Industrial and municipal wastewater treatment generates odour that can be strong, persistent, and a nuisance to employees, residents, businesses, and industries located near the wastewater treatment plant.
Odour is generated in varying degrees throughout the wastewater treatment process with the main Odour-generating areas being pump stations, clarifiers, digesters, aeration basins and sludge handling areas. The odour that is generally associated with this process includes hydrogen sulfide, ammonia, sulfur dioxide, mercaptans, amines and indoles.
Each plant has its own particular problem areas, all of which can be remedied with Dew odour control products at strategic points to manage these smells.
Primary Treatment
Hydrogen sulfide is a serious problem in wastewater treatment plants. Fogging systems installed at the bar screens and digesters solve the problem. In some cases, Dew odour control products can be diluted with plant water for economical operation.
Municipalities
The sewage treatment plant has to all loads of community and that is usually the local STP plant. Raw sewage is especially odorous and can present odour problems to plants that otherwise have their emissions under control. Simple Dew atomization systems positioned near the unloading point and vented or open downstream locations will provide simple and effective temporary Odour control as needed.
Bioreactors, Aeration and Activated Sludge
Because holding tank for activated sludge can be both large and uncovered, migrating odour can be a serious problem. Dew can work with you to select the appropriate odour control products delivery systems to neutralize the odour.
Food Processing Plants
Food processing facilities having their own wastewater treatment plants. Controlling odour becomes two-fold: the smells generated from the processed food along with those of the wastewater need to be removed. Dew odour neutralization products are approved for use in food processing plants and are also safe for the environment.
Process of Odour Control
Neutralization of foul odour by odour Control is the combination of several different actions. For an effective Odour neutralization a combination of below effects, depending on the source of the odour and its explained class is used.
Neutralization: The active mater in Dew odour Control initially targets the odour molecule. The special molecular structure of Dew odour Control locks the foul odour molecule and blocks its structure capable of stimulating the receptors in the nose.
Balancing: The fragrances of different Dew odour control formulas are chosen for their opposing characteristic to the targeted foul odour by that formula. These fragrances act like a jammer for the foul odour and in a meaning confuse the message send to the receptors in the nose by the Foul Odour. This makes a polishing effect by preventing the perception of the foul odour.
Settling: When Dew odour Control is applied by misting systems, the mist created captures the foul Odour molecules and slowly settles down. With this effect very similar to the effect of rain in the atmosphere, the air is washed by a mixture of water and Dew odour control agents.
Breakdown: Enzymes bacterial and other components in the formula of certain types of odour Control formulas completely break down the odour molecule.
As a result of the combination of these three actions especially combined for the type and source of the odour problem, the foul odour is degraded below the perceptible level for the human being.
In an industry where the goal is to create something pure from a previously impure source, choosing an environmentally friendly odour control solution is a natural choice. For more information about biodegradable Odour management solutions, contact Dew.
