Water Treatment Process Engineer/Consultant for Modular Potable Water System Design

We are seeking an experienced water treatment process engineer or consultant to support the design of a compact modular potable water treatment system for commercial development in Lagos, Nigeria. The treatment philosophy includes:
- Venturi aeration for iron/manganese oxidation
- Catalytic media filtration
- Adsorptive polishing (activated carbon/organic removal)
- UV disinfection
- RO + remineralization for premium applications

The consultant will be responsible for:
1. Reviewing and validating our design philosophy and treatment flow.
2. Assisting with P&ID/process schematic development.
3. Confirming appropriate component sizing (media vessels, pumps, flow rates, UV capacity, RO configuration).
4. Recommending material specifications and modular layout options.

We prefer candidates with experience in:
- Small packaged plants/skid-mounted systems.
- RO-based treatment trains.
- Groundwater iron/manganese removal.
- Venturi aeration or oxidation concepts.

This is a remote advisory role focused on design, not installation.
