Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result.

In addition, many wastewater facilities can no longer produce odors without facing the consequences of either constant complaints, or fines from federal, state and local authorities. In addition to being a nuisance, these foul odors can pose a health and safety concern for the community, especially at high concentrations.

This is why Dr. Laura Haupert, Director of Research and Development at OMI Industries, offered this recent, and highly in-depth, guide for identifying and remediating foul odors in wastewater treatment facilities in Chemical Engineering Magazine.

In addition to providing a detailed analysis of all odor-causing compounds, Dr. Haupert discussed today’s most cutting-edge, eco-friendly odor control solutions. Here are some more insights from the article, which point to OMI Industries’ Ecosorb technology:

Finally, natural odor control solutions can fully neutralize odors, and are atomized or vaporized into the air. These odor-control products contain natural plant oils, food-grade surfactant and water, and are both safe for the environment and the local community. When the natural odor control product is atomized into the air, small droplets are produced that cover a large surface area and attract odorous gas molecules through electrostatic charges. The electrostatic charge also facilitates the attraction of malodor molecules to the droplet surface whereby they absorb into the droplet. Once the malodor is in the droplet, odor neutralization occurs. The malodor then either naturally biodegrades in the droplet or an acid/base reaction takes place, producing a non-hazardous organic-salt and water.

Natural odor-control solutions often use plant oils. These products have the capability of neutralizing a broad spectrum of odorous chemicals, including hydrogen sulfide, mercaptans, VOCs, ammonia and amines. These solutions can be atomized into the air at WWTPs via air atomization systems, hollow bladed fans or by vapor-phase systems. The air atomization systems use water and nozzles to atomize the product into the air. The nozzle system can be suited to most applications at a WWTP. The hollow-bladed fan system is a uniquely designed system that dispenses the product into the open air.
