WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Topeka WTP Installs Integrity A-758 PLUS™ Lime Slaker System To Replace Existing Lime Slaker

    The Topeka Water Treatment Plant (WTP) — a 60 million gallon per day facility - serves Topeka, Kansas and surrounding areas. Built in 1945, the plant underwent several renovations with the most recent upgrading the plant to its current capacity in 1993.

    In 2015, plant officials decided to replace the first of the existing slakers and, after considering offers from several slaker suppliers, chose the A-758 PLUS™ paste-type lime slaker manufactured by Integrity Municipal Systems, LLC (IMS). Read the full case study to learn more.

  • Why It's Time To View Plastic Pipe In A Whole New Light

    Because recent advances in plastic materials and processing have led to a new generation of plastic piping systems to handle challenging water and chemical environments, it is important to understand why some older piping choices might no longer be the best bet. Here are some key reasons to consider new plastic-piping choices for municipal and industrial water/wastewater applications in a whole new light.

  • Simplifying The Wastewater Treatment Train With A Stand-Alone Solution

    Explore how you can replace the operational troubles of many discrete water treatment technologies with a single modular unit, earning major savings on capital and footprint.

  • How One Company Created An Easy, Affordable Way To Stop Damage From Wipes

    Toilet paper. The most essential product necessary to life besides food and water. Also cited as the first item to run out at supermarkets during an emergency. For those who live in disaster-prone areas, keeping a stockpile is normal. But for everyone else, a few extra rolls of toilet paper is just a routine part of a grocery trip. So what happened when families everywhere panic bought toilet paper to get through an extended lockdown?

  • Unseen Infrastructure: The Underground Networks That Keep The World Turning

    In this article, read about the importance of unseen water infrastructure and the need for investment and maintenance. Explore the processes and challenges involved in delivering clean water and managing wastewater.

  • Best Practices For Equalization Tank Maintenance

    Membrane bioreactor (MBR) systems represent a sophisticated technology in the domain of wastewater treatment, offering superior effluent quality through an integrated process of biological degradation and membrane filtration.

  • Z-92® Uranium Treatment Process - City Of Lawrenceville, Georgia Case Study

    This uranium removal pilot study was conducted for the City of Lawrenceville, GA at their Ezzard Road Well No. 3 treatment facility. The City of Lawrenceville's water system contains concentrations of uranium and gross alpha that are in excess of the maximum contaminant levels (MCL).

  • Aeration Considerations: What To Know Before You Buy

    Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.

  • Disk Thickener Technology Replaces Gravity Thickener, Improves Performance Of Digester

    After two years operation the plant reports that RoS2S Disk Thickener is consistently producing a 5.5% DS average with an ~0.6% DS average feed at a steady flow of 107 gpm (60 gpm activated, 7 gpm trickling, 40 gpm service water) running 24 hours a day.

  • Case Study: New Option For Stormwater Treatment Maximizes Usable Land Area For Redevelopment In June 2002, First Independent Bank of Vancouver, Wash., began construction on its 15,000 square-foot First Investments Plaza office complex.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

Since 1969, Aqua-Aerobic Systems, Inc. has led the industry in surface aeration and mixing with thousands of installed units throughout the world. For those wastewater applications that require an efficient means of introducing oxygen into a system, the OxyMix pure oxygen mixer is an economical solution compared to other pure oxygen devices.

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

Combat odor and corrosion problems in your collection system with BlueInGreen technology. Designed to eliminate sulfide production by promoting an aerobic environment, our odor control solutions offer an effective alternative to chemical treatment in force main and gravity sewers. 

BlueInGreen odor control solutions are designed to eliminate sulfide production by promoting an aerobic environment, an effective alternative to chemical treatment. 

At Brentwood, trickling filters are often referred to as the “biological treatment workhorse.” By optimizing surface area in a given volume and maintaining the structural integrity required for deep towers, Brentwood media provides an ideal environment for microorganism growth.

Ranked among the industry’s most innovative solutions, the light and compact AVT EZ Valve is designed with a built-in isolation gate that allows the valve to be installed under pressure, a design feature that permits flow through the line while the repair is being made.

The TrojanUV3000®B is a simple, yet robust system designed for small wastewater treatment plants that are looking to treat 1 – 5 MGD (158 – 789 m3/hr). The system is straightforward to use and requires minimal operator involvement thanks to its modular design and proven components. It can be easily retrofitted into existing chlorine contact tanks and effluent channels, and comes pre-tested, pre-assembled and pre-wired to minimize installation costs.
