PhD in Applied Chemistry | Water Treatment & Disinfection Expert | Chlorination Safety & Infrastructure Protection

Profile Summary

I am a water treatment and drinking water disinfection expert specializing in chlorine-based systems, with a focus on chemical safety, risk mitigation, emergency preparedness, and critical infrastructure protection. I hold a PhD in Applied Chemistry and bring over 20 years of hands-on experience in municipal water treatment, drinking water disinfection, chlorine safety management, and large-scale utility operations. My expertise bridges two closely related domains. The first is drinking water treatment and chlorination systems, where I specialize in the design, optimization, troubleshooting, performance evaluation, and operational improvement of municipal-scale disinfection systems. The second is chemical safety and critical infrastructure resilience for chlorine-based facilities. My work includes hazard identification, risk assessment, risk mitigation planning, emergency preparedness, and the development of implementable safety frameworks for high-risk water and chemical installations. I have served as a senior consultant on national-level water and chemical safety projects, contributing to technical guidelines, emergency response frameworks, infrastructure protection programs, and safety standards for water utilities and chlorine-related facilities. A significant part of my work focuses on developing comprehensive prevention, protection, and emergency response strategies for chlorine systems, addressing both operational hazards and external threat scenarios. This includes the assessment of complex chlorine-related risks and the development of practical mitigation measures to improve safety, resilience, and operational continuity. My experience also includes the development of training frameworks, instructional materials, competency requirements, and technical guidance for personnel involved in chlorine safety, emergency preparedness, and hazardous chemical management programs. In addition to consulting and technical advisory work, I currently lead the operation of a large municipal water treatment plant, with overall responsibility for treatment performance, maintenance, water quality compliance, process safety, and operational reliability. This practical operational experience allows me to develop solutions that are not only technically sound but also realistic and implementable in real-world utility environments. I am also involved in the development of technical standards, guidance documents, and educational content related to water disinfection, chlorination systems, chemical safety, and emergency preparedness. My professional development includes advanced training from Delft University of Technology and specialized chlorine safety programs. Core Services: • Drinking water disinfection system design and optimization • Chlorination system troubleshooting and performance evaluation • Chemical safety and process hazard assessment • Risk assessment and mitigation planning for chlorine systems • Emergency preparedness and response planning • Critical infrastructure protection and resilience assessment • Technical auditing of water treatment and chemical dosing systems • Development of technical guidelines, standards, training frameworks, and instructional materials
