Hydrogen Sulfide Removal and Odor Control

Wastewater treatment is an increasingly important aspect of society as the practice of recycling water becomes more prevalent, and environmental regulations are progressively more stringent on effluent particulate concentrations.

Our business was originally founded on hydrogen sulfide removal and odor control in wastewater collections systems and wastewater treatment plants. As we developed our model of evaluating systems, developing and applying odor controls programs, and then effectively meeting treatment goals, our reputation has grown accordingly. Over the years we have refined our process and become a leader in delivering results that are widely trusted and respected in the industry.

We Go Beyond Odor Control, Phosphorus Removal from Wastewater and Other Treatments with Our Diagnostic Testing Services

In addition to supplying superior odor control, phosphorus removal from wastewater and other applications, we offer diagnostic testing services to determine the best approach for a given system. This allows us to understand the client’s objectives, and then work hand in hand to resolve the issues and do so at, or below, expected costs.
One tool we employ to achieve cost savings are Advanced Dosing Controllers (ADC’s) which are used to introduce the chemical into the system being treated. This allows flow paced dosing, which adjusts the feed rate to match the sulfide loading in the system. By carefully treating the actual cause, the community’s odor issues are resolved without excessive chemical treatment.

Pencco’s ADC technology provides the customer with online monitoring and control of each treatment point.
