Wastewater can be reclaimed and reused for various environmental purposes, such as, creating artificial wetlands, sustaining streams and natural wetlands. It can also be used for irrigation of commercial nurseries and crops, and landscape irrigation, which includes irrigating school yards, parks, cemeteries, residential and golf courses. Wastewater further finds ample uses in industrial reuse and recycling, such as in water for cooling towers, makeup water, boiler feed, and in heavy construction etc. Nonetheless, when treated properly, wastewater becomes perfect for potable and non-potable urban use, for groundwater recharging and for numerous other uses.
Advantages of wastewater treatment
Wastewater should be treated in order to reduce the demand for freshwater, which is depleting day by day. There are many different processes of wastewater treatment, some of which may reduce the requirement for huge wastewater treatment facilities. This technology may decrease the volume of wastewater that is discharged, which benefits the aquatic environment. Capital cost of wastewater treatment systems is between medium to low, it is usually recovered within a short duration. Treated wastewater quality is sometimes even better than that of well water. Wastewater Clarification and Separation reduce the risk of diseases like shigella, giardia and E. Coli.
Processes of wastewater treatment
Membrane filtration systems
High pressure membranes are used for reverse osmosis or nanofiltration for treatment of water. The water thus produced is suitable for indirect potable use and for industrial processes requiring high-purity water. Low pressure UF or MF membranes effectively remove viruses. These…
