TASKMASTER® Helps Make Sludge Into Forest Feed
The Birmingham Wastewater Treatment plant in Kansas City, Missouri is an activated sludge treatment facility that processes 12.4 million gallons of wastewater a day. The facility processes and receives 21,000 dry tons of sludge each year, which is pumped to sludge holding basins. For the last few years, the facility, in partnership with the city, has participated in an innovative recycling project and sludge has played a major role. Its use as fertilizer on land adjacent to the treatment plant has begun to convert the area into forest. It appears to be an environmentally sound, cost effective solution to sludge disposal.

How Ultrasonic Sensor Technology Can Increase Processing Plant Efficiency
In today’s competitive business environment, which focuses on increased throughput, economies of scale and a healthy bottom line, accurate and reliable measurement is a key component. Monitoring production processes by installing a wide range of sensors including flow, level, temperature, and pressure is common and crucial to be competitive. Although there are many reasons why plant managers decide to install monitoring devices in their process, environmental and regulatory reasons dominate one side of the spectrum, whereas quality, process control and monitoring govern the other.

Why Measuring Hydrogen Sulfide In Wastewater Matters
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.

LATEST INSIGHTS ON WASTEWATER

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.
-
Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
