Optimization of Domestic Greywater Treatment Processes for Direct Reuse – Collaboration with SPAREau

Optimization of Domestic Greywater Treatment Processes for Direct Reuse – Collaboration with SPAREau

Delivery institution and unit

IEM / ProMem

Internship description

Main Responsibilities:

Greywater Characterization:
Analyze the physicochemical and microbiological composition of domestic greywater (organic matter, surfactants, microplastics, pathogens).
Identify target pollutants for safe reuse (irrigation, toilet flushing, cleaning).

Laboratory/Pilot Testing:
Evaluate the effectiveness of combined treatment processes (membrane filtration, adsorption, UV/electrochemical disinfection) for direct reuse.
Participate in pilot-scale tests (e.g., microfiltration) and propose optimizations.

Performance Analysis:
Monitor key parameters (COD, BOD, turbidity, pathogen removal) and compare with regulatory standards (e.g., French REUT regulations).
Assess the technical and economic feasibility of scaling up the process.

Collaboration with SPAREau:
Contribute to adapting SPAREau’s solutions for residential or collective applications.
Draft technical reports and suggest improvements for existing systems.

Results Dissemination:
Assist in writing a technical deliverable and presenting results during meetings with the company and IEM.
Potential co-authorship of a publication or conference poster
