The City of Windsor in Ontario, Canada, owns and operates two wastewater treatment plants.
An independent Midwest refiner operates refineries in multiple states with a combined crude oil processing capacity of more than 500,000 barrels per day. The company recently approved a project to improve the safety of its plant and reduce its costs for nitrogen gas used for tank blanketing. Read the full report to learn more.
The reuse of industrial wastewater is becoming increasingly common because of water shortages, environmental necessities, economic incentives, government mandates, and societal desires. By David Christophersen, Technical Support Manager, Veolia Water Technologies
This paper discusses gas transfer theory and key factors of the process along with sample applications using the Dif-JetTM including; transfer of CO2 gas for pH neutralization of wastewater, for aeration and oxygenation, and for disinfection using ozone. By Gary L. Rogers, Ph.D., P.E., Applied Aquatic Engineering, LLC
The Auger Monster, manufactured by JWC Environmental in Costa Mesa California, incorporates a spiral lifting screw with patented Muffin Monster® grinding technology. The system combines the benefits of a fine screen with the high-flow capability of a bar screen so it’s easier to remove unwanted solids from the wastewater channel. By JWC Environmental
Throughout my time in the industry, the one question that always gets brought up is, “With all of the options and technologies available, what is the best way to measure water and wastewater flow?”
The water and wastewater industries face challenges at every turn — from population growth to strict environmental and financial regulations to downsizing. The complex nature of both industries puts a great deal of pressure on plant operators, who typically tackle tasks manually. Download this datasheet to learn how integrated automation software delivers improved reliability and flexibility throughout the entire operation.
As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. By Scott Rouse, VP Product Management, Sierra Instruments
Total nitrogen (TN) has become a compound of concern because of its impact on eutrophication on water sources. And as more states begin to set limits for TN, accurate testing becomes paramount. Unfortunately, multiple labs and variable test procedures can lead to disparities in final results. Many of today’s test methods are also time consuming, expensive, and even unsafe for lab technicians to use.
This paper presents the field data collected over a twelve month period at a municipal surface water treatment plant employing traditional clarification and filtration. The final effluent turbidity was monitored by the third party compliance turbidimeter, a Swan Turbiwell (Protocol Turbiwell) was calibrated quarterly just as the compliance turbidimeter, and a second Swan Turbiwell (Non-protocol Turbiwell) that was not calibrated.
