A portrait of John Paccione.

Dr. Paccione is an assistant professor in the Department of Environmental Health Sciences with a joint appointment in the Department of Environmental and Sustainable Engineering. His current primary appointment is as a Senior Engineer, in the Bureau of Water Supply Protection, at the New York State Department of Health (NYSDOH).  His research focuses on the modeling of processes that involve fluid flow including reactor hydraulics, multiphase flow (gas-solids and liquid solids systems), process development, and recreational water engineering.

At UAlbany, his work focuses on the application of engineering to water treatment methods to improve both efficiency and the analysis of treatment processes. He teaches fluid mechanics and portions of a course that explores and relates how water quality affects public health.

Dr. Paccione has five patents awarded and one under review as of (2022). The most recent patent (under review) is focused on a treatment system that can be used for removing and destroying low-concentration contaminants found in water. The system can be scaled over multiple orders of magnitude of flow and is based on established multiphase reaction engineering principles.


Sample of Activities at UAlbany

  • Development of a simple computational formulation for determination of disinfection compliance with the US EPA Surface Water Treatment Rule. This work applies fundamental chemical reactor principles such as residence time distribution theory. This work can be applied to the disinfection of drinking water as well as to wastewater treatment for potential reuse applications.
  • Spray grounds have become an attractive aquatic venue for children as they provide significant entertainment with little or no drowning hazard. However, the patron-to-water ratio is low which presents a significant water treatment challenge. As a result, a novel approach to water treatment was developed and embodied as a code regulation (Subpart 6-3 of the New York State Sanitary Code). An overview of the treatment design and development was memorialized in a publication to provide students and water treatment professionals with a means to better understand the rationale behind the design requirements.
  • Development of a method for determining the solids mass flow rate in a gas-solids riser using three physically relevant and readily measured parameters. The results of this work can be applied to process engineering systems where it is important to determine and control the solids mass flow rate of granular solids that are being conveyed pneumatically. Applications include solids drying and roasting as well as process control and equipment design.
  • Development of a means for controlling the conditions in a riser by specifying two of the three following parameters: solids mass flow rate, solids fraction, and particle velocity. This control technique is important for conversion processes such as regenerating a photocatalytic adsorbent where the solids fraction and residence time in the riser is important.
  • The widespread contamination of per- and polyfluoroalkyl substances (PFAS) has provided an impetus to develop engineering solutions for water purification that can be scaled over a wide range of municipal needs. Dr. Paccione has developed a novel treatment system that provides a means for removing PFAS from the water and decomposing them using solar or artificial light. The treatment system is based on a novel multiphase reactor design that can be readily adapted to the required process conditions present at a specific water treatment facility. The New York State Department of Health has filed a patent for the application of the novel reactor design for the treatment of water for PFAS and other potentially toxic substances such as 1,4-dioxane. Dr. Paccione is collaborating with other researchers to add expertise in the fields of photocatalysis and UV reactor design and modeling to bring the needed skills to further develop the water treatment system to address emerging contaminants and wastewater process needs. Future work in this area can be extended to carbon dioxide reduction to C1 precursors such as methanol.
