Waste Water -Microbiological Constitient?
(OP)
I have a waste water analysis from a wheat plant that, besides all of the usual dissolved solids constituents, contains a line item for "Microbial ATP" in units of "RAL". the values range from 4800-5100 RALs.
What is this, what do these values represent, and are these values considered high?

When a cell dies, ATP production is stopped and the ATP which has been made is rapidly degraded. A measure of ATP is proportional to the number of living cells, including large and small cells. When there is no ATP detected, it is generally accepted that there are no more living cells.
Instuments that test for ATP are special luminometers that measure bioluminescence and express test results in relative light units (RLUs), so I am not sure as to your units being RALs unless they are being stated as some sort of relative absorption light (units) -- I'll do some checking on this.

Unless you want (need) a certain amount of ATP (microbes) in the sample source, and 4800-5100 is that range, I would think that any readings less than the 4800-5100 RAL would be fine as that would indicate lower amounts of ATP.

Or is the RLU unit similar to the concept or the NTU/JTU for the measurement of turbidity?
