This webinar features CAIROX® CR Potassium Permanganate Tablets as a unique controlled-release (CR) formulation that dispenses permanganate slowly into flowing water. CAIROX CR Tablets are a safe, easy-to-handle oxidant technology designed to treat odors in municipal and industrial wastewater at remote sites, lift stations, or where feed equipment is not practical. The CR technology is very fast reacting with H2S (on the order of seconds) and other organic odor-producing compounds, making it an excellent choice when retention times are very short. In the fall of 2015, a Midwestern Wastewater Treatment Plant (WWTP) with typical daily flows of three million gallons per day was receiving neighborhood complaints about strong H2S odors coming from gravity interceptors. This presentation will highlight the use of CAIROX CR tablets as a novel and cost-effective choice for H2S removal.
