Protecting residential water access during emergency repairs is essential for municipal reliability. Advanced insertion technology creates permanent control points on live, pressurized lines, preventing large-scale service outages and boil-water advisories for thousands of residents.

Simple yet effective, variable area flowmeters continue to deliver reliable, power-free measurement, with modern upgrades enhancing their flexibility, durability, and role in today’s process systems.

Here are some insights on CFD technology, its specific use in wastewater basins, and inside tips on how to apply it to greatest advantage across a variety of processes.

If you’re in the business of managing a water system — whether drinking water, wastewater or water used for industrial purposes — a luminometer can make your job easier.

In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District). Now, the innovative water treatment program known as SWIFT — Sustainable Water Initiative for Tomorrow — is changing the lens through which communities and government officials view wastewater, drinking water, aquifer replenishment, and even fighting sea level rise.

An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.

Consider your wastewater treatment goals, and follow along with this article to learn more about how to work with your partner on an ideal MBR solution.

Environmental regulations and water scarcity have created a need for economical water treatments that increase reuse. This paper will review the new PPG membrane that has a unique composite single-layer microstructure that provides high-flux, excellent separation capabilities and exceptional durability to improve the filtration and recovery of industrial wastewater.

Tiny bubbles — less than 200 nanometers apiece, small enough to fit 5,000 or more side by side in a millimeter — are making a big splash in the venture capital markets, and in the media, too. Nanobubbles can destroy harmful algal blooms, purify contaminated water, rid irrigation systems of biofilm, and perform cleaning feats that are nothing short of miraculous.

Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

Any process plant constantly generates a high volume of status data. Today, this data can be extracted from the plant, stored, analyzed, and prepared to meet operator needs and lower marginal costs.

Tightening phosphate limits require high-precision monitoring to ensure compliance and economical chemical dosing. Refined photometric methods now offer superior accuracy at ultra-low ranges, providing the stable data necessary to optimize wastewater treatment processes.

Learn how a wastewater treatment plant in eastern Switzerland relies on the targeted use of flocculants to prevent sludge washout. 

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.
