Non Technical Summary
Particulate Matter (PM) emission from animal facilities carries toxic gases, odor, and pathogens, thereby raising significant concerns on health, food safety, and environmental quality. Increased public concerns and existing PM regulations make it imperative to develop both effective and economically feasible technologies to mitigate PM emissions from animal production facilities. To date, success in this area has been limited. The goal of this project is to develop two innovative electrostatic PM control systems that demonstrate promises of high PM collection efficiency, low air resistance, capacities in disinfection of airborne pathogens, and relatively low cost. The specific objectives and approaches are to (1) characterize key PM parameters and airflow conditions in typical poultry houses that affect electrostatic PM mitigation, (2) develop, test, and model optimized modules and full-scale prototypes of Electrostatic Precipitators (ESPs) and Electrostatic Scrubbers (ESSs) under lab conditions, and (3) assess and evaluate their performances and economic feasibilities for PM control at poultry facilities. The major project outcomes are expected to enable the poultry industry to effectively mitigate PM emissions, which will contribute to improved health, reduced outbreaks of foodborne diseases, enhanced environmental quality, and sustainable animal production. Our experienced multi-state and multi-disciplinary team is uniquely positioned to ensure the success of this project.

Outputs
Target Audience: Animal producers, Professionals working with the animal industries, Researchers, and Graduate students. Changes/Problems:The project was originally scheduled to begin in January 2016, but actively began in June 2016 after a graduate research associate was recruited. In addition, we originally planned to use a wind-tunnel test chamber to be built by the USDA ARS Application Technology Research Group. Due to USDA hiring budget freeze and government shutdown, the making process of the wind tunnel chamber was significantly delayed. A simplified wind-tunnel test chamber had to be designed and built at the PI's lab for the laboratory tests. Due to these delays, the project schedule and timeline have been adjusted accordingly with an approved one-year extension. The Covid-19 pandemic further delayed the field evaluations of the ESP and ESS prototypes, with field evaluations ultimately were concluded in Jan. 2021. An addition one-year extension of the project enabled more data analysis and preliminarily tests of the ESP and ESS effects on pathogen control.

