    Softening vs pH dosing of cooling towers

    Neither option is good for the environment. We have dealt with both soft water treated towers and acid feed as methods to boost cycles of concentration. Soft water fed towers causes a corrosion nightmare and also tend to get heavy salts of evaporation on the fill from the sodium in the soft...

    Handheld Meter Recommendations

    I was considering the Oakton pH/Con 10 water proof meter or the Myron L Ultrameter 6P. Has anyone tried these?

    Handheld Meter Recommendations

    I'm looking for recommendations on a digital handheld meter providing conductivity, pH, and temperature for field use. The meters we are using now are expensive to repair and are not waterproof. Their exclusive distributor network also keeps the purchase prices high. Any recommendations...

    Corrosion of steel adjacent to cooling tower

    We have seen significant corrosion around cooling towers when the towers had been treated with liquid bleach as the oxidizing biocide. Relatively new piping within approximately 50' of the tower had been corroded on their exterior surfaces, which had been painted when initially installed...

    "Magic" water descalers?

    Last spring our local community college district installed two identical Evapco cooling towers at one of their campuses. One tower is using a non-chemical "pulsing power" system for water treatment and the other tower is being treated with traditional chemical treatment...

    Use of Bromine in cooling tower systems.

    Glen, Bromine is the better oxidizing biocide in cooling tower applications because of more favorable dissociation curve in the pH 8+ range of cooling towers. Typically the products are used together for the best results since the chlorine helps to activate the bromine. We use a tablet form...

    Grease Trap Odor

    Check out the following paper on grease traps: http://members.aol.com/jitdsm/sas/Lowry_Paper/lowry.htm We use a biocatalyst to treat a restaurant grease trap in the Sacramento area. They to had been experiencing odor from the grease trap prior to treatment. The hydrosulfate off gassing even...
