31. Sewer Bypass Projects Surge As Infrastructure Ages 2/18/2020

    Temporary bypass systems allow for necessary maintenance and repair. 

32. Digital Predictive Maintenance Drives Water Industry Productivity 11/19/2020

    The adoption of Industry 4.0 continues to gather pace, with industrial digitalization leading the way. The water processing industry in particular has seen a steady increase in digital adoption and the sector has in fact overtaken other industries. For example, water was one of the first industries to really make full use of predictive maintenance to extend the life of aging assets and improve operational efficiency.  James Chalmers, Vice President, Global Water & Wastewater Sales at ABB, outlines the advantages of this approach.

33. Article: Floating Horizontal Aerators Enhance Eufaula, Alabama Activated Sludge Plant 1/18/2008
    The Eufaula, Alabama, wastewater treatment plant (WWTP) is an extended aeration activated sludge facility designed for an average daily flow rate of 2.7 million gallons per day (mgd). Prior to February, 2005 this WWTP used vertical aerators to provide oxygen and mixing in its aerator basins. The plant has two aeration basins, each 1.87 million gallons in volume, which had 160 horsepower (hp) of vertical aerators in each basin
34. Hydra-Stop Solutions Isolate Damaged Valve During Water Main Replacement 6/3/2021

    The Village of Covington, Ohio had an ambitious 90-day project to replace the water main, taps, sewer main, laterals, and storm sewer through the center of town. Unfortunately, on day one, an unknown water service line was snagged and the top half of an 8” valve blew off, causing water to shoot 10”–12” out of the street.

35. Automating Stanley Consultants' Conceptual Design Process For A 1MGD Wastewater Resource Recovery Facility 8/22/2022

    The Transcend Design Generator helped Stanley Consultants to automatically ascertain the appropriate sizing requirements for a new Flow Equalization Basin and an extension to the existing Aerobic Digester. 

36. Water Stressed City Looks At Opportunities To Reuse And Recycle Tertiary Treated Municipal Sewage For Cooling Tower Application 9/23/2020

    Bengaluru, being a water stressed city, was looking at opportunities to reuse and recycle of tertiary treated municipal sewage for cooling tower application in a nearby power plant. Jakkur STP, being a 10 MLD plant based on conventional anaerobic + conventional activated sludge, was identified to supply about 15 MLD of recycled water for the power plant. The entire plant was designed and retrofitted as two process trains of 7.5 MLD. Read the full case study to learn more about why Integrated Fixed Film Activated Sludge technology (IFAS) was determined to be the best suitable upgrade.

37. Technologies To Meet Smaller Footprint And Stringent Nitrogen And Phosphorous Requirements 2/5/2020

    The Buxahatchee Wastewater Treatment Plant in Calera, Alabama was built in 1960. It upgraded in 1985 to a 0.75 MGD capacity extended aeration system with integrated clarifier and traveling aeration bridge for nitrification.

38. Get It Out: Effective Removal Of Inorganics 6/20/2020

    Modern wastewater treatment processes are not designed to operate with inorganic solids in the waste stream. While grinders are typically a cost-effective method for protecting the pumps at pump stations, there are other critical junctures within a treatment plant where operators have an opportunity to protect valuable assets with screening technology.

39. A 50-Year Partnership Leads To Successful HDD Installation Of 48-Inch AMERICAN SpiralWeld Pipe 3/14/2024

    When the Grand Strand Water and Sewer Authority engaged Ruby-Collins, Inc. to expand and upgrade its water and sewer system, Ruby-Collins President and CEO Scott Cline knew the job would be challenging – beginning with the project’s scale. A key feature in the upgrade was the installation of a 48-inch spiral-welded steel pipe water main that was coated in polyurethane and five miles long.

40. Comparing Sludge Removal Systems For Water Treatment Plants 5/12/2022

    Due to limited clearance and accessibility, effective removal of settled sludge beneath tube settlers has long been a challenge for plant owners and design engineers. They needed a sludge removal solution with a low-profile design that would offer flexibility during operation and maintenance.
