The problem with PFAS waste incineration

The U.S. Department of Defense (DOD) released a memo placing a moratorium on the incineration of materials containing PFAS (per- and polyfluoroalkyl substances). According to the memo, the 2022 National Defense Authorization Act requires the ban until the DOD issues guidance implementing the U.S. Environmental Protection Agency’s (EPA’s) interim guidance on the destruction and disposal of PFAS. And, what does the EPA’s current interim guidance say about incinerating PFAS-containing waste? It is best summarized this way: “More research is needed.”

What you need to know about peracetic acid for water treatment disinfection

The many drawbacks of disinfection by chlorine in pre- and post-treatment applications has led to a growing interest in peracetic acid (PAA) as an alternative in some applications. PAA has a unique chemistry that is highly effective against bacteria and other contaminants. It does not form any known DBPs and has less environmental impact. Before substituting chlorine with PAA, it is critical to understand the chemistry, its applications, and methods of handling and dosing.

The new workforce is equipped to modernize water data management

Dealing with old technologies, unsupported infrastructure, and monolithic architecture is an unfortunate reality for many cities and agencies. These outdated systems not only leave organizations vulnerable to cybersecurity threats, they also create a management nightmare for IT teams. They require a lot of time and resources just to keep the lights on and are not appealing to the new generation of workers that are very much needed in the municipal water industry.

Chlorine gas container system

Preventing a minor chlorine gas leak from becoming a major one

Responding to a chlorine gas leak can be difficult with a room full of chlorine gas, and the advisable solution is to close all of the container valves and ventilate the room to reduce the chlorine concentration. Of course, by this time the amount of leaked chlorine gas may be significant, eliminating ventilation as an option. The event becomes a reportable incident, that now needs to be dealt with by first responders and reported to the appropriate authorities. Halogen Valve Systems Inc. designs and manufactures automatic emergency valve closure systems designed to enhance the safety of chlorine gas installations.

Sensors allow for immediate response to incoming raw water quality changes

With treatment plants, their raw intake source water quality can change rapidly and impact treatment performance. These water quality events are not typically caught by traditional sampling methods or sensors in time to be managed efficiently. Always on, low-maintenance water quality monitoring can provide better protection from incoming water quality issues by alerting operators to key events in real time.

Improving public health in the Arctic by providing a safe water supply

While preventing such waterborne infections remains a goal of improved access to high-quality water, access to adequate water quantity is also important for preventing “water-washed” diseases. These occur where personal sanitation practices, for example hand washing, can prevent transmission of diseases to other people. This issue has become particularly relevant during the current COVID-19 pandemic.
self-cleaning scraper strainers

Automatic scraper strainers protect critical membrane systems

Membrane filtration is a valuable, commonly used means of filtering water and wastewater. The challenge is that membrane systems are delicate and can be easily damaged by large particulates in the water. A pre-filtration step eliminates this risk by removing oversized suspended solids to prevent damage, eliminate unnecessary maintenance, and reduce the cost of premature membrane replacement.

Examining the basics of pump selection

Every pump application differs and with growing technology, there are dozens, if not hundreds of options to choose from for each application. However, there are some options that are much more efficient than others. Selecting the right pump will lead to energy savings, lower maintenance costs, process improvements, and a significant reduction in risk of system failure.
