WASTE RECYCLING
TECHNOLOGIES FOR REUSE AND RECYCLE OF TREATED WASTE WATER
1) REUSE: Using the treated waste water for multiple beneficial uses
2) RECYCLE: Redirected the treated waste water back into the same process
UNTREATED WATER PROCESS
TREATED WASTE WATER
RECYCLE
BENEFICIAL USE OF TREATED WASTE WATER
1. Agricultural irrigation
2. Land scape irrigation
3. Ground water recharge or ground water replenishment, salt water
intrusion control
4. Recreational or environmental uses(lakes,ponds,fisheries)
5. Fire protection, air condition
6. Industrial recycling or reuse( cooling tower, boiler feed, process water)
Factors in selection of appropriate technology
a. Composition of untreated waste water( chemical,physical,biological
characteristics)
b. Desired water quality and intened use of treated waste water
c. Cost of treatment
d. Availability of treated technology
e. Compliance with the strategy requirements
INDSTRIAL WASTE WATER
Oil and grease, organic chemicals, inorganic chemicals, metals (Fe, zn,Cd,Hg etc.)
Hydrocarbons, phenols, pesticides, pharmaceuticals, solvent, dyes etc.
