WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Case Study: Jewett Elementary School The Mission Statement of the Rogue Valley Sewer Services of Jackson County, Oregon states: “It is the mission of Rogue Valley Sewer Services (RVS) to provide and maintain all sewer and storm drain systems within its boundaries, and provide customers with competent and professional services in the most cost-effective manner possible while maintaining the quality of life and the health, safety, and welfare of Rogue Valley constituents.” A key part of this endeavor was the Jewett Elementary School Project in the city of Central Point, OR
  • Green Lakes, WI, HeadCell Protects Downstream Processes

    The original plant in Green Lakes, WI, was built in 1983 and did not include grit removal. As a result, grit accumulated throughout the plant process tanks, particularly the aeration basin. This required periodic shutdown of the process tanks and hiring a contractor to vacuum the deposited grit from the tanks. The pending upgrade would include the use of an SBR treatment system as well as an upgrade to sludge dewatering. Plant personnel were concerned about grit settling in the process tanks, as well as grit wearing on the belts and rollers of the new belt filter press that would be used for sludge dewatering. The impact of these problems drove the plant to include grit removal in their upgrade project.

  • Monsters Protect Pump Station, Weather Storms In Scotland

    Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.

  • Union Township, NJ Automates Pump Station With TASKMASTER®

    Union Township, New Jersey was having a lot of trouble with their pump station. Although a small pump station, it was extremely cumbersome to maintain. The station was using a trash basket with a ladder and rail system to screen solids. This was extremely time-consuming, used an excess of manpower and proved to be ineffective at times. They knew they needed a better solution.

WASTEWATER APPLICATION NOTES

  • Enhancing Clean-In-Place (CIP) Systems With Pulsafeeder's NextStep Pump Technology

    Clean-in-Place (CIP) systems are critical for industries where hygiene and contamination control are mandatory—such as food and beverage, pharmaceuticals, and specialty chemical manufacturing. These systems automate cleaning through validated, programmed steps that ensure compliance with stringent safety and quality standards. This application note explores the challenges of CIP operations and demonstrates how Pulsafeeder’s NextStep pump technology addresses these challenges with precision, reliability, and cost efficiency.

  • Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water

    As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

If not adequately removed from drinking water, manganese can cause taste, odor and color problems, staining of clothes and plumbing fixtures, and incrustation of water mains that can result in black water at the customer's tap.

The DELUMPER® HV is a high-volume crusher that reduces agglomerated material with a one pass crushing action without overgrind or churning. This unit employs a heavy-duty cutting rotor with a heavy “V” shape bar cage. The HV design allows free-flowing material to pass straight through while directing oversize lumps and agglomerates to the crushing element to be reduced to size. The crushing mechanism employs no screen so maintenance is kept to a minimum. With its efficient design, the HV minimizes the motor size and power consumption.

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.