Impacts
What was accomplished under these goals? The specific accomplishments are summarized per the Objectives as the followings: Objective 1. To ensure effective design and operation of the electrostatic PM control devices, data on critical PM characteristics and airflow conditions were collected and analyzed for PM and airflow characteristics affecting ESP and ESS operation at typical manure-blet layer houses in Midwest States. The PM characterizations knowledge have been used for development of ESP and ESS devices and published as a journal article to share the knowledge with producers and researchers. Objective 2. A comprehensive simulation model of the poultry PM collection process in an ESP module was developed using COMSOL software. The COMSOL ESP model was validated and then used for simulation and optimization of the ESP designs for maximum PM removal efficiency and minimum energy use. This optimized ESP module achieved a PM2.5 removal efficiency of 80.5%, 91.3%, and 99.6% for hot, warm, and cold weather, respectively, and a PM10 removal efficiency of 100% for all seasons. The respective relative prediction errors of 10.1%, 3.0%, and 1.0%. This COMSOL ESP model can be used as an inexpensive alternative to developing physical prototypes when evaluating ESP designs for PM mitigation in poultry facilities. Two ESP module prototypes have been successfully developed and constructed according to the preliminarily optimized designs of ESP models. A wind tunnel/test chamber has been designed and constructed for laboratory tests and physical simulation of the preliminarily optimized ESP module prototypes. Laboratory tests were conducted to first validate the COMSOL ESP model, and then further optimize the operating conditions of the ESP module prototypes. The optimum operating parameters for a smaller ESP model for indoor PM removal at manure-belt layer houses included an applied voltage of 26 kV and an air velocity of 1.50 m s-1. These operating conditions resulted in mean PM2.5, PM10, and TSP removal efficiencies of 90.3% ± 3.3%, 93.1% ± 2.7%, and 94.5% ± 2.1%, respectively. A larger ESP for application at exhaust fans performed best at an applied voltage of 40 kV and a mean air velocity of 1.50 m s-1. Mean PM2.5, PM10, and TSP removal efficiencies achieved at these operating conditions were 98.2% ± 0.5%, 98.9% ± 0.3%, and 99.0% ± 0.3%, respectively. Both ESPs performed well enough to proceed with future field evaluations in a commercial poultry facility. A laboratory study on effects of electrode materials and dimensions on droplet charging efficiency was conducted. In this study, ring-shaped electrodes were selected to test effects of three electrode materials (copper, stainless steel, and graphite) with various dimensions on droplet charging efficiency. A Faraday pail charge measurement device was used to measure the droplet charge generated by the electrodes. A reduced factorial design with four factors including electrode material, electrode diameter, nozzle height, and applied voltage was used in this study to investigate the charging efficiency affected by the factors. A 304L stainless steel electrode was found to achieve higher droplet charge-to-mass ratio (CMR) values than identically shaped electrodes made from either copper or graphite. The optimal stainless steel electrode inner diameter was 100 mm. The 304L stainless-steel electrode with this optimal diameter and a height of 45 mm achieved the highest mean CMR of 0.435 ± 0.002 mC kg-1 at an applied voltage of -11 kV with the bottom of the nozzle tip positioned 15 mm below the top of the electrode. Three types of spray nozzles were tested with a range of applied voltages, mass flow rates, and water conductivities to determine the optimal spray configuration to maximize the CMR of the spray droplets for an ESS to more effectively collect airborne PM in poultry facilities. A 80° tapered edge flat spray nozzles achieved the largest mean charge mass ration of (CMR) 0.613 mC kg-1. A linear regression model for CMR was developed and used for optimization of applied voltage and water mass flow rate to maximize the achievable CMR. The optimal ESS configuration to maximize the CMR of spray droplets at a water conductivity of 0.05 S m-1 was an 80° tapered edge flat spray nozzle, an applied voltage of -11.6 kV, and a mass flow rate of 0.397 kg min-1, resulting in an optimal CMR of 0.578 mC kg-1, equivalent to 20.3% of the Rayleigh charging limit. Based on the optimized spray charging designs, an electrostatic spray scrubber (ESS) has been developed and optimized in a laboratory setting for mitigation of poultry PM emission. The full-scale ESS was tested in a wind tunnel simulating dusty air flow in poultry facilities. A weighted electrostatic spraying statistic (WESS) was developed to quantify the overall ESS performance in terms of PM2.5 and PM10 removal efficiencies and water consumption. A linear regression model for WESS was developed and optimized. Testing the ESS at conditions close to the identified optimal values resulted in a WESS value of 89.8 ± 1.5 and respective mean PM2.5, PM10, and total PM removal efficiencies of 94.5% ± 1.0%, 79.9% ± 3.1%, and 75.2% ± 4.4%. This model will be a useful tool for future research to develop applications of this technology under various environmental conditions. Objective 3. Two full-scale electrostatic precipitators (ESPs) were tested at a commercial poultry production facility to assess their PM removal capabilities. The smaller ESP prototype was installed inside the poultry production facility and the larger ESP was installed in a custom-built sampling chamber attached to the exterior wall of the poultry house to isolate the airstream of a 1.32 m diameter exhaust fan from ambient air. The smaller ESP had mean PM2.5, PM10, and TSP removal efficiencies of 79.6% ±5.7%, 92.7% ±4.4%, and 94.6% ±2.0%, respectively, while the large ESP demonstrated the efficiencies of 93.6% ±5.0%, 94.0% ±5.0%, and 94.7% ±4.4% for PM2.5, PM10, and TSP removal, respectively. The smaller ESP featured an initial cost of $7,095 and an estimated annual operating cost of $120. For the larger ESP, the initial cost per unit was $8,610, with an estimated annual operating cost of $123 per unit. Installation of these multi-ESP systems was not cost-effective. A full-scale electrostatic spray scrubber (ESS) was installed at a commercial poultry house just before an exhaust fan to mitigate particulate matter (PM) emission. Overall, the ESS achieved a mean PM2.5, PM10, and TSP (total suspended particles) removal efficiencies of 90.5% ±10.0%, 91.9% ±8.2%, and 92.9% ±6.9%, respectively. The full-scale ESS costed $3100 and used 201.96 m3 of water and 950.4 kWh of electricity annually. The estimated total annual operating cost, including water, electricity, and maintenance, was $319 per ESS unit. The full-scale ESS has been found to effectively mitigate PM emissions at a commercial poultry facility in a cost-effective manner compared to previously tested ESPs. A preliminary test of the ESP and ESS device's capability in deactivating general bacteria and selected pathogens were tested. The field test results showed that an average removal efficiency of airborne pathogens in summer conditions was 59.7% for the ESP. The mean removal efficiencies of an ESS were 38.8±9.5%, 39.7±25.7%, and 64.8±30.0% for the total airborne bacteria, Campylobacter spp., and E. coli., respectively. These devices need to be further optimized for deactivation of pathogens to protect public and environmental health.

