The Valley East Wastewater Treatment Plant (Sudbury, Ontario, Canada) hired an engineering firm to evaluate three disinfection options including chlorination followed by dechlorination, ultraviolet (UV) light irradiation and VigorOx WWT II. Read the full case study to learn more.

Depending on the age and design of wastewater infrastructure, it is easy for screening performance at the headworks of wastewater treatment plants (WWTPs) to get caught between a rock and a hard place. With so many challenges, what can be done to reduce the high risks of performance inefficiency, costly maintenance, or outright equipment failure? Fortunately, next-generation bar screen designs are poised to address these issues.

We would like to invite you to Register for our upcoming Webinar to discuss how the Argos SBR is expanding options and opportunities for wastewater treatment. Ideal for municipal or industrial applications, the Argos SBR is comprised of the award-winning Aire-O Triton® aerator/mixer and a proven fixed decanter design, along with advanced controls and monitoring systems.

The 1.5 MGD West Carrollton Wastewater Treatment Plant in West Carrollton, OH came on-line in 1989 and today serves 12,000 area residents. The activated sludge facility produces an average of 200 wet tons/month of sludge that, following belt filter press dewatering, is spread on area farmland by a biosolids management company.

Vero Beach (population 15,220 in 2010) is a small but densely populated city adjacent to the Indian River Lagoon on Florida’s east coast. Many of the city’s approximately 1,500 on-site septic tanks and drainfields were failing, and the excess nitrogen, phosphorus, and bacteria were considered primary contributors of pollution to the watershed.

Los Alamos, NM, the former site of topsecret laboratories where government scientists developed the atomic bomb during World War II, is once again a town at the forefront of new technology.

In the semiconductor industry, ultrapure water usage can be in order of 2 to 4 million gallons a day. The entire ultrapure water treatment process is comprised of two segments: makeup water and a high-purity water loop.

Have you ever walked or driven by a lake covered with a thick scum that looks like pea soup? This could be caused by blue-green algae, a cyanobacteria (“cyan” means “blue-green”) that is frequently found in freshwater ponds and lakes. Cyanobacteria are often confused with green algae because both can produce dense mats that may smell bad and hamper activities like swimming and fishing. However, unlike most green algae, blue-green algae can produce cyanobacterial harmful algal blooms (cyanoHABs). The highly potent toxins they make, called cyanotoxins, can harm people, animals, aquatic ecosystems, the economy, drinking water supplies, property values, and recreational activities.

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.

Officials at the Jefferson Parish Sewerage Department approached the team at Digital Engineering to find a long-term solution for the odor and corrosion issues throughout the East Bank Wastewater Treatment Plant. 

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.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

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

In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

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.

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. 

Flex-Tend flexible expansion joints have a proven record of providing protection for pipelines subject to subtle or sudden movement. As with all products used in the water and wastewater industry, protection is optimized with the selection of the proper assembly incorporated into a sound design. This paper is intended to provide assistance in both of these areas.

This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.
