Fresh off TrojanUV being named manufacturer of the year by the WateReuse Association, Water Online caught up with Jennifer Muller, Vice President of Global Municipal Sales for TrojanUV at this year’s WEFTEC, to understand how ultra violet systems are being applied in the growing movement towards direct and indirect potable water reuse.
While it took a series of egregious bungles on several different levels to plunge Flint into the crisis, perhaps the most unforgivable lapse has been government officials’ negligent water testing.
This one's not on you, plant operators. Rather than a charge for utilities to aim higher in performance, the latest regulation to impact water treatment operations, as well as others, falls on equipment manufacturers — those who make pumps.
Name a contaminant, any contaminant, and chances are that the U.S. EPA’s new reference tool has you covered — or at least soon will. The recently revamped Drinking Water Treatability Database is set to include more than 200 contaminants, with detailed information on what they are, where they come from, and how to get rid of them.
The federal Lead and Copper Rule (LCR) is destined for changes attributable to hard times in Flint, MI, and the agreement from an EPA advisory council that lessons must be learned from the latest crisis.
For nearly a decade, public utilities that draw from surface waters have been contending with a developing regulation that is emblematic of the U.S. EPA and the systems under its charge.
This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.
When it came time to design a new wastewater treatment plant for Field, the seasonal rise in population during the summer months added to the challenge of meeting Parks Canada's stringent mountain effluent targets. The goal of the new wastewater treatment plant was to protect this pristine wilderness area by setting the effluent target as close as possible to the natural composition of the receiving water bodies. With this in mind, Parks Canada reviewed the latest in advanced treatment technology and opted for a membrane bioreactor system
Oil & gas production is often associated with extraction of large quantities of ground water. After separation from the hydrocarbons, such produced water (PW) requires further treatment prior to discharge or reuse.
Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters.
Tampa Bay Water’s state-of-the-art surface water treatment plant has provided high-quality drinking water to the Tampa Bay region.
This edition of Disinfection Digest discusses the discharge limit of peracetic acid (PAA) into the environment and the incorporation of dilution factors in the assessment of a site-specific, risk-based residual PAA concentration in wastewater effluents.
The Siemens Channel Partner in Oregon, has a customer from an engineering firm who also volunteers for Engineers Without Borders (EWB). The Portland chapter of EWB took on a project in Les Anglais, Haiti, to restore their drinking water supply system that had been disrupted in the Fall of 2008.
This report gives a brief outline of the general measuring methods. Further, it illustrates the possibilities and limitations of the direct UV oxidation, as well as which technical modifications were made to the monitoring instrument, AMI Line TOC, to improve the performance of the UV reactor and, therefore, the precision of the instrument.
In municipal and industrial wastewater treatment plants, sludge clarifiers are utilized to separate solids from the water treatment effluent system by introducing air and flocculants. This process results in the sludge rising to the top of the pond or tank and spilling over a weir into a separate collection area.
Providing large cities with drinking water is never an easy task. Outdated systems can cause problems such as leakages or contaminations.
