Problem: A pump station near an elementary school and park in the Agua Special Utility District in Palmview, Texas, had significant odor complaints. The pump station had hydrogen sulfide levels above 200 ppm, creating odors to the point where the school would not allow the children to play in the school yard or park.
Solution: The municipality sought bids odor-control systems for four pump stations experiencing high hydrogen sulfide levels. The engineering firm considered biological and chemical injection systems and ionization technology. The Terminodour ionization system (Kusters Water) won the bid and was installed in 2018.
Result: The system reduced hydrogen sulfide levels to less than 2 ppm at the wet well and stopped the odor complaints. School children now can play in the park. The system also keeps corrosive gases from attacking and deteriorating the concrete inside the wet well. 864-576-0660; www.zimacorp.com
