The Challenges Of Combined Heat And Power Generation From Biogas
Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.

Domestic Wastewater Treatment In Telluride, CO
Last Dollar is a year-round residential community located just outside of Telluride, Colorado. The facility had been reliant on an aging treatment system that was failing quickly and needed immediate replacement to prevent operational fines. The current technology would not meet the new and more stringent effluent requirements in Colorado, so the project had to be completed quickly and within a tight budget. AquaWorks DBO provided the permitting and site engineering support to ensure the project was completed in 8 months from contract award to system operation.

Automated Solar Sludge Drying Frees Up Personnel
Solar dryers are fully automated to feed, move, and discharge biosolids cost-effectively. Even climate changes throughout the year are easily monitored and controlled to produce optimal output. Installation is very flexible with options to add components at a later date. Full automation means employees seldom need to enter the greenhouse and are free to use their time elsewhere.

How To Save Time, Save Money With Pilot-Plant Testing
When developing water or wastewater treatment processes for entirely new applications or modifying existing processes to accommodate changing water characteristics or regulatory discharge requirements, understanding capital investment, operating cost, and long-term performance is critical. Here are several ways to view pilot-plant or lab-scale testing as viable approaches to better outcomes with lower risks.

Using Drop-In Aeration Systems To Address Rising Oxygen Demands
Keeping pace with changing industrial wastewater treatment demands can raise multiple issues of oxygen demand, capital cost, and operating expense, often without the flexibility of taking basins out of service to upgrade to new levels of performance. Fortunately, there are alternatives for delivering more oxygen to treat more water.

Air Filter Maintenance: Impact On Efficiency And Machinery Health
In an ideal world, would we not want to eliminate air filters altogether? What keeps us from achieving this is foreign material, detrimental to air, which moves rotating equipment; meanwhile, the process that receives the air sometimes cannot tolerate it.
WASTEWATER APPLICATION NOTES

Reducing And Reusing Water In Steel Manufacturing
The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

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.

Microbial Control In Cheese Making
Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

Ozone output doesn’t guarantee performance. Learn how mass transfer efficiency determines how much ozone dissolves, drives treatment results, and impacts energy use and system design.

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.
