Alaskan Utility Selects Electrochemical Disinfectant Generator to Treat Wastewater

System will produce 5,000 gal per day of disinfectant solution for long-term storage and direct injection

Electrolytic Technologies Corp. (ETC), manufacturer of Klorigen onsite chlorine and sodium hypochlorite generators, announced that Anchorage Water and Wastewater Utility (AWWU) in Anchorage, Alaska, has selected ETC to supply and install 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 system selected by AWWU will produce 5,000 gal per day (gpd) of disinfectant solution at a concentration of 12.5% for long-term storage and direct injection. In addition, the system will be designed for future expansion to 10,000 gpd. 
 
AWWTF is a primary municipal wastewater treatment facility, which currently processes an average of 28 million gpd. 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. Due to the higher operating cost of other processes, the utility elected to proceed with the procurement of the higher strength sodium hypochlorite alternative offered by ETC.
 
"AWWU’s selection process was both extensive and thorough, and ETC is very pleased to be selected for this project," ETC President Derek Lubie said. "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.”