Progress 01/01/20 to 12/31/20

Outputs
Target Audience:• Animal producers, • Professionals working with the animal industries, • Researchers, and • Graduate students. Changes/Problems:The field tests of the ESP and ESS units were delayed due to the Covid-19 pandemic, weather conditions (warm weather conditions in Nov. and Dec. of 2020 and extreme winter storm in January and early February of 2021), and student illness (from late Dec. 2020 to January of 2021). We were not able to conduct the field evaluations of the ESP and ESS prototypes with typical winter weather conditions. We hope to finish the winter tests as soon as we can prior to March 2021. Furthermore, due to the fact that most other university labs were not be able to operate normally in spring and summer of 2020, our plan to preliminarily test effect the developed dust control devices on bacteria and pathogen concentrations were postponed. We hope to perform some of these tests in 2021 when we can send air samples to other collaborating labs. What opportunities for training and professional development has the project provided? Project team members gave presentations at the 2020 ASABE Annual International Meeting online. How have the results been disseminated to communities of interest?The project results have been disseminated through Zoom meetings among the team members. In addition, we have disseminated the scholarly results of the project through professional conference papers and/or presentations. What do you plan to do during the next reporting period to accomplish the goals?The field tests of the ESP and ESS unites were delayed due to challenges in setting up field, pandemic, and weather conditions. The team will continue to finish the field test of large ESP and ESS in 2021. Specifically, we will Conduct field tests of the large full-scale ESP and ESS devices in a commercial layer farm in winter conditions. Perform techno-economic analyses for both the optimized ESP and optimized ESS devices based on the complete field test data. Conduct primary tests on effects of the ESP and ESS devices on bacteria and pathogen concentrations of exhaust airflow.

Impacts

Target Audience: Animal producers, Professionals working with the animal industries, Researchers, and Graduate students. Changes/Problems:The project was originally scheduled to begin in January 2016, but actively began in June 2016 after a graduate research associate was recruited. In addition, we originally planned to use a wind-tunnel test chamber to be built by the USDA ARS Application Technology Research Group. Due to USDA hiring budge freeze and government shutdown, the making process of the wind tunnel chamber was significantly delayed. A simplified wind-tunnel test chamber has to be designed and built at the PI's lab for the laboratory tests. Due to these delays, the project schedule and timeline have been adjusted accordingly and one-year extension has been approved. The field tests of the ESP and ESS unites were delayed due to challenges in setting up field test and equipment failures. The Covid-19 pandemic further delayed the field tests. We are making efforts to resume the field test as soon as we can and hope to finish the tests in 2020. What opportunities for training and professional development has the project provided? Members of the project team have given presentations at the 2019 ASABE Annual International Meeting in Boston, Project members will give presentations at the 2020 ASABE Annual International Meeting online. How have the results been disseminated to communities of interest?The project results have been disseminated through in-person meetings among the team members.
