Chemical process engineer

Key Responsibilities Groundwater treatment design Characterise raw water from boreholes, surface sources, or blended sources; specify the analytical scope required for design. Select and size unit operations: pretreatment (screening, sedimentation, coagulation/flocculation), filtration (multimedia, granular activated carbon, membrane), disinfection (chlorine, UV, ozone), softening, demineralisation (RO, ion exchange), and advanced oxidation as required. Produce mass and energy balances, hydraulic profiles, equipment specifications, and operating philosophy for the plant. Verify compliance with SANS 241 (potable), DWS general and special limits, and any fit‑for‑purpose standards specific to the client's use case. Process documentation across all six ECSA stages Stage 1–2: Inception briefing, raw water assessment, treatment options analysis, capex/opex feasibility, basis of design. Stage 3–4: Developed design, P&IDs and PFDs, equipment data sheets, specifications, Bo Qs, tender documenta...
