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: 30% drop in system’s recovery 40% increase in […]
It’s Easy, Safe, and Simple! Many industries, especially food, beverage, and healthcare must ensure a highly efficacious program for the control of pathogens, bacteria, viruses, protozoa, fungi, and algae. Sodium hypochlorite solutions (e.g. bleach) have long been the go-to product for many disinfection applications. Chlorine dioxide, however, has many advantages over sodium hypochlorite and is […]
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.

Imagine taking a relaxing shower after a day of attending seminars and ending up getting sick instead. This could be a very real scenario in the upcoming days when many hotels and even hospitals open after a long shutdown. One potential reason? Legionella pneumophila.
Boilers are a necessary part of many establishments and can be found anywhere hot water or steam is required. Most facilities, from the ones that produce food to hospitals, require uninterrupted use of boilers everyday.
Proper treatment is important for maintaining maximum steam production and avoiding unnecessary offline time. It is well known that boiler water creates deposits on the interior surface of the machine. Deposits may vary from scale due to concentrated minerals to those created by corrosion products.This leads to problems ranging from loss of efficiency to condemning a boiler, especially in the low to medium pressure boilers.
Your Containers and Drums? For any cooling tower maintenance, scale control is crucial. Normally scale control is done using liquids that contain antiscalants and corrosion inhibitors. It is a good enough method, but hardly the most convenient. Adding chemicals to the cooling towers, especially the ones on the roof, can be tough. Furthermore, the drums […]
In any type of cooling system; open or closed, once through or recirculating, growth of microorganisms is a major hindrance. The available heat from the water, air, nutrients and the pH level create an ideal environment for rapid growth often results in biofilm and slime. Organizations like hospitals, data centers, factories and even large commercial […]
Garratt-Callahan Formula 9420 Operators and managers of industrial heating, cooling and ventilation water systems rely on water treatment to ensure heat exchange efficiency and to extend system life expectancy. However, operational changes or issues relating to treatment failures, corrosion, or scale formation may warrant cleaning. Water containing high amounts of silica, if not properly controlled […]
With the global pandemic and variants of viruses being spread via aerosolized and aspirated droplets, water safety is more critical now than at any other time in our global history. Waterborne pathogens found in water systems include building sprinklers, water features, fountains, and delivery pipes. Anywhere water is stored, left to sit, or is used intermittently, or held in pipes is subject to the creation of biofilms. These hard-to-remove biofilms allow the bacteria to grow and multiply in a protected shell until eventually released and is aerosolized through various point-of-use devices.
