Even though carbon adsorption can be an effective treatment technology for removing organic compounds, such as PFAS, from water, it can be expensive or may not achieve desired removal objectives if improperly designed. Proper full-scale design of this adsorption process typically results from carefully controlled pilot-scale studies that are used to determine important design variables, such as the type of adsorbent, empty bed contact time, and bed configuration. However, these studies can be time consuming and expensive if they are not properly planned. To meet the need for planning effective studies and to help alleviate expense, EPA has signed an agreement with Michigan Technological University to make a series of adsorption models available to the public at no cost. This webinar will provide an overview of the series of adsorption models, along with examples of how they can be used to help design pilot treatment systems and provide a first-cut prediction of full-scale results. The information generated from the models will provide states and utilities with a better understanding of the fundamentals of carbon adsorption and what that means to the operation, performance, and costs associated with this technology.

This webinar is an opportunity to ask your questions and have our experts provide you the best answers we can at this time. Coronavirus has upended all of our lives in a very short period of time, but water utilities are affected in very specific ways. Water personnel must keep working as the continuous provision of water couldn’t be more vital. However, as others have been laid off or lost their incomes in one way or another, the utilities will be losing revenue and many will not be performing shut offs. What might this mean for water system finances? How will your water system handle a deficit? Many small systems have 1 or maybe only 2 people who are familiar with the system, including where assets are, how it operates, etc. What happens if personnel are not able to work due to coronavirus or something else, such as an injury? Does the utility have a good map or an Operation and Maintenance Plan to help another operator who may need to come in and help but is not familiar with the system or the location of assets? Does the utility have an asset management plan it can rely on to […]

 Communities are increasingly considering regionalized solutions for water system challenges regarding aging infrastructure, contaminated water sources, and capacity needs. In order to cover the basics of regionalization models, this webinar will introduce a couple of regionalization options while providing resources and advice on how to approach your partnership agreements in an effective and beneficial manner.
