Industrial Bleach in Cooling Towers? 2

[TheDude75]

Trying to come up with a better system of killing the "bugs" in our cooling tower. A number of vendors all tout their chemicals - some are oxidizers, some not.

I mentioned just pumping industrial bleach, which is significantly cheaper than any of the other options, and have never gotten a straight answer from a vendor as to why it would NOT work to control biological growth safely inside our cooling tower.

Can anyone give me a "yea" or "nay" as to whether pumping industrial bleach straight into a cooling tower is a viable and safe alternative to the more expensive biocides available?

Bleach can be used. However there are some enviromental concerns. With organic compounds, ether extractable chlorinated hydrocarbons are formed. Some of these compounds are carcinogeneous. In Europe discharge limits are being placed on these components,these limits are quite low.(around 100 ppb)
