How can we use purified waste water?

-IRRIGATION USE

-CIVIL USE

-INDUSTRIAL USE

We have developed the irrigation use.

We can reuse wastewater to irrigate crops intended for human or animal consuption, crops for the production of electricity or gardens, sports fields and green spaces irrigation.

composition of Wastewater

Though the actual composition of wastewater may differ from community to community, all municipal wastewater contains the following broad groupings of constituents:

-Organic contents – The organic content of wastewater can be size of classified as nitrogenous and non- nitrogenous.

Proteins, urea, amines, and amino acids are included in nitrogenous compounds where as soaps, fats, and carbohydrates are included in non-nitrogenous compounds Nutrients (Nitrogen, Phosphorus, Potassium)

-Inorganic matter (dissolved minerals)

-Toxic chemicals   

-Bacteria – There can be an aerobic bacteria which requiring air for survival and an anaerobic bacteria which flourishing without air or facultative which carrying on with or without air. Some of the bacteria can be pathogenic which causes intestinal diseases. If these pathogenic bacteria are present in the effluent, chlorination and other methods of treatment should be necessary to apply to eliminate the bacteria before disposing. However, bacteria is also important in wastewater stabilization, i.e., it breaks it down into substances that do not decompose further

-Pathogens

This is the wastewater reuse in the world

The irrigation water cames from:

-industrial dangerous and not dangerous, or domestic gray and black wastewater that must be purified by wastewater treatment plants.

-rainwater without needing to be purifiel.
