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.
