Emergency Water Supply Planning
According to the American Hospital Association, about 36.3 million people are admitted to U.S. hospitals each year. We don’t typically think a lot about the availability of a resource as basic as water in medical institutions. But when there is a natural disaster or an unexpected man-made event, the dedicated staff of these institutions have it top of mind. Most hospitals keep back-up generators to handle the power outages usually caused by hurricanes. They don’t necessarily maintain an alternative water supply in case a water main suddenly breaks, or the power outage from a hurricane lasts longer than their generator capacity.

BioLargo & Garratt-Callahan Partnership
BioLargo, a science and engineering company that invents and commercializes platform technologies to solve some of the most challenging environmental problems, has partnered with Garratt-Callahan (G-C). This joint project creates and develops a wastewater treatment product design to salvage usable water from commercial facilities wastewater streams. BioLargo already partnered with G-C and specifically wanted to leverage the existing relationship. G-C will receive 25-35 test units for solid separation, waste, and waste treatment in the project’s first year.

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

Empowering Gypsum Plant Staff and Restoring Reverse Osmosis Operation Efficiencies
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…

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