Water Metering Supports Sustainable Water Management Solutions
Water Metering Supports Sustainable Water Management Solutions

The term “carbon footprint” has been on everyone’s lips since the start of the climate change discussion. Very few industries can claim that they play no part in impacting the carbon footprint — either for good or bad. This is also true for the water and wastewater industry that will have to take a closer look at increasing the efficiency of their facilities to reduce their carbon footprint.

WASTEWATER TREATMENT CASE STUDIES AND WHITE PAPERS

  • WWTP Reaches Clog-Free Operation With Self-Cleaning Impellers
    WWTP Reaches Clog-Free Operation With Self-Cleaning Impellers

    As with many plants modified for activated sludge treatment, the existing infrastructure at the Adams Field Wastewater Treatment Plant in Little Rock, AR, allowed rags and other debris to clog the impellers of the submersible pumps. One of the plant’s two 15-horsepower pumps was replaced with an 18-horsepower RAS submersible pump with a self-cleaning impeller, virtually eliminating the clogging problem by simply pumping away any debris that reaches the pump intakes.

  • The Straight Scoop On UPC/IAPMO Listed Grinder Pump Systems

    At least two major sewage grinder pump manufacturers advertise their systems as having UPC/IAPMO listings. There has been some confusion as to what this listing really means. By Kevin Clemons

  • Flow Data Red Flags: When To Act
    Flow Data Red Flags: When To Act

    Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

  • Demystifying Explosion Proof Submersible Pumps

    When the discussion turns to requirements for “explosion-proof” pumps, many people rely on word of mouth, past practices or even old wives tales it seems. By Kevin Clemons

  • How Ultrasonic Sensor Technology Can Increase Processing Plant Efficiency
    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.

    Denitrification Filters Meet Strict, Varying Nitrogen Limits

    The cities of Littleton and Englewood, CO, just south of Denver, share a wastewater plant — the Littleton/Englewood advanced wastewater treatment (AWT) plant located in Englewood. The 7886 m3/hr (50-mgd) Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. The facility also receives sewage from 21 districts within a 75 square mile service area. Plant effluent is discharged to the Denver metro area’s major watershed, the South Platte River.

  • Reduce SBR Maintenance Costs With Jet Aeration
    Reduce SBR Maintenance Costs With Jet Aeration

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

Capital Controls® Series 71P11A Gas Pressure Reducing Valve Capital Controls® Series 71P11A Gas Pressure Reducing Valve

The Series 71P11A Gas Pressure Reducing and Shutoff Valve is a diaphragm-type gas pressure regulating valve designed for use on chlorine, sulfur dioxide and ammonia gas service. The valve is used in a gas dispensing system to prevent liquefaction of the gas by providing a controlled pressure drop in the piping system. Downstream pressure is regulated to a reduced value by adjustment of the control setting. If the downstream pressure exceeds the pressure at which the valve is set, gas flow will be shut off.

FiltraFast™ Extreme-Rate Compressible Media Filter FiltraFast™ Extreme-Rate Compressible Media Filter

FiltraFast™ is a high-rate downflow gravity or pressure filter that uses a unique compressible media. The filter only uses hydraulic loading to create the required media porosity without any mechanical compressing devices. A proprietary backwash sequence enables maximum recovery, extends media life, and limits energy consumption. This process 1) significantly reduces the footprint compared to sand filters, and 2) reduces maintenance and replacement costs required by disc filters, and other compressible media filters.

3-Way Valve 3-Way Valve

The 3-Way Valve is available in 4”, 6” and 8” sizes and is available as a stand-alone valve or as part of a Vaughan submersible or vertical wet-well Chopper Pump. The valve is a non-plug design using a rotatable CD-4MCu valve disc to allow discharge out of either of the top ports.

  • Can We Turn Sewage 'Sludge' Into Something Valuable?
    Can We Turn Sewage 'Sludge' Into Something Valuable?

    Over the past few years I have become an academic expert in “sewage sludge” — the residual, semi-solid mix of excrement packed with microorganisms that is left behind within wastewater treatment plants. Every year the UK alone produces approximately 1.4 million tons of the stuff. About 80 percent of it is spread on fields as manure, but this still leaves us with a headache — what do we do with the rest?

Because Mount Ararat is cited as the place where Noah’s Ark came to rest after the Great Flood (Genesis 8:4).
