On-site sodium hypochlorite generation system - maintenance profile
For more than ten years, on-site sodium hypochlorite generation has gained increasing acceptance as an alternative form of disinfection treatment in water and wastewater applications. De Nora ClorTec® systems generate a 0.8 percent sodium hypochlorite solution on demand by combining salt, water and electricity to provide a stable source of disinfection. While ClorTec systems are easy to maintain, they do require daily, weekly, monthly, quarterly and yearly maintenance to ensure operation at optimum levels.
An efficiency test is done at the start-up of any ClorTec® system. This testing confirms the performance levels (operating temperature, sodium hypochlorite solution addition, etc.) required for the constant production of a 0.8 percent sodium hypochlorite solution using set salt and power consumption levels. Following the manufacturer-recommended maintenance and service schedules after start-up will help to maintain the same efficiency levels, ensure compliance with warranty requirements and provide economic benefits to the end user.
When properly maintained, the equipment can be used for the full intended life, and unnecessary replacements and repairs can be avoided, leading to cost savings. Well maintained systems will experience less unplanned downtime, lessening the need to purchase a back-up method of disinfection and reducing the requirement of manpower to attend to unplanned maintenance.
Maintaining a consistent solution strength also is key to the overall performance – not only of a ClorTec® system, but of ancillary equipment used with the ClorTec® system as well.
