The EF-120-Q and EF-040P-Q modules extend the life of ion-exchange resins used in the production of pure and ultrapure water by utilizing a proprietary hollow fiber membrane that removes 1.7 times more Carbon Dioxide than any existing SEPAREL module.

Wastewater Treatment Double-Play Game Winner

While aeration and digester wastewater treatment systems are fundamentally different, they share common challenges when it comes to accurate air/gas flow measurement. Flow meters need to operate over a wide flow range, fluctuating from very high to low rates.

Sulzer's Aeration System Improves Wastewater Treatment In A Frozen Vegetables Plant

Learn why a WWTP recently decided to progressively replace the old surface aerators in the biological basins by optimally-adapted equipment.

Spotlight On Reclaimed Water Regulations: California

Technological advancements play a crucial role in shaping reclaimed water regulations, as new methods for treating and reusing wastewater emerge.

Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed

The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life — from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA Denite technology is treating 450+ MGD in the Bay.

Savings Helps MABRs Gain Traction In Municipalities

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.

White Paper: Hoffman Revolution Blower Continues Tradition Of Innovative Design The Hoffman U.S. Machinery Division was established in 1905 outside of East Syracuse, New York. The initial product was an exhauster for the dry cleaning industry — pulling a steam vacuum across the garments.

How To Optimize Flow Measurement For Process Efficiency

Busy municipal water engineers will find that the new Water and Wastewater Treatment Guide from Fluid Components International explains how to optimize flow measurement in 20 different municipal applications.

The Minimalist Guide to Water Quality Analysis For Biological Nutrient Removal

Nitrogen and phosphorus are two wastewater constituents that, together, pose one of the most high-profile threats for consumers and the environment. An abundance of these elements is what ultimately leads to the formation of toxic algae in surface waters, an environmental issue that regularly gains mainstream headlines and, in some cases, poses an acute health risk to consumers.

Achieving A Delicate Balance To Maintain RO Membranes

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.

Microbial Control In Cheese Making

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

Biogas Measurement From Wastewater To Power Plant

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.

Best Practices In Moist And Wet Gas Flow

The Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

Reducing Total Phosphorus In Water Resource Recovery Facilities

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.
