Odor Control System

Dema&C has already for many years a range of sewage gas filters for odor emission control constructed in double wall, black UV resistant high density Poly Ethylene material. These filters are with integrated equipment such as fan and heater. Now Dema&C has designed a new range of sewer gas filters constructed in Glass Reinforced Plastic (GRP). Additional to the filters Dema&C can supply demisters, fans, heaters, etc. to fulfill client’s requirements.

Typical odor emission control applications are the removal of odor from sewage treatment plants. In these plants several emission sources need odor control equipment e.g. such as pump stations, wet wells, sludge dewatering and sludge trans-shipment operations from silo into trucks.

Sewage odor consists of mainly hydrogen sulphide. Next to hydrogensulphide the gas also contains organic sulphur components (mercaptans, hydrocarbons) and ammonia. In general activated carbon will adsorb all these components.
