Managing Your Potable Water System During the Pandemic

The Federal and State mandated business closures and travel restrictions, due to the COVID-19 virus, have caused many businesses to reduce water flow in various complex building water systems. While the COVID-19 virus is not associated with building water systems, there are other pathogens and water quality issues that can potentially develop due to stagnant or reduced water flow in buildings. There may be [...]

Is Sludge Thickening Worth the Effort?

Most wastewater treatment facilities benefit from sludge thickening operations. However, determining if sludge thickening is worth the time and effort isn’t quite as simple. Understanding your facilities treatment process and implementing a solids management plan will help to simplify the answer.  Execution of a solids management plan will require the consideration of facility goals, available [...]

Water Management Programs Frequently Asked Questions

Incidents of human illness and fatality due to pathogens in industrial, commercial and municipal water systems are increasingly prevalent in the news. Although it is not required by law throughout the U.S., practicing a water management program in accordance with the ANSI/ASHRAE Standard 188-2018 demonstrates the value of a safe and healthy environment, as well as protects your facility from potential legal disputes [...]

Fat, Oil and Grease Caps, Oh My!

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 [...]

ANSI/ASHRAE 188-2018: Minimizing the Risk Associated with Legionella

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 [...]

How to Select Your Pilot Study Resource

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. [...]

When You Can’t Buy Your Biological System a Heating Blanket

For those of you who live in colder climates, winter temperatures bring a different set of challenges for biological treatment of wastewater. Microorganisms thrive between 77°F and 113°F; but for every 10° drop in temperature, the bacterial growth potential decreases approximately 90%. So, how do you ensure optimal system performance in colder climates? Increase your Return Activated [...]

Your Performance Index: Your Guide to a Quick System Check-Up

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 [...]

When to Replace Your RO Membrane

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 [...]

Your Performance Index: Should You Be Cleaning Your Filter Media?

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 [...]

Make Your Backwash More Effective With 4 Simple Steps

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 [...]

When Do You Need to Replace Your Filter Media?

Filter media has a typical life expectancy of 10 to 15 years. The life span of your media may vary based on your raw water quality and filter maintenance, as consistent maintenance can prolong the life of your media. Signs that you may need to replace your media are often indicated in your system performance. Has the performance of your system decreased? Has your contaminant removal rates declined? [...]
