.
