Hi guys I was unsure where to put this question -- so here goes. I have something called an "ELMA" cleaning line, which has several vats for cleaning medical devices. The final vat is deionized water, which is fed from something called an "ELMApur85", which also employs UV-light for antimicrobial effect. I want to check the CFU count in the water in the final vat, but I cannot find anything regarding the limits of CFUs in deionized water - as deionized water is many things Is there a guideline or other official information that has 'real' numbers, or just a recommendation? Thanks for reading!
