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 12: Inception briefing, raw water assessment, treatment options analysis, capex/opex feasibility, basis of design...
