Success Stories & Case Studies in Water Treatment Excellence
A regional hospital partnered with G-C to improve water efficiency, reduce operational risk, and modernize critical boiler and cooling water systems. The project delivered approximately 5 million gallons in annual water savings, improved condensate recovery, and more than $100,000 in estimated yearly operational savings.
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….
I. Challenges A Midwest ethanol manufacturing plant replaced the membranes of their large reverse osmosis (RO) system but the differential pressures increased rapidly and exceeded the recommended operating ranges. If failure occurs, they will lose $200,000 in revenues per non-operational day. To cope with the problem, the ethanol plant carried out a Clean-In-Place (CIP) procedure…
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…
I. Challenges A large gypsum manufacturing plant had two reverse osmosis (RO) trains (A and B) but they were inefficient: Recently, neither RO train have been serviced with a complete Clean-In-Place (CIP) and the plant had a CIP skid available but they still needed additional support to use the equipment. Their current water treatment vendor…
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 high-volume beverage plant in Puerto Rico was processing well water at 85% recovery. The plant was performing monthly chemical cleanings and needed to replace the system’s 78 membrane elements every year. As a result: II. Approach Garratt-Callahan’s water treatment professionals began to troubleshoot the system. They uncovered a faulty check-valve that allowed…
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 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…
