Hydrogen Peroxide Injection Rate Adjustment Instructions
US Water Systems uses the "bubble method". This is a visual method that works best for quick and reliable H2O2 injection rates.
1
Set the proportional control on the Stenner injection pump to 50% by holding the "%" button while using the "UP" or "DOWN" arrows to adjust the % output on the tank mounted injection pump
2
Run water for 10 - 15 minutes
3
Take a sample after the catalytic carbon tank (or at a sink)
The water in the sample container (preferably glass) should be full of bubbles immediately after the sample is taken. It will look similar to an Alka-Seltzer dissolving in a glass. If not, the installer will adjust the pump to 60%, run the water for 10 - 15 minutes and check again.
4
Continue adjusting the knob "up" in increments of 10% and allow the water to run for 10 - 15 minutes between samples until the sample container is full of bubbles
Once the container is full of bubbles, it is an indicator that there is plenty of H2O2 in the water. BE SURE to allow 10 - 15 minutes between adjustments.
5
Now continue the same sampling process but decrease the knob setting in 5% increments, allowing the water to run for 10 - 15 minutes between adjustments until there are just a few bubbles in the sample container (20 - 30 defined air bubbles in the center of the solution in the glass) that come to the top of the water level and dissipate immediately
This should be the optimal H2O2 injection setting. The bubbles should be in the center of the glass and rise to the top immediately. Bubbles on the outside of the glass are not considered in the visual inspection. Bubbles in the solution is what to look for. This is an indicator that there is a small amount of residual H2O2 in the treated water and the contaminant is being oxidized. Once this setting is determined, the system will operate automatically.
Over the first 1 - 3 months, it is important to monitor the H2O2 level in the storage / solu- tion tank and start to gain usage data that will help determine the H2O2 usage and when to order replenishment H2O2 accordingly. This setting should be periodically checked and adjusted due to changes in the aquifer (well) and loss of H2O2 concentration by degradation. After 6 - 8 months, the H2O2 can lose concentration, so only replenish the tank to a level that can be used in 6 - 8 months to ensure the H2O2 concentration strength is consistent.
There is a tamper proof screw that can be installed in the cover when the H2O2 injection rate is set. This screw will fix the cover in place and prevent the pump rate control from being moved.
