Process Control Engineer

Position objective and summary

• To provide process and operational technical support for waste acceptance and treatment decisions by translating laboratory data into process feasibility, system impact, and cost evaluation.

Main tasks / activities / responsibilities

1. New Waste Technical Assessment

. Work closely with laboratory Chemists to conduct process-level evaluation of newly received wastewater, liquid waste, or mixed waste streams

. Assess suitable treatment routes and required pre-treatment based on laboratory results (e.g. pH, COD, oil & grease, toxicity, inhibitory substances)

. Evaluate the potential impact of new waste on existing treatment systems, including physico-chemical, biological, and membrane systems

2. Process Analysis & Treatment Strategy Development

. Analyze the feasibility of different treatment options from a process engineering perspective

. Compare alternative process configurations in terms of:

o Treatment performance

o Operational stability

o Chemical and energy consumption

o System risks (e.g. biological shock, scaling, membrane fouling)

. Provide technical recommendations to Operations and Commercial teams to support waste routing and treatment strategy decisions

3. Cost & Operating Parameter Analysis

. Estimate treatment costs based on laboratory results and process conditions, including:

o Chemical consumption

o Power consumption

o Sludge generation

o Membrane usage and replacement

. Analyze the impact of key operating parameters on treatment performance and cost

. Support the development and maintenance of treatment cost models and technical reference databases

4. Process Control & Technical Support

. Provide process-level technical support to plant operations teams

. Participate in abnormal operation analysis (e.g. effluent quality fluctuation, biological inhibition, system overloading)

. Propose process adjustments and mitigation measures to reduce operational risks

5. Documentation & Communication

. Review and consolidate laboratory reports, providing process-based conclusions and recommendations

. Prepare technical evaluation summaries for internal decision-making and external technical communication when required

. Participate in cross-functional discussions involving Laboratory, Operations, and Commercial teams

6. Safety & Compliance

. Ensure that all process recommendations and technical decisions comply with EHS requirements

. Participate in risk assessments for new waste streams and new processes (RA / MOC)
