Four Maintenance Tips for your On-site Generation System

 

The COVID-19 pandemic has elevated the significance of proper cleaning and disinfection in the minds of consumers, and required facility managers and their teams to clean more frequently. This increases the need for solutions that demonstrate efficacy against target pathogens but do not irritate eyes or skin.

On-site generation (OSG) of cleaning and disinfecting solutions offers facilities numerous benefits, from meeting the demand for increased cleaning to reducing chemical shipments. Properly maintaining an OSG system is critical for consistently generating cleaning and disinfecting solutions within the proper efficacy ranges. The process is relatively simple, meaning that facility managers can quickly learn OSG system maintenance and train their employees with little downtime.

Keeping an OSG System Running Smoothly

The PathoSans® OSG system produces two electrochemically-activated (ECA) solutions: an effective all-purpose cleaner, PathoClean®, and a powerful disinfectant, PathoCide®, using only salt, water and electricity.

Here are a few important tips for maintaining the system:

1. Review salt levels daily.

There are two areas to check salt levels on the PathoSans system: the water softener and the brine tank. Checking the salt levels daily ensures the softener is supplying quality water to the PathoSans system. Checking the salt level in the generator or brine tank confirms the PathoSans system is producing high quality cleaner and disinfectant. For best performance, assure the tank is at least one third full. To see the process of checking salt levels in action, watch this video.

2. Monitor pH daily.

The pH levels of PathoClean and PathoCide indicate the stability, efficacy and quality of the solutions. The pH of PathoClean should be at least 11.5 and the pH of PathoCide should be between 4.5 and 6.0. Facility managers can monitor pH using a Hanna meter and record the results in a daily log sheet.

When testing the pH of solutions, wait 30 minutes after starting the unit to get the most accurate readings and use a separate, calibrated Hanna meter for each solution. To see the process of checking pH levels in action, watch this video.

3. Check Free Available Chlorine (FAC) levels daily.

PathoCide is a hypochlorous acid disinfecting solution, and it needs to meet a certain measure of free available chlorine to be optimally effective. The acceptable range of FAC is 165-200 parts per million of FAC, ideally close to 200.

This process also uses Hanna meters. Recording the FAC levels on a daily log sheet can reveal unfavorable trends and help determine when a service technician’s help may be necessary. To see the full process of measuring FAC levels in action, watch this video.

4. Flush the brine tank periodically.

The generator tank stores anything impure left behind in the process of generating solutions. As a result, it requires flushing out, ideally every thirty days.

To drain the brine tank, turn off the power. Turn the valve located on the back of the unit to empty the liquid into the drain. Before restarting the system, make sure the cold-water source is turned on. Close the drain valve, then turn the system power on. The brine tank will automatically refill and then begin producing solutions.

Take Full Advantage of OSG

The processes above become routine and second nature for operations accustomed to using OSG. For those just adopting the system, mastering the simple maintenance steps of checking salt, pH and FAC levels and flushing the brine tank can make cleaning and disinfecting more successful. Performing basic daily and monthly maintenance of the system allows facilities to maximize the benefits that OSG offers, including a simpler and more sustainable cleaning program.
