Water and Wastewater Solutions For Industry

  1. Farm Community Effort Leads To Improved Drinking Water For Thousands 3/28/2018

    All communities depend on clean water and that supply of clean water depends on the actions of members in the community and outside of it. The small city of Kutztown lies within the Saucony Creek watershed in Berks County, Pennsylvania. The watershed is mostly agricultural, dotted with small family crop and livestock farms, and the activities on these farms affect water supplies near and far.

  2. Refinery Treats Groundwater Contamination While Saving Precious Facility Space 3/20/2020

    A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant.

  3. Grim 2022 Drought Outlook For Western U.S. Offers Warnings For The Future As Climate Change Brings A Hotter, Thirstier Atmosphere 5/26/2022

    Much of the western U.S. has been in the grip of an unrelenting drought since early 2020. The dryness has coincided with record-breaking wildfires, intense and long-lasting heat waves, low stream flows, and dwindling water supplies in reservoirs that millions of people across the region rely on. Heading into summer, the outlook is pretty grim.

  4. Utilizing Thermal Mass Flow Meters To Optimize Thermal Oxidizer Performance And Reduce HAP/VOC Emissions 3/16/2021

    Many processes in the oil/gas refining, specialty chemical production, solvents, paint, coatings and photoelectric industries generate hazardous air pollutants (HAPs) and volatile organic chemicals (VOCs), which need to be removed from waste, flue and tail gases before emission into the environment to meet clean air regulations around the world. In addition to removing problematic greenhouse gases, emphasis is placed on eliminating toxins that can be harmful to industrial workers and the environment.

  5. City Of St. Cloud Relies On Thermal Flow Meters For Digester Biofuel Co-Gen Power Process 8/13/2018

    The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.

  6. Water Quality Trading: A Necessary Tool In The Compliance Toolkit 2/9/2015

    New pollutants and water quality parameters are changing perspectives on watershed solutions.

  7. Supplemental Dissolved Oxygen 7/3/2024

    The use of hydrogen peroxide to supply supplemental dissolved oxygen (DO) to activated sludge and other biological treatment systems is well documented and has been successfully practiced for decades.

  8. Textile Manufacturing 10/29/2021

    The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

  9. Onshore Crude Oil Decontamination Using A Water Security Test Bed 11/6/2018

    Onshore crude oil production has increased in the United States over the past few years. Oil producers, specifically the North Dakota Pipeline Authority and the Bakken Shale field producers are transporting crude oil by rail and train to both the East and West Coast oil refineries. While rail tends to be one of the safer and more efficient ways of transporting crude oil, there is still a risk of a spill. Oil spills are threats to both ground and surface waters, which can ultimately impact drinking water.

  10. Circuit Board Cleanliness Testing 10/29/2021

    Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.
