This webinar will provide wastewater personnel the basics about water and wastewater membrane treatment, encompassing reverse osmosis, nanofiltration, microfiltration, and ultrafiltration. The key features of each process will be discussed along with application examples. Membranes will be expanding into wastewater treatment, and this webinar can serve as an introduction to the technologies available in current facilities and future applications.
Prior to 2014, the City of Edina selected portions of the pipe network for replacement based on network age and repair history. Edina proactively searched for solutions that would lead to a more targeted pipe replacement program and support coordination with other infrastructure investments like road reconstruction.
Arsenic, iron, manganese, and sulfide (AIMS) are common groundwater contaminants that have serious concerns both aesthetically and from a health perspective. Well-established treatment processes — oxidation/filtration and coagulation/filtration — are the industry standard for treating these contaminants; however, innovative medias can provide many benefits that traditional technologies lack, such as lower capital and operating costs.
The impact of the Clean Water Act (CWA) on U.S. waterways and surface water bodies has been significant over the last 47 years and one that should not be overlooked. At its passing in 1972, on the heels of an oil slick catching fire on Ohio’s Cuyahoga River in June 1969, only 40 percent of the nation’s water was considered safe for fishing and swimming, not to mention drinking and other beneficial uses. Today, the percentage has reached 60 percent because of regulation.
This webinar will discuss two design configurations in MABR technology, as well as data on global installations, provided by Fluence. ASPIRAL is a prefabricated packaged biological treatment system ideal for decentralized wastewater treatment, eliminating the need for septic systems or piping to municipal lines. SUBRE is designed to retrofit existing plants to increase treatment capacity and optimize nutrient removal within a plant’s existing footprint.
Historically, organizations have done a very good job of collecting data, but a very poor job of understanding any of the data that was collected. This is changing. Come listen to the City of Salem, Oregon’s story about a cyanotoxin health scare in its finished drinking water and what the City is doing to prevent it from occurring again.
While implementing a pressure management system within a water distribution system might seem fairly straightforward, the experience of these three webinar speakers has been just the opposite. With so many factors affecting pressure, this one-hour event features three speakers — a water utility leader, a consultant, and a manufacturer — who share lessons learned as the City of Asheville transitioned from an underutilized, reactive water utility to an efficient, proactive one.
This on-demand webinar, presented by Harold Fravel, Executive Director of the American Membrane Technology Association (AMTA), covers membrane processes currently in use, including reverse osmosis, nanofiltration, microfiltration, ultrafiltration, and membrane bioreactors.
Our buried piping infrastructure can be 25 percent or more of the total asset value of a municipality. Inadequate attention to the proper asset management of this huge capital investment is putting many of our historic communities in jeopardy of becoming economically, environmentally, and socially unsustainable. Proper implementation of known asset management principals can help reverse this trend.
As pipeline infrastructure ages, utilities are on borrowed time before a failure occurs. The goal is to stay one step ahead of catastrophe by replacing high-risk pipe, while also finding and repairing pesky leaks that result in non-revenue water. With staff that is often limited, the best pipeline maintenance and asset management programs are the smartest ones. This webinar will cover the various options for condition assessment and pipeline diagnostics, the tools and requirements necessary for each approach, as well as the capabilities, benefits, and potential drawbacks to consider when choosing a method.
