After years of relying on an inflexible tracking process, A.P. Nonweiler introduced cloud-based remote monitoring technology to increase inventory transparency, save valuable man-hours, and minimize the risk of costly shutdowns.

Flow measurement is critical to effective process control and management, whether for municipal or industrial uses. Before you purchase a flow meter, there are a lot of factors to consider. Be sure to answer these questions before deciding on the type of meter to install.

Aging, inefficient aerated grit facilities at North Davis Sewer District’s (NDSD) treatment plant headworks not surprisingly caused the typical headaches of poorly performing headworks:  downstream process tanks filled with grit and process equipment wore much faster than it should. And not surprisingly, it became a costly hassle for plant staff with annual basin cleanouts.

A manufacturer of railcar bearings, wheels, and axles needed a wastewater system upgrade to treat for oil, grease, suspended solids, and dissolved metals in a mix of process water and storm water runoff. The existing wastewater treatment system in place at the facility consisted of a small equalization tank, traditional clarifier and sand filter. 

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.

The Kittansett Golf Club in Marion, Massachusetts is rated one of America’s 100 Greatest Golf Courses by Golf Digest Magazine.

Pressurized dewatering is typically suitable for sewer systems in outlying areas with no direct access to local gravity sewer lines. It solves ground water pollution problems by utilizing current pumping technology combined with modern trends in sewage removal.

Finding ways to improve everyday processes in more efficient and productive ways is an important goal for most companies. Many water and wastewater treatment facilities use sulfuric acid when pH reduction is needed, but face safety and process risks as a result. As an alternative to sulfuric acid, carbon dioxide (CO₂) offers several benefits. 

A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

Lower tipping and hauling fees, plant and site odor, processing times and more for the waste industries.

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

Of particular interest when it comes to bridges is the locating of pressurized water lines on and under bridge structures. Pressurized pipelines can present a number of unique challenges to the design engineer and utility owner.

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

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.

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

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.

There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.
