I want to calculate the actual consumption of neutralite during neutralization treatment in a closed filter in order to know when to refill. I know how to calculate consumption related to aggressive water. But I would like to know if you've already measured the fines that escape during washing. Is it a negligible amount or should it be taken into account?
The consumption of neutralite during washes is negligible.
First of all, this is because a neutralite filter doesn't get cleaned that often. I recommend once a week, but in some installations the filter is only washed when it is refilled.
Second, any neutralite fine particles that are washed away are generally just impurities. In drinking water, the purity of the products used is about 97 to 98%.
Finally, in most cases, neutralite filters are not operating at peak efficiency. That is to say their efficiency is calculated based on their being refilled at 100%. But as soon as the water starts flowing, neutralite gets used up and the treatment quality is degraded.
