Operators of lakes, rivers, reservoirs, and other waterbodies commonly introduce harmful chemicals and other compounds — such as antibacterials and bleach — in an attempt to rid the water of problems such as algae and toxins. However, with beneficial bacteria it is possible to achieve a balance in water or discharge by reducing phosphorus and other key parameters naturally, thereby eliminating or drastically reducing the food source for algae.

As local breweries grow in popularity, their initial focus on hand-crafted recipes can quickly shift to business realities such as the costs and logistics of process wastewater treatment. Publicly owned treatment works (POTWs), brewery owners, and consulting engineers all have roles to play in making that trajectory smoother for up-and-coming craft and microbrewers.

Cyanobacteria occur naturally in many water bodies, but when they multiply, they can form harmful algal blooms (HABs), which can increase drinking water treatment costs for communities and impact recreational areas such as lakes. To notify communities about potential HABs, EPA researchers created CyANWeb.

Orange County SWRF utilized Aqua-Aerobic Systems' products to upgrade aeration process, sludge processing systems, more aeration tanks, a three-pass, modified step-feed process and four large clarifiers with return activated sludge systems.

When it comes to metering water flow — drinking water or wastewater — full-bore mag meters offer many advantages. While the underlying technology based on Faraday’s Law of electromagnetic induction is shared among all styles of full-bore mag meters, specific implementations have impacts on longevity and accuracy. Here is what to look for when the time to choose arrives.

Faced with increasing costs for controlling hydrogen sulfide in its wastewater collection system, the City of Bakersfield, California commissioned an evaluation of its program in 2019.

In the last forty years, a quiet revolution has occurred in our industry. This revolution is the result of new generations of joint restraint products that make it possible to quickly and safely restrain fittings at bends, dead ends, tees, valves, and reducers without the need for concrete thrust blocks or tie rods. These joint restraint products turn the pipeline into its own thrust block. The key to utilizing these new products is the understanding and proper application of the pipeline restraint design theory.

Wastewater treatment facilities are subject to many different drivers for completing upgrades. Among the most prevalent drivers is a need to keep current with ever-changing, and increasingly stringent, environmental regulations. These regulations frequently require upgrading to tertiary treatment and the removal of BOD, TSS and Total Nitrogen.

Among the pump stations managed by Branford, CT, is a long-term problematic station located at Burban Street. There were two primary problems at this station: 1) clogging from modern day trash and raggy, stringy materials, and 2) fats, oils, and grease (FOG) from a nearby nursing home and restaurants, which accumulate and float on the water surface, resulting in a horrendous mess.

In the semiconductor industry, ultrapure water usage can be in order of 2 to 4 million gallons a day. The entire ultrapure water treatment process is comprised of two segments: makeup water and a high-purity water loop.

The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules.  The modules offer several innovative design features that enhance ease of installation, operation and maintenance.  This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.

UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

Level controllers have evolved to meet today’s environmental challenges and industry demands. Learn how they support improved process management and, ultimately, a better bottom line.

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. 

Pulsafeeder has secured a significant order for its NextStep series of stepper motor-driven metering pumps, specifically for use in advanced Reverse Osmosis (RO) applications. This deployment underscores the growing demand for precision chemical dosing in high-performance water treatment systems. The order includes NextStep NS1 and NS9 models, each selected for their unique capabilities in high-pressure and low-pressure RO environments.

We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.
