Case Studies

Challenges The boiler – a 1000-hp tube unit – at a plywood manufacturing plant in the Pacific Northwest had scale so bad that it had to be shut down after only a year and a half of operation. Treatment chemicals for the boiler were being mixed daily, however, the feed system was not working properly….

Challenges Garratt-Callahan was the water treatment chemicals supplier for a Texas-based automotive parts manufacturer when the company opened up bidding on a new cooling tower as part of a major HVAC renovation at its plant. The bidding also included one company that was supplying the plant with processing equipment and services, and another that had…

Challenges Poor water quality at a Nevada printing company, with very high silica levels (67 PPM), limited the plant to running its boilers at a maximum of 10 cycles of concentration. Because it was difficult to control the high conductivity required, the system experienced frequent foaming and carryover, and energy costs were escalating. Approach Garratt-Callahan…

Controlled Release contains Garratt-Callahan’s proven, effective formulas, but in a concentrated and newly improved solid form. This will provide the same scale and corrosion protection for cooling towers as traditional liquid formulas, but with some unbeatable benefits. Go Green Garratt-Callahan Controlled Release products incorporate several aspects of the U.S. EPA Green Chemistry Guidelines. The products…

I. Challenges A northwestern particle board manufacturer committed countless hours to complete reverse osmosis (RO) cleanings, occurring at least once every month without seeing any improvement. This client was at risk of shutting down the boilers and the entire plant if they did not immediately rectify the situation.  Additionally, they were having trouble with their…

Challenges A college in Texas operates on an annual budget, and the purchasing policy is to award service contracts to the lowest bidder. One year that meant that Garratt-Callahan, the incumbent water treatment provider, lost the contract to a low-ball bid from a rival contractor. But at the college’s next yearly budget review, it was…

Challenge As a result of poor service and neglect from a series of water treatment providers, a healthcare center in the southwest had some serious equipment problems. Chillers were so heavily scaled that heat transfer was very inefficient and energy costs were spiking. Boilers were laden with iron deposits. All cooling towers had such massive scale deposits that…

Challenges To limit handling and liability issues, a medical center in the Midwest required hands-free delivery of its water treatment chemicals. But this requirement limited its product options and made it “captive” to a single supplier. The hospital’s water treatment capabilities were sometimes threatened as it waited weeks for overdue chemical deliveries. Approach An ROI…

I. Challenges A large municipal water reclamation plant on the Central California Coast that runs 3 RO trains had to switch to a low-cost, low-actives supplier due to a city-mandated bid process. After six weeks of working with the new supplier, the water plant experienced the following: If the situation continued, it would have resulted…
