krohne Why You Should Replace Differential Pressure Transmitters With Radar

Replacing DP transmitters with 80 GHz radar eliminates density errors, reduces maintenance, and simplifies installation — delivering safer, more reliable level measurement for modern wastewater systems.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Be There Without Being There – SITRANS Store IQ

    After years of relying on an inflexible tracking process, A.P. Nonweiler introduced cloud-based remote monitoring technology to increase inventory transparency, save valuable man-hours, and minimize the risk of costly shutdowns.

  • Flow Meter Selection 101: Not All Flows Are The Same

    Flow measurement is critical to effective process control and management, whether for municipal or industrial uses. Before you purchase a flow meter, there are a lot of factors to consider. Be sure to answer these questions before deciding on the type of meter to install.

  • Self-Sufficient WRRF Completes In-House Grit Removal Upgrade

    Aging, inefficient aerated grit facilities at North Davis Sewer District’s (NDSD) treatment plant headworks not surprisingly caused the typical headaches of poorly performing headworks:  downstream process tanks filled with grit and process equipment wore much faster than it should. And not surprisingly, it became a costly hassle for plant staff with annual basin cleanouts.

  • DAF System Effectively Removes 95% Of TSS For Railcar Bearing Manufacturer

    A manufacturer of railcar bearings, wheels, and axles needed a wastewater system upgrade to treat for oil, grease, suspended solids, and dissolved metals in a mix of process water and storm water runoff. The existing wastewater treatment system in place at the facility consisted of a small equalization tank, traditional clarifier and sand filter. 

  • Dual Mixers Overcome Stratification And Prevent Ice Formation In Concrete Tank With Baffles

    The climate in Southgate, Ontario, is considered cold and temperate with significant rainfall throughout the year. Temperatures in winter average around -10°C and can drop as low as -30°C to -40°C for brief periods of time, which can wreak havoc on the local water storage tanks and distribution piping. Read more to learn how the installation of PAX Mixers has kept the tanks free from ice and has shown an improvement in disinfectant residual levels.

  • CCD Technology Succeeds With Well Water Purification

    The Kittansett Golf Club in Marion, Massachusetts is rated one of America’s 100 Greatest Golf Courses by Golf Digest Magazine.

  • Pressurized Dewatering: The Economical Solution For Wastewater Disposal Problems

    Pressurized dewatering is typically suitable for sewer systems in outlying areas with no direct access to local gravity sewer lines. It solves ground water pollution problems by utilizing current pumping technology combined with modern trends in sewage removal.

  • The 3 Main Reasons To Use Carbon Dioxide For pH Control

    Finding ways to improve everyday processes in more efficient and productive ways is an important goal for most companies. Many water and wastewater treatment facilities use sulfuric acid when pH reduction is needed, but face safety and process risks as a result. As an alternative to sulfuric acid, carbon dioxide (CO2) offers several benefits. 

  • KLa Slot Injector™ Aeration System Assists Cheese And Whey Production Plant Solve Its Nitrogen Discharge Challenge

    A gourmet cheese, whey protein, and lactose production facility located in the Midwest had been utilizing a land application system for effluent discharge for over 40 years. Using a combination of ridge and furrow and spray irrigation, the plant had many years of success applying their wastewater to the land.

  • Wastewater Sample Savings From Test Treatment Program

    Lower tipping and hauling fees, plant and site odor, processing times and more for the waste industries.

LATEST INSIGHTS ON WASTEWATER

  • With the rise of water scarcity, environmental regulations, and corporate sustainability mandates, produced water treatment has become a strategic imperative for industries far beyond oil and gas. It is one of the fastest-growing segments in the water treatment industry, which has emerged as an amalgamation of environmental stewardship, regulatory compliance, and technological innovation.
  • People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
  • As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
  • The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
  • Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
  • While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
