Drinking-water treatment plants use various forms of chlorine to inactivate pathogens, oxidize metals or metalloids, and provide disinfection residual for distribution systems. Concerns of safety for chlorine gas and high-strength sodium hypochlorite make on-site generation of sodium hypochlorite an attractive option. To that end, De Nora Water Technologies recently upgraded its popular ClorTec line, adding significant operational advantages and enhanced system efficiency to the practice.

The ClorTec DN Gen II electrochlorination system features several upgrades designed to offer even greater on-site sodium hypochlorite generation efficiency, easier operation, less maintenance and up to 50 percent footprint reduction. According to Bryan Brownlie, marketing director for De Nora Water Technologies, the unit continues a reputation of reliability and safety that the science has provided after more than 3,500 ClorTec installations.

“De Nora has always prided itself on its electrochemical expertise, as an innovator with more than 355 patents and 3,000 regional extensions,” he says. “The investment of time, knowledge, and research and development resources in these product lines is returning some exciting results.”

Upgrades to the ClorTec system include a design that allows the duty and standby units to be mounted on the same frame, saving up to 50 percent on the footprint. Other improvements include full access to every component, making operation and maintenance simple, and a liquid flow backboard that can be located anywhere in the building for additional flexibility. Systems generate a 0.8 percent sodium hypochlorite disinfection solution, a chlorine equivalent, using three common consumables: salt, water and electricity. Units range in capacity from 2 to more than 3,000 pounds per day, with systems engineered and offered to meet any specified application demand.  

New features ensure optimal performance and efficiency, including nonintrusive level switch and temperature sensor design, optional split flow technology, and water and brine flow controls. Additionally, Smart Monitoring technology and acid cleaning notifications allow users to remotely monitor, troubleshoot and control the operation of their system and provide operation and performance data remotely.

“We have been listening carefully to the market to create a compelling new offering for our second generation ClorTec DN systems, addressing the concerns and needs of operators and engineering contractors alike,” Brownlie says. “The launch of our original De Nora ClorTec DN generators in 2015 was just the first step toward this point, and the process is always ongoing.”
