Designed to bring practicality and ease to daily, personal sanitary needs, increasingly durable disposable hand wipes have been making a mess with wastewater pump stations. By Smith & Loveless, Inc.

Chlorine gas is the historical disinfection choice for municipal potable water and wastewater systems due to its low cost and ease of maintenance. However, the hazardous status of chlorine gas and its potential as a terrorist target are driving many facilities to consider alternative disinfection methods. The decision frequently comes down to a choice between commercial sodium hypochlorite delivered in bulk (hypo) and hypochlorite generated on site (OSG). The primary decision factors are safety, cost, ease of maintenance, and environmental impact.

Discover why U.S.-made ductile iron pipe leads sustainable infrastructure—crafted from recycled metal, fully recyclable, and engineered for long-lasting, circular water systems nationwide.

Discover how Aquapolo Ambiental tackled RO membrane biofouling with HOD™ UV technology, achieving 30-35% longer membrane life, reduced chemical use, and enhanced water reuse efficiency.

Would your wastewater treatment plant be able to function during a sustained loss of its aeration capabilities caused by a flood or natural disaster? What if a fire destroyed the blower house? Being prepared with a contingency plan for temporary low-pressure air will help operators prevent panic, avoid costly decisions, and minimize impact when a crisis occurs.

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.

Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

Toward the end of the 1980s, Professor Kazuo Yamamoto from Tokyo University gave a lecture to a skeptical crowd. His topic? Immersed hollow fiber membrane bioreactors. Since the day that first audience listened to the possibilities of MBRs, much work has been done to make membrane bioreactors a common step in the wastewater treatment process.  

To optimize the chemical dosage to precipitate phosphates from waste- water, an orthophosphate ion analyzer is used, equipped with a reliable sampling system. By Endress+Hauser, Inc.

For many utilities, large and small, hang-ups over new and innovative technology for infrastructure management often boil down to “How are we going to implement (or pay for) all of that?” Fortunately, a new approach to integrating existing GIS and asset data, Internet of Things (IoT) real-time data collection, powerful analytical software, and more is providing solutions to turn tough challenges into manageable solutions that are accessible on a subscription basis.

Siemens’ extensive portfolio includes various flow measurement technologies, such as Coriolis, clamp-on ultrasonic, vortex, and differential pressure meters, catering to a wide range of industrial needs.

There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

Read about the cloth media filter installations that have been operating in food and beverage wastewater plants for over 25 years.

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.

SensyMaster helps to improve the operating costs of the most cost intensive process in sewage plants: Aeration. High-measuring performance and state of the art technology helps customers increase plant efficiency.

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored.
