After two years operation the plant reports that RoS2S Disk Thickener is consistently producing a 5.5% DS average with an ~0.6% DS average feed at a steady flow of 107 gpm (60 gpm activated, 7 gpm trickling, 40 gpm service water) running 24 hours a day.

It is increasingly difficult for municipal water utilities to provide seamless operations. Community growth, changing regulations, aging infrastructure, and extreme events are just a few of the challenges that need to be met. Remotely managing the key functions of water, wastewater, and stormwater operations in this rapidly evolving landscape — with the ability to act based on deep insights — underpins resiliency and creates a smart utility network.

Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.

Since many operators like to have results reported in a format that is familiar to them, it is possible to convert the gene copies/mL obtained from a qPCR reaction into an approximate cells/mL which is a calculation based on the average amount of gene copies per organism determined from literature investigations.

The Santa Clara Valley Water District in San Jose, CA, required additional water supplies to maintain regional economic vitality for its growing community. 

Nutrient pollution is getting worse in many estuaries throughout the United States, especially those on the heavily populated East Coast.

If a pump breaks down, it’s bad news because it likely means water is rising somewhere it shouldn’t. Yet paying someone to monitor your pumps gets expensive and drains precious labor resources. That’s where telemetry comes in

The climate in Southgate, Ontario, is considered cold and temperate with significant rainfall throughout the year. Temperatures in winter average around -10°C and can drop as low as -30°C to -40°C for brief periods of time, which can wreak havoc on the local water storage tanks and distribution piping. Read more to learn how the installation of PAX Mixers has kept the tanks free from ice and has shown an improvement in disinfectant residual levels.

Extreme weather and seismic threats are driving a new collaborative approach to infrastructure. By aligning utility needs with academic research and manufacturing innovation, providers can validate resilient technologies and deploy data-backed solutions for long-term reliability.

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

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

A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

Selecting the correct accessories will maximize cleaning while minimizing water use, tank refills, labor, and headaches.

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.

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

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. 

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide.
