WASTEWATER CASE STUDIES AND WHITEPAPERS
-
Navigating The Partial-Pipe Flow Challenge
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.

Here's To Microbrews And POTWs
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.

2nd Generation ATAD Provides Superior Treatment
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.

Textile Manufacturing
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.

For much of Michigan and Wisconsin, as well as northern Illinois, 2026 has been the wettest March and April on record. The region’s aging water infrastructure was never designed for the volume of water it is facing. That’s a troubling sign for the future, with flooding becoming more common as global temperatures rise.

Polyacrylamide (PAM) selection in industrial wastewater treatment is frequently reduced to a trial-and-error exercise, resulting in reagent waste, inconsistent effluent quality, and inflated operating costs. This article presents a structured framework for PAM optimization across three critical variables — ionic charge density, molecular weight, and coagulant synergy.

A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.

Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.

Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
