With so many different safety concerns — government-mandated or self-imposed — municipal and industrial wastewater treatment operators have a lot on their plates. Maintaining aerators used in open-basin treatment applications is just one source of those safety concerns. That is why a new approach to safeguarding worker well-being in the process of aerator maintenance activities is worth a closer look.

The duplex pump station at a Pennsylvania WWTP was upgraded with heavy duty solids-handling pumps, manufactured by Gorman-Rupp Pumps.

When a 40-year-old booster pump servicing Ochsner Health Centre in Baton Rouge, La began to falter, officials knew that had to resolve the issue fast. COVID-19 had left the hospital at full capacity so turning off the facility’s water was not an option. The pump’s existing control point was inoperable, so a new valve needed to be installed.

Recognizing pH's pervasive influence empowers operators to achieve consistent and reliable outcomes in every facet of water and wastewater treatment, underlining its indispensability for clean and safe water systems.

Unlock improved HVAC system performance by implementing modern pump retrofit strategies. Upgrading to high-efficiency pumps and smart controls significantly reduces energy use, lowers TCO, and enhances long-term reliability.

If modernizations in wastewater treatment plants are due, as a rule the permanently reducing limit values of ammonium, nitrate and phosphate are pushing the investment decisions.

Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.

When startup fails, check these four common culprits before you check anything else.

ABB provides an extensive selection of proven measurement and analytical products and solutions for power generation industry applications.

A U.S. light aircraft manufacturing company uses an alkaline cleaner followed by an alkaline de-smutter, rinse, acid de-smutter (possibly using potassium permanganate), rinse, alodine, and a final rinse. The three 1,700 gal rinses are dumped approximately once each week, or more often, based on the pH.

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

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

Siemens offers to our customers the ability to make both process measurements, and to remotely monitor the activity and health of instrumentation, whether you have a SCADA, PLC or DCS system, or not. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.

Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

This application note explores a test which demonstrated significant improvements in Oil-in-Water monitoring of industrial wastewater in comparison to the weekly grab sample analysis method.
