IntroductionWastewater management encompasses a broad

range of efforts that promote

Effective and responsible water use

Proper Water treatment

Proper Water disposal

Encourage the protection and restoration of our nation's watersheds.

What is waste water

“It is the water which is discharged from buildings, houses etc which is unfit for consumption.”

Composition of waste water Most wastewater from a

building is sanitary wastewater which includes human waste, cleaning solutions, oil and grease from

cooking, food particles, and soil from cleaning clothes

and floors

Commercial establishments may also discharge metals, acids and bases, and small particles of plastic, glass, stone, etc

Problems with waste water

If not treated properly causes water pollution

Can lead to various health hazards

Can cause soil pollution

How to detect

Any oxidizable material present in a natural waterway or in an industrial wastewater will be oxidized both by biochemical (bacterial) or chemical processes.

Since all natural waterways contain bacteria and nutrients, almost any waste compounds introduced into such waterways will initiate biochemical reactions

How to detect

Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD) and Chemical oxygen demand (COD)

Both have been widely adopted as a measure of pollution.

Solutions

REUSE

RECYCLE

WATER TREATMENT

Reuse Some relatively

clean wastewater can be reused without treatment

Graywater is wastewater generated by washing, laundry, and bathing (not from toilets) 50-80% of domestic

wastewater Reused for irrigation

or flushing toilets

Recycle Closed-loop

treatment systems Used to capture, treat,

and reuse waste water on-site

E.g Car wash System

Wastewater reclamation

Treats waste water and use it for a different purpose

E.g MC waste water treatment and use for irrigating parks

Discharge and treatment Wastewater is

transported to an (on-site or off-site) treatment facility, treated, and discharged into a water body

Used for drinking purposes

Save water : Save life
