A New Platform For Safer Surface-Aerator Maintenance
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.

AVT™ EZ VALVE® Ensured The Water Kept Flowing At A Hospital
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.

The Challenges Of Combined Heat And Power Generation From Biogas
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.

Chromium Treatment
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.

Chlorine Measurement In Wastewater And Regulated Discharge Requirements
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

LATEST INSIGHTS ON WASTEWATER
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.

With the rise of water scarcity, environmental regulations, and corporate sustainability mandates, produced water treatment has become a strategic imperative for industries far beyond oil and gas. It is one of the fastest-growing segments in the water treatment industry, which has emerged as an amalgamation of environmental stewardship, regulatory compliance, and technological innovation.
