GettyImages-157593000_450_300 How To Choose Among Wastewater Screen Options

Wastewater screening isn’t one-size-fits-all. The right choice depends on flow, debris, and efficiency needs, with long-term performance and maintenance costs shaping the best solution.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Putting Your Sustainability Objectives Into Practice

    Organizations don’t earn Wall Street Journal recognition for being ranked ninth among the world’s most sustainably managed companies without a companywide commitment to embrace substantial operational changes. Here are examples of sustainability opportunities available in water treatment applications and how those opportunities can benefit utilities, water-consuming industries, consulting engineers, and construction contractors.

  • Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility

    A Leopold filter system helped save the North Columbus Resource Facility approximately 1,000,000 gallons of water per day that was previously used for backwash purposes.

  • Grundfos Solutions For Industrial Water Reuse

    Water is such a fundamental necessity for life that it is often taken for granted. In modern industrial societies, the water from every tap is expected to be so pure that we can drink it without a second thought. However, the reality is much more complicated. Mankind is becoming increasingly aware that fresh water is a rarity, and the process of water treatment is vitally importance to us all. This white paper is intended to introduce the reader to the many elements that constitute the water reuse process.

  • Case Study: Real-time Continuous Nitrate Monitoring Provides A Window On Nutrient Loading In Lake Pontchartrain Louisiana's Lake Pontchartrain Basin lies at the mouth of the Mississippi Delta and squarely in the sights of water quality experts from around the world. The Lake Pontchartrain Basin is an esturarine system that has been significantly disturbed by the construction of the Mississippi River Gulf Outlet in the 1960s as well as agriculture, logging and development in the area. The lake's increasing salinity and shrinking wetlands have garnered significant attention, as has the nitrate-laden water rushing past the basin through the MRGO just below Pontchartrain's southern shore
  • 8 Ways MBR Assists Your Utility In Emergency Response

    Whether it’s a hurricane, flood, fire, or extended power outage, the systems that sustain communities are often the first to be tested. And among all treatment technologies available, membrane bioreactors (MBRs) have proven uniquely resilient, helping utilities recover faster, maintain compliance longer, and protect the environment when stress is highest.

WASTEWATER APPLICATION NOTES

  • Optimizing Brine Flow In A Geothermal Power Plant

    Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.

  • 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.

  • 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.

  • Nitrogen-Reduction Treatment Systems For Long-Term Operations

    The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

  • Determining Biochemical Oxygen Demand (BOD) With Lovibond® OxiDirect

    The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.

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.
