Ultraviolet light

[saphead]

I have talked to a local producer that uses a sap steady and he said that it made a huge difference in how often he had to clean his RO membranes.(for the better) If I remember correctly the sap passage is only about .100" wide, that's why there are multiple lights/sap passage chambers so the uv light can do it's thing.

I would be interested in asking him a few questions about it.

$3,200 will buy a LOT of RO soap.

I installed a UV light on the concentration line when I had my first homemade RO which was similar to the RO bucket. I found it didn't make any noticeable difference. I'd save your money.

Just another example of a manufacturer taking advantage of people who don't know, and it simply sounds good.

Save your money seriously, you'd be better off putting a silver spoon in your tank if you're worried about microbes

You will not kill 100% with a water treatment unit in a single pass. If you recirculate your main holding tank sap past a UV light (no matter what velocity or chamber thickness), it will kill bacteria and yeast. Right? Will it keep up with reproduction rates?

[DrTimPerkins]

If you recirculate through a UV unit designed for water treatment, and it is operating properly (it is clean, the bulb is good, and the flow rates aren't excessive), you will kill some of the microbes in the sap. However, you will also raise the temperature of the sap (by the pump and the UV unit), which has the negative consequence of increasing the reproduction rates of the microbes. Where you end up depends on the efficacy of the UV unit and the rise in temperature. Kind of the "two steps forward, one step back" approach at best.

it sounds like the old adage- get it boiled! remains the best rule of thumb....
