Rinse water standard limit for microbiological analysis
Hi. Anyone who knows what are the microbiological limits for rinse water in tanks (CIP) and what are the references? Thank you.
Hi Rener De Jesus,
A commonly applied test is to determine the presence of micro-organisms in the final flush water, but in this respect, it is important to realise that micro-organisms will usually always be present in mains and bore hole water supplies. The total count of potable water should not exceed 100 cfu/ml (colony forming units) with the absence of coliforms and E.coli in 100ml.
It is therefore necessary to analyse the flush water for any increase in micro-organisms during passage through the plant.

PS - the micro. limits above are probably derived from EC Directive 98/83/EC.
