What’s Happening !

Source : ET 6th March 2016

Need of the Hour: Use & Manage Water Better

Water Vital Resource

•Major component for most industrial processes

•Critical for sustaining life – Human consumption,

food security

•Increasingly scarce and polluted

• Conventional Sources :

• Surface Water

• Ground Water

• Non Conventional / Alternate Sources

• Recycled Waste Water

- Industrial Waste

- Domestic Sewage/Sullage

• Sea Water

Water Crisis – In India

India expected to be severely water stressed by 2025.

This also relates to food.

ZERO LIQUID DISCHARGE SYSTEMS

(ZLD)

SESSION OBJECTIVE

To share our experience & capabilities in creating new sustainable sources

of water through Zero Liquid Discharge (ZLD) systems

Recycling Sewage

How much water is needed/person ?

• Bathing – 55 ltrs

• Toilet flushing – 30 ltrs

• Washing of cloths – 20 ltrs

• Cooking/Drinking/washing utensiles -30 ltrs

• Total 120-150 Ltrs/Person/Day

Alternate Sources

• Waste Water can be an sustainable source of Water

• Community Sewage can be effectively recycled for Industrial as well as secondary uses in Communities

• Industrial waste water is an excellent resource for Industrial uses

Technology Options

• Sewage : NGPSTP, FMR, MBR, SBR, ASP..

• Industrial Water : SBR, Disinfection & Filtration options, MBR, UF, RO, NF, Ion Exchange

• Sea Water : RO, Thermal Technologies

Options for Reuse

A) Urban Reuse

• Landscaping

• Fire Protection

• Dust Control

• Concrete Mix at Construction sites

• Vehicle & Window Washing

• Toilet Flushing

• Cooling Water

• Boiler Make Up

• Process Water (for SEZ and industry clusters)

STANDARD SEWAGE TREATMENT UNITS

NEW GENERATION PACKAGED SEWAGE

TREATMENT PLANT (NGPSTP)

• FLUIDISED MEDIA REACTOR (FMR)

• MEMBRANE BIO-REACTOR (MBR)

OBJECTIVE OF BIOLOGICAL TREATMENT

OF WASTEWATER

• Main objective is to remove organic matter from

wastewater in a natural way without using toxic chemicals

• Other objective can be to remove other than organic matter

such as ammonia/ heavy metals/ toxic organic chemicals

like cyanides, phenols, etc.

• ORGANIC MATTER in wastewater is measured in terms of BOD

(biochemical oxygen demand) or COD (chemical oxygen demand).

• BOD is defined as the amount of oxygen required for the biological

decomposition of organic matter under aerobic conditions at a standardized

temperature and time of incubation.

• COD is the amount of oxygen required for complete oxidation of organic

compound into carbon dioxide and water with the help of strong oxidizing

agents such as potassium dichromate.

TERMS USED IN BIOLOGICAL TREATMENT

BIOLOGICAL TREATMENT CAN BE

AEROBIC which requires oxygen for their activity

OR

ANAEROBIC which does not require oxygen and produces

methane as a by-product for possible use as energy
