WWTP Process Engineer

Highlight • 5.5 Working Days • Medical Benefits • Shuttle bus provided Position Objective and Summary • The WWTP Process Engineer is responsible for the operation, monitoring, optimization, and continuous improvement of industrial and hazardous wastewater treatment processes at the wastewater treatment plant (WWTP). • This role provides technical judgment, process troubleshooting, and engineering support to ensure stable compliance with discharge standards, operational efficiency, and EHS requirements. Main tasks /Activities / Responsibilities 1. Process Operation and Optimization • Responsible for daily operation, monitoring, and optimization of industrial and hazardous wastewater treatment systems. • Cover key treatment units, including but not limited to: • Physico-chemical treatment: Lamella clarifier, DAF, CAF • Advanced oxidation processes (AOP): Micro-electrolysis oxidation, Fenton oxidation, electro-catalytic oxidation, catalytic ozonation, UV photocatalytic oxidation • Biological treatment: Anaerobic systems (e.g. UASB, CSTR), aerobic systems (activated sludge, MBR) • Tertiary / polishing treatment: MBR, RO • Adjust operating parameters based on influent water quality variations (COD, BOD, SS, oil & grease, toxicity, etc.). 2. Technical Evaluation and Process Development • Conduct technical evaluation of new incoming wastewater or waste streams and determine suitable treatment routes and pretreatment requirements. • Plan, organize, and execute bench-scale tests (e.g. jar tests, pilot trials) to verify treatment feasibility. • Provide technical recommendations to support operational decisions and commercial assessments. 3. Troubleshooting and Problem Solving • Handle system abnormalities such as effluent non-compliance, biological inhibition, membrane fouling, and process instability. • Perform root cause analysis (RCA) and propose corrective and preventive actions (CAPA). 4. Documentation and Technical Management • Prepare, update, and maintain SOPs, process operating parameters, and technical reports. • Guide technicians and laboratory staff on sampling, testing, and on-site process adjustments. • Participate in government inspections, customer audits, and technical discussions. 5. Safety and Compliance • Ensure safe operation of chemical systems, advanced oxidation units, and biological treatment processes in compliance with EHS requirements. • Participate in risk assessments (RA) and management of change (MOC) reviews. Job requirements (education, linguistic ability, professional experience, leadership qualities, soft skills etc.) 1. Education • Bachelor’s degree or above. • Major in Environmental Engineering, Chemical Engineering, Applied Chemistry, Biotechnology, or related disciplines. 2. Professional Experience • Minimum 5 years of experience in industrial wastewater or hazardous wastewater treatment. • Hands-on operational experience in one or more of the following systems is preferred: • Advanced oxidation processes (Fenton, electrochemical, ozone, UV) • Biological treatment systems (anaerobic + aerobic, MBR) 3. Professional Competency • Ability to independently perform process evaluation, troubleshooting, and operating parameter optimization. • Strong understanding of common wastewater quality parameters and their impact on treatment systems. • Competent in bench-scale test design and data analysis. 4. Soft Skills and General Competency • Good communication skills with operations, laboratory teams, and management. • Strong sense of responsibility and ability to make sound technical judgments under abnormal conditions. • Able to work in a plant-based, on-site operational environment.
