Preference For Chlorine Gas For Disinfection Supported By Gas Leak Containment Vessels
The superintendent of an average 4 MGD activated sludge wastewater treatment plant (WWTP) reports that his preference for using chlorine gas as his most cost-effective option for primary disinfection has been further supported by enhanced management of gas leak risk.
“We are operating 24/7 within 200-300 yds. of residences, as well as a youth baseball complex,” noted Wayne Lee, Supt. of the City of Slidell, LA’s WWTP, “and we also have a high regard for the safety of our employees. We haven’t had any serious gas leak issues since the plant opened in 1984, and we have a trained hazmat team on call for emergencies, but we were pleased to be able to enhance that response insurance with cost-effective, on-site physical containment readiness.”
“That leaves us much better prepared for any off-hours event, when there would be only one plant operator, and it would take longer to assemble the hazmat team.”
