PTMD Scrubber Improves Odor Control at Vancouver Island Wastewater Treatment Plant
|
From Met-Pro Corporation
The French Creek Pollution Control Centre treats wastewater from the City of Parksville and the Town of Qualicum Beach on Vancouver Island in British Columbia. Originally, the plant used the extended aeration process with aerobic sludge digestion for wastewater treatment. From 1995 to 1997, the facility underwent a major upgrade to accommodate the increasing population in the area. At the same time, the facility was converted to the more robust trickling filter/solids contact (TF/SC) process for treating the liquid stream and autoheated thermophilic aerobic sludge digestion (ATAD) for treating the biosolids. The 18 million litre per day plant achieved a very high quality effluent using the TF/SC process; however, odours became a problem. At a peak, the Regional District of Nanaimo, which operates the plant, received up to 40 complaints in a month. The District started adding iron (ferrous) chloride to the wastewater collection system in an effort to control odours, but odours and complaints persisted. Products & Services
Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere.

Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.

Baghouses and Depth Filters utilize air flow throw filter media (often in the shape of a bag) to capture particulate matter. Filter elements with pleated media and other porous materials (ceramics, glass fibers, etc.) are also used.
