    Printing Company Saves $78,000 in the First Year After Using G-C’s Expert Solution

    Written byKelle Zeiher

    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…

    A “Big-picture” View and ROI Analysis Shows That Spending a Little More Saves a Lot More

    Written bySean Robbins

    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…

    Water Treatment Programs That Work Where Other Programs Fail

    Written byJeff Jahns

    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….

    Improved Boiler Efficiencies and Reduced Waste Yields Substantial Savings in Site Resources and Operational Expenses in A Lumber Company

    Written byKelle Zeiher

    I. Challenges A lumber company in East Texas experienced high corrosion in their steam kilns resulting in expensive replace/rebuild costs. They were going through the following issues: II. Approach Garratt-Callahan’s team analyzed the site’s source water and kiln chemistry. They found that the company’s boiler water carry-over and high levels of chloride problem were due…

    Identifying and Resolving Reverse Osmosis Performance Issues in a Midwest Ethanol Plant

    Written byKelle Zeiher

    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…

    Empowering Gypsum Plant Staff and Restoring Reverse Osmosis Operation Efficiencies

    Written byKelle Zeiher

    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…

    Garratt-Callahan Helps a Hospital Save More Than $90,000

    Written byMike Scholnick

    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…

    Saving A Northwestern Particle Board Manufacturer’s Plant Operation by Solving RO Fouling Issues

    Written byKelle Zeiher

    Persistent reverse osmosis fouling threatened a particle board manufacturer’s productivity until Garratt-Callahan implemented a tailored water treatment program. By prioritizing proactive monitoring, the facility extended RO membrane life and significantly improved system reliability. This success proves that expert industrial water management is vital for preventing costly production downtime while maintaining rigorous, high-purity water standards for efficiency.
