Incinerator System with Zero Water Discharge
We have already written in our earlier blogs about our Common Hazardous Waste Incineration Facility running in our plant. We have also talked about the changes to the equipment configuration we have carried out from time to time, to keep pace with the newer regulations and requirements.
The present equipment configuration includes, apart from the two primary chambers with a common secondary chamber, liquid waste handling system, auto loading, gas cooler, bag filter, acid gas scrubber, ID fan, 30 meter chimney, semi-automatic de-ashing arrangement, PLC controlled electrical panel for fully automatic operation and Continuous Emission Monitoring System which is connected directly to the CPCB portal.
This system configuration is perhaps one of the very advanced types being used for hazardous wastes, which, apart from, releasing extremely low emissions, also ensures zero water discharge. The flue gas exiting the secondary chambers at a very high temperature is cooled down to around 200 to 250°C at the next stage with the entire water sprayed getting evaporated, thus leaving no water discharge.
The only stage where some water is recirculated is in the Acid Gas Scrubber. Here the water is practically free of particulates and only contains some acids. In any case, this water is continuously bled back to the gas cooler where water is evaporated and salts are captured by the bag filter.
The result, therefore, is ZERO WATER DISCHARGE from our system, which makes it VERY ENVIRONMENT FRIENDLY.
In fact, it is this aspect that catches the eye of visitors who come to our plant. They are able, not only to see a modern customised plant made by Haat in their premises, they are quite happy with the emission values and no water to dispose of.
