Fats, Oils and Grease (FOG’s) can dramatically reduce efficiency, while increasing the operational costs of your wastewater treatment system. Food processing facilities often experience build-up of grease deposits or caps in their lift stations and piping. Below we have highlighted some possible system impacts of leaving FOG’s untreated and solutions to ensure optimal system operation. Potential [...]
Introduction In June of 2015 the ASHRAE Standards Committee developed Standard 188-2015, Legionellosis: Risk Management for Building Water Systems. The most recent updated document (188-2018) outlines the minimum requirements for the development, implementation and ongoing maintenance of a L egionella risk management program in new and existing buildings. The Standard is a culmination of several years of [...]
Santa Ana Pueblo, NM required an additional water treatment system to meet the needs of their growing community. After previously working on a project with Tonka Water, a U.S. Water Brand, and being impressed with the high level of customer service they had experienced, the Pueblo once again sought out the company’s expertise. Santa Ana Pueblo opted to pre-purchase the new treatment system for construction, [...]
U.S. Water Services, Inc.

How do you know if you need a pilot study? If you do need a pilot study, how can you ensure it will be effective? Pilot studies are often used to validate or optimize a treatment process or technology and can provide the data needed for process design or state regulatory approval. Because all water sources are different and respond differently to treatment, design should begin with a complete water analysis. [...]
The beginning of a new season is the perfect time to perform system maintenance. As many plant operators know, consistent system maintenance optimizes system performance, prolongs the life of your system and detects minor fixes before they transform into costly repairs. We’ve included a list of suggested tasks below to help you perform a quick system check-up. Filters Ensuring that your filters are [...]

On the surface, it might seem that knowing when to replace the membrane elements in a reverse osmosis (RO) system would be simple. In attempting to keep it simple, many companies will use one or more of the following guidelines for replacing their membrane: time, often after 3 years (the membrane manufacturer’s warranty period) an increase in the RO permeate conductivity, as related to their water [...]
Bridgeport, located in western Nebraska, had previously been able to pump water directly out of the ground and into the distribution system, without needing to treat the water. It was later discovered that the water contained elevated levels of uranium, requiring treatment. Uranium can be naturally found in groundwaters, slowly dissolved over time from soils and sedimentary rock. Uranium is also a by-product of [...]
Should you be chemically cleaning your filter media? This may sound like something that could be beneficial, but it may not be right for your filter. This is especially true if you have Greensand™ or Ironman Sand™ filter media. Greensand and Ironman media are coated with manganese dioxide which, when charged, oxidizes manganese as water flows through the filter. Unfortunately, chemicals that are [...]
By optimizing your backwash system, you can improve your overall filter performance and reduce backwash frequency, while cutting down on media costs and preventing excessive water usage. 1. We recommend increasing your backwash frequency if you are experiencing: Excessive headloss (debris buildup in media) Diminished effluent water quality 2. We encourage you to sample your backwash water on a [...]
