Klorigen™ technology selected by Anchorage Water and Wastewater Utility for Its Asplund Facility

Electrolytic Technologies Corporation, a leader in safe water disinfection, has been selected by Anchorage Water and Wastewater Utility to supply and install an electrochemical disinfectant generator to replace pressurized gaseous chlorine currently used at the plant John M. Asplund Wastewater Treatment Facility .

Electrolytic Technologies Corporation (ETC), manufacturer of the Klorigen™ On-site Chlorine and Sodium Hypochlorite Generators (OSG), announced today that Anchorage Water and Wastewater Utility (AWWU) has selected ETC to supply and install for the Utility an electrochemical disinfectant generator at its John M. Asplund Wastewater Treatment Facility (AWWTF).

The Klorigen process is uniquely designed to produce disinfectant for use in the water and wastewater industry. The Klorigen™ system selected by AWWU will produce 5,000 gallons per day of disinfectant solution at a concentration of 12.5% (125 gpl) for long term storage and direct injection. In addition, the system will be designed for future expansion to 10, 000 gpd per day.

AWWU’s John M. Asplund Wastewater Treatment Facility is a primary municipal wastewater treatment facility which currently processes an average of 28 million gallons per day. Primary effluent is chlorinated prior to discharge to a marine outfall. It is AWWU’s intent to eliminate the handling and storage of pressurized gaseous chlorine currently used at the plant in order to deploy an alternative less hazardous and equally effective to disinfect the effluent stream.

Prior to awarding the contract to ETC, AWWU conducted a study to evaluate numerous alternatives, including UV disinfection, 0.8% and 12.5% sodium hypochlorite production onsite (OSG), shipping bulk sodium hypochlorite in trade strength solution as well as some other technologies. Due to the higher operating cost of other processes, the Utility elected to proceed with the procurement of the higher strength sodium hypochlorite (OSG) alternative offered by Electrolytic Technologies Corporation.
"AWWU’s selection process was both extensive and thorough and ETC is very pleased to be selected for this project," commented ETC’s President, Derek Lubie. "AWWU was seeking a highly reliable, intrinsically safe process that would be compatible with their current operations and capable of growing with their future expansion plans. The size of this Klorigen™ OSG incorporates all of the features of our larger ten to 20-ton systems, such as state-of-the-art controls and instrumentation without the hazardous cell maintenance typically required by 0.8% alternatives.”
Klorigen™ uses high grade salt and utility-supplied water to generate disinfectant solution at the point of use. Klorigen generated chemicals meet NSF/ANSI Standard 60 requirements and the process has been uniquely designated by the U.S. Department of Homeland Security as a “Qualified Anti-Terrorism Technology”. Producing water disinfection chemicals on site eliminates the hazards of transport, handling and storage of toxic chemicals. Due to its proprietary salt treatment process and low power consumption, Klorigen has the lowest carbon footprint of any electrochemical process designed exclusively for municipal applications.
About Electrolytic Technologies Corporation
Since 2001, Electrolytic Technologies Corporation has been the sole manufacturer of electrochemical systems that produce elemental chlorine gas and high concentration sodium hypochlorite, which are designed exclusively for the municipal water and wastewater industry. Klorigen systems currently installed range from 100 ppd to 20 tons per day of equivalent chlorine - either as elemental chlorine gas or NaOCl up to 15% concentration. Inherently safe Klorigen technology eliminates the potential for hydrogen gas explosions and the need for routine hazardous acid cleaning of electrolyzers.
