- Undertake feasibility and options assessments, process sizing and mass balances; compare treatment performance, operability, energy, chemicals, residuals and whole-life cost.
- Develop treatment designs within your expertise, including physical and chemical treatment, biological wastewater treatment, disinfection, sludge handling or advanced treatment.
- Prepare process flow diagrams, process design calculations,



equipment duties and process inputs to piping and instrumentation diagrams. Maintain consistency across documents.
- Develop functional descriptions, operating philosophies and control requirements with electrical and automation engineers; coordinate hydraulic and mechanical interfaces.
- Prepare equipment specifications and technical evaluations of vendor proposals, recording assumptions, performance requirements and departures from the design basis.
- Participate in safety in design, HAZOP and operability reviews; assess chemical handling, process upsets, treatment reliability and continuity of service during upgrades.
- Support construction queries, commissioning plans, performance testing and troubleshooting within the agreed scope. Record findings and recommend evidence-based improvements.

including design deliverables.
- Demonstrated design capability in at least one relevant treatment area and the ability to explain process selection, sizing assumptions and performance limitations.
- Sound understanding of water chemistry or biological treatment, as relevant to your experience, together with mass balances and interpretation of operating data.
- Ability to develop process documentation and work with mechanical, civil, electrical and automation engineers on integrated designs.
- Solid spreadsheet, analysis and technical report writing skills; ability to apply relevant Australian water quality guidance, project approvals and client requirements.

Desirable experience -

- Desalination or reuse experience, including reverse osmosis, membrane filtration or membrane bioreactors; relevant tools such as WAVE, IMSDesign, BioWin or GPS-X.
- Australian utility, industrial or mine water projects; treatment optimisation, pilot trials, brine management, sludge treatment or resource recovery.
- Commissioning and performance testing experience; HAZOP participation; CPEng or RPEQ, or active progress towards professional registration.
