  2. How One Company Created An Easy, Affordable Way To Stop Damage From Wipes 12/22/2020

    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?

  3. Safe, Energy Efficient Disinfection For 45 MGD Combined Sewer WWTP Improves Water Quality 2/14/2017

    The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.

  4. Using Bubbles To Reduce Toil And Trouble 9/17/2024

    Two innovative products leverage natural fluid dynamics, biology, and aeration principles to reduce labor and energy consumption in wastewater applications — the Lagoon Master Aerator and the Wet Well Wizard.

  5. The Advantage Of The AERZEN Air Bearing Technology 3/7/2017

    The air foil bearing, allowing operation without the need for lubrication and maintenance, provides minimum life-cycle costs for the entire unit. Filtration is the only preventive maintenance which is necessary. The production costs of the complete assembly are very low due to the less expensive bearing technology in comparison to turbo compressors made with magnetic bearing this is a significant benefit in addition to reduced cost of eliminating necessary ancillary components such as bearing controllers, additional electrical filters and uninteruptable power sources.

  6. How The Industry Can Take On Wipes In The Waste Stream – And Win: Part 2 9/9/2015

    This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.   

  7. City Of Fayetteville Replaces UV Treatment System With BlueInGreen's HyDOZ Solution 2/1/2021

    After researching different ozone systems, plant officials ata 12 MGD wastewater plant in Arkansas chose to install BlueInGreen’s HyDOZ technology in order to more efficiently meet current permit requirements, as well as prepare for future legislation.

  8. Sturbridge POTW: Greater Capacity For High Flow Events, Enhanced Clarification For New Regulations 12/16/2014

    Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

  9. Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber 4/16/2014

    The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.

  10. FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey 9/11/2018

    Despite the destruction of Hurricane Harvey in August 2017, Duperon wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.
