Design, Engineering, Manufacture, Supply and delivery of Bio-Trickling Filter system and Activated Carbon Filter with airflow capacity of 11,500 m³/hr. The system should be made of chemical-resistant special SG-CSM-ECR with PSR-4503 resin, suitable for outdoor installation. The Bio-Trickling Filter should be based on synthetic SULRED-L bio media and the Activated Carbon Filter media should be virgin coal-based pelletized catalytic carbon, water-generable up to 5 times with GRASP SULFONE media. The system shall comply with the statutory guidelines of CPCB and designed in accordance with VDI guidelines. The odour control system shall include the necessary instruments as below a) Pressure transmitters to measure the pressure difference across each system inlet and outlet in Bio trickling filter b) Level sensors at Bio-trickling filter. c) PH transmitters at Bio-trickling filter. d) Temperature measurement at inlet. e) H2S monitor to be provided at system inlet and outlet. f) Motorized valves at Bio-trickling filter inlet and outlet. g) Circulation pump in duty & standby mode with accessories. h) Mist eliminator . i) Spraying system with full cone nozzles for primary & secondary stages. j) Differential Pressure transmitters to measure the Pressure difference across the Activated carbon filter. k) Manual valves at inlet and outlet of Carbon filter. Sampling port valves at carbon filter.

Design, Engineering, Manufacture, Supply and Delivery of FRP Self standing type covering systems with required access points designed to withstand high H2S concentration and UV exposure to encapsulate the source tanks in odour emitting areas, FRP Ductwork (External &Internal) to transfer the foul air from source tanks to odour control system via Gas Extraction Centrifugal blowers designed with appropriate static pressure & fabricated in Stainless steel SS 316 grade or higher. These Gas Extraction Centrifugal blowers shall be Duty /Standby mode operated with frequency converters and supplied with required accessories for complete functioning of the system. The entire system will be managed remotely via PLC-based control panel equipped with an HMI for precise control of instruments and drives.
