A 20 Year Look at Chemical Treatment Trains
This presentation will detail the past 20-year history of both Passive and Active Treatment Systems that implement Chemical Processes specifically as a water quality compliance tool. The session will detail how these technologies have evolved, their past successes, mistakes, and future challenges surrounding their deployment. The presentation will provide a synopsis of the different technologies used, what chemical additives & processes have been tested, what has worked vs. what has not, and what are the next steps for this industry. Among discussion topics we will define Anionic, Non-Ionic, and Cationic chemical processes that have been deployed in liquid, gel, sacrificial anode, gaseous, and dry forms. Results from case studies that target turbidity, pH, organic, and inorganic contaminate removal will be displayed. The presentation will compile data and photos from the entire United States but will be presented from a California-Centric viewpoint. To provide the attendees a general scope of where, when, and why these technologies evolved, where the industry is today, and the potential impact they can have on our physical environment. We will explore historical data, case studies, results, and determinations from CA Waterboards, WA State Department of Ecology, and Oregon Department of Environmental Quality from a 10,000-foot view. This presentation is not technology specific and will provide attendees with a basic understanding of treatment trains and land applied source control measures that include usage of these Chemical Additives.
Mr. Hromatka began his career in Heavy Civil Construction ranging from hydro-electric plants to large diameter fluid transmission lines up and down the west coast. In the 1990’s, as stormwater regulation increased, it became necessary to adapt new and innovative BMP practices that extended the work season to help large, multi-year projects meet timely completion metrics. Matt has spent the past 20 years working in the Industrial and Construction Services markets with a focus on chemical and non-chemical treatment solutions.
