EPC works for effective and economical Thermal oxidizer packages & Incinerator plants for hazardous solid wastes, liquid waste, MSW, industrial & medical waste treatment and discharge clean gas to air according to global emission standard.
DWA has fabricated and supplied 2 Incinerator plants, 100kg/h, running 24 hour per day, for solid & liquid waste treatment in Lorestan & Mahabad petrochemical plants in Iran. All EPC has been conducted completely by DWA.
DWA Incinerator plant is based on cost effective, less investment of equipment ,and resource circulation plant. The plant is consisted of drum lifters, belt & screw conveyors, crusher or shredder systems, automatic feeding system, rotary kiln, post combustion chamber, lncoloy hot gas inlet tube, lncoloy quencher, bag filter, wet scrubber, induced draft air fan, stack, forced draft combustion air fan, NaoH chemical tank, liquid waste storage tank, water circulation tank, pumps, valves, electric & instrument systems, PLC automatic control system. According to hazardous classification by customer, explosion proof motors with auxiliary equipment are applied. Either fuel gas or diesel fuel is applied. All flue gas is met to international emission standards. Fabrication, test & inspection procedures is also followed to international standard. This plant can be applied to MSW and Medical waste treatment.
