Summary
Patrick Sullivan is a dedicated Water Treatment Engineer with 6 years of experience in designing, optimizing, and managing complex water and wastewater treatment systems for municipal and industrial clients. Proven expertise in process engineering, regulatory compliance, and project execution, consistently delivering cost-effective and sustainable solutions. Adept at leveraging advanced analytical techniques and hydraulic modeling to enhance operational efficiency and meet stringent environmental standards.
Experience
- Led the design and commissioning of a 15 MGD municipal drinking water treatment plant upgrade, reducing operational costs by 12% through optimized chemical dosing and filtration processes.
- Managed cross-functional teams of 5-7 engineers on three concurrent water infrastructure projects, ensuring on-time and within-budget delivery for projects valued up to $25M.
- Developed comprehensive hydraulic models using WaterCAD and SewerCAD for complex pipeline networks, improving system reliability by 20% and identifying critical infrastructure vulnerabilities.
- Conducted treatability studies and pilot plant evaluations for industrial wastewater streams, achieving 95% compliance with new EPA discharge limits for a major petrochemical client.
- Assisted in the design and optimization of biological wastewater treatment plants (WWTPs), contributing to a 10% improvement in effluent quality for two municipal clients.
- Performed data analysis on water quality parameters and operational performance, identifying trends and recommending process adjustments that saved $50K annually in chemical consumption.
- Prepared detailed engineering reports, permit applications, and technical specifications for water and wastewater infrastructure projects, ensuring adherence to state and federal regulations.
Projects
- Conducted a comprehensive feasibility study for a direct potable reuse (DPR) system, evaluating various treatment trains including RO, UV-AOP, and granular activated carbon.
- Provided cost-benefit analysis and risk assessment, guiding the client's $100M infrastructure investment decision for future water supply.
- Collaborated with regulatory agencies to ensure proposed designs met stringent water quality and public health standards.
- Designed an integrated wastewater treatment and resource recovery system for a manufacturing plant, reducing freshwater intake by 30% and achieving zero liquid discharge targets.
- Implemented a new anaerobic digestion process that generated 1.5 MW of renewable energy from industrial effluent, offsetting significant operational costs.
- Successfully navigated complex permitting processes with state environmental agencies, securing all necessary approvals ahead of schedule.
- Developed a comprehensive stormwater management plan for a rapidly developing urban area, incorporating green infrastructure and low-impact development (LID) strategies.
- Modeled stormwater runoff and pollutant loading reductions, demonstrating a projected 25% decrease in flood frequency and 40% improvement in receiving water quality.
- Facilitated public workshops and stakeholder engagement to build consensus and support for proposed infrastructure improvements.
Education
- Thesis on Advanced Oxidation Processes for micropollutant removal in drinking water.
- Dean's List recipient, 2019 and 2020.
- Graduated Magna Cum Laude with a GPA of 3.8/4.0.
- Member of the American Society of Civil Engineers (ASCE) student chapter.
