Anchorage Water and Wastewater Utility’s AWWU John M. Asplund Wastewater Treatment Facility AWWTF is a primary municipal treatment facility currently processing an average of 28 million gallons per day. Due to safety and logistical issues, the Utility wished to eliminate the storage of gaseous chlorine and deploy an alternative disinfection method that is safe and equally effective.
AWWU evaluated several alternatives to pressurized chlorine before awarding the contract to Electrolytic Technologies LLC and installing a state-of-the-art Klorigen™ sodium hypochlorite generation system. These included Ozone and UV disinfection, 0.8% and 12.5% on-site sodium hypochlorite generators, and bulk delivered commercial sodium hypochlorite. Klorigen’s advantages were apparent after the evaluation.
The plant has been designed to include a potential expansion that would double the system’s production capacity if required at a future date. The Klorigen™ process is uniquely designed to produce disinfectants for use in the water and wastewater industry. The Klorigen™ system selected by AWWU is capable of producing up to 2,250 kg per day of disinfectant solution at a concentration of 12.5% (125 gpl), for long term storage and direct injection.
About Electrolytic Technologies LLC
Electrolytic Technologies LLC manufactures on-site chlorine gas and/or high-strength sodium hypochlorite generation systems for on-site applications under the tradename “Klorigen™”. Fully automated Klorigen™ systems safely and cost-effectively generate chlorine and sodium hydroxide from brine for on-demand usage, eliminating the hazards of chlorine storage and transportation. Alternatively, the products can be combined in the process to produce high-strength sodium hypochlorite at up to 15 trade % (150 g/L) concentration, at costs well below those of commercial bleach.
