C. Air/Water Pollution arising out of operation of Industries.
To take care of Dust Pollution during plant operation, 09 nos. of Dust Extraction systems have been installed at different location of the plant. Dust Extraction systems are designed to operate on auto mode and it will arrest fine particles form transfer points and fine dust particles will get separated as the gas will pass through bag filters. The dust collected on the bag filters will get collected in hoppers provided below the dust extraction system.
We have also installed Pneumatic Dust Evacuation System below the dust collecting hoppers which will facilitate in transportation of dust through pipes from hopper to Silo.
To avoid dust pollution during Kiln operation Electro Static Precipitator (ESP) has been installed in the flue gas path to arrest fine particles from the gas before going to Chimney. In addition to above we have also installed the following to take care of pollution & monitoring the parameters.
i. Wet scrappers have been installed below GCT & ABC.
ii. Gas Cooling Tower (GCT) has been installed to take care environment norms especially when Waste Heat Recovery Boiler will be down for maintenance.
iii. All belt conveyors have been provided with closed gallery to avoid dust pollution during storm.
iv. Opacity meter is installed on Chimney to have continuous monitoring of gas coming out from Chimney.
v. We are also installing ambient air quality monitor equipments at 03 (Three) location of the plant to monitor air quality on 24 hours basis.
To take care of water pollution we will be constructing robust setting and recirculation system. The clear water from recirculation tank will be used for dust conditioning and other miscellaneous work.
We have done extensive plantation work within the plant area.
