The
guiding principle is to first investigate Waste Reduction /
Pollution Prevention options & later to achieve required
degree of treatment for the waste by typically utilizing
combination of several processes or equipment at the least cost.
| Air Pollution
Management : |
Control of particulate & gaseous pollutants using systems
based on the following equipment :
* Cyclones
* Bag-houses
* Wet Scrubbers - Spray; Cyclonic; Packed; Ventury
* Adsorbers
| Hazardous
Wastewater Management : |
Systems are designed based on data & experience gained after
running pilot tests on actual wastewater.
The treatment would include combination of the following :
* Physical phase separation using -
Thin film evaporation
Distillation
Air / Steam stripping
Liquid - Liquid
extraction
*
Chemical treatment -
Neutralization
Precipitation
Cyanide
destruction
Chromium
reduction
Electrolysis
Ion exchange
*
Incineration with exhaust gas treatment
Incineration types include -
Liquid
Injection
Rotary
Kiln
Fixed
Hearth
