One of the most perplexing challenges that wastewater plant operators face is the need to measure the various sources of influent. For closed-pipe systems, the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement. The good news is that there is an emerging solution that measures flow in a less-than-full pipe.

In the late 1970s, a wastewater treatment plant (WWTP) in Tullahoma, TN, built in 1955, was overloaded and deteriorating.

Utility managers and operators rely on flow meters to provide critical information for process monitoring and control. They require and fully expect the flow data to be accurate and reproducible.

Ultrafiltration (UF) has been proven a key in wastewater reuse, but operators have struggled to keep up with repairs or having to replace older hollow-fiber membranes. Recent advancements in manufacturing have produced more durable membranes that accomplish the task at a lower cost.

There is a greater need to raise awareness for better sanitation, water reuse, and storm water solutions with better simple, low-cost, robust technology.

As local breweries grow in popularity, their initial focus on hand-crafted recipes can quickly shift to business realities such as the costs and logistics of process wastewater treatment. Publicly owned treatment works (POTWs), brewery owners, and consulting engineers all have roles to play in making that trajectory smoother for up-and-coming craft and microbrewers.

In a bold move to modernize its wastewater treatment, Bowling Green, Ohio, installed the state’s first second-generation Autothermal Thermophilic Aerobic Digestion (ATAD) system—ThermAer—in 2004. The upgrade expanded the plant’s capacity from 6 to 10 MGD and replaced an inefficient, odor-prone coarse-bubble aeration system.

Aging pumps at Jackson Energy Authority’s Rolling Acres Lift Station (Jackson, Tenn.) resulted in frequent clogging and outages that required costly maintenance and repair.

Transitioning to advanced purification methods like UV-hypochlorite oxidation allows municipalities to secure reliable, local water supplies. These strategies mitigate drought risks and protect coastal environments by transforming wastewater into a high-quality resource for reuse.

One of the United States’ newest dairy processing plants features advanced wastewater treatment technology that not only radically improves biomass recovery and effluent quality, but also harnesses green energy from waste streams to drive production processes and reduce its carbon footprint.

Precise pH control is critical in biomanufacturing processes to ensure product quality, consistency, and safety. This application note explores the challenges of pH management across bioprocessing stages and introduces Pulsafeeder’s NextStep pump as a reliable solution for accurate chemical dosing and process stability.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

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.

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.

Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value.

Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.
