Wade, First, I was not discussing treatment of drinking water at all. HERC is not into that market. Second, I was not debating anything, merely trying to explain what they have and are doing with their chemistry. They do get into industrial water treatment, like for cooling towers, etc. I personally can tell you from my personal experience that it outdates everything else on the market that I have found. I have operated a cooling tower in which we shut off the bleed completely, started with fresh city water, added their chemistry and operated a full month with no additional chemistry and no bleed. The TDS got to over 50,000 and the system operated scale free. At the end of a month we drained the filthy water, refilled both water and chemistry and ran another month. We did this continually over a 2 year period and at the end the system was cleaner then when we started. The overall water conmsumption was reduced by (trying to remember) approx 60% because of no bleed. No Nalco, Calgon or any other company has anything available to equal this as far as I am aware of.
As for the sprinkler systems, maybe you flush your system, but that is NOT usual at all! most systems are filled and left stagnant for years. The real problem are sulfate reducing bacteria eating at the pipe and causing leaks and major repair cost, as well as water damage.
One building I know of in Phx estimated it was going to cost in excess of 5 million dollars to replace the sprinkler system because of MIC.
The last i heard they were trying to sue the city for introducing the bacteria to their system. <good luck to them!> HERC has developed a method (with thier chemistry) to clean these pipes, dissolve the tubers, kill the bacteria (with other chemistry), flush the system and return it to service...descaled and MIC mitigated.
