A Cost-Based Assessment Of Leading Grit Removal Systems
"How much grit is my grit removal system removing?” is becoming one of the more frequently asked questions at Water Resource Recovery Facilities (WRRFs) and wastewater treatment plants. The intrinsic problem of grit and its scouring activity means that efficient grit removal is fundamental for protecting and optimizing downstream WRRF treatment processes and equipment. Advancements in cutting-edge treatment technology, including membrane systems, and the critical need to maximize equipment investments places an even greater emphasis on effective grit removal.

Pile Cloth Media Filtration For Clean Utilities
Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

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.
