Overview
This research project focused on identifying and selecting an optimal filter fiber material for wastewater filtration plants located in Hamilton, ON. The work combined materials database analysis, Ashby methodology, and environmental impact assessment to recommend a material that met both technical and sustainability criteria.
Context
Wastewater filtration requires filter media that can effectively capture contaminants while withstanding harsh chemical and biological conditions. Material selection for such applications must balance filtration performance, durability, cost, and environmental impact. Hamilton's local filtration infrastructure provided a concrete use case for the analysis.
Methodology
A variety of materials were analyzed using Ansys Granta, a comprehensive materials database and selection tool. Material indices relevant to filtration applications (e.g., strength-to-weight, chemical resistance, porosity) were identified. Ashby Charts were created using hand-calculated material index lines to systematically compare and narrow down candidate materials.
The Ashby approach allowed for multi-objective comparison by plotting materials on axes representing key performance criteria. Materials falling within the desired regions of the charts were shortlisted for further evaluation.
Sustainability Assessment
Environmental impacts were evaluated using Eco Audit assessments and graphs. The analysis emphasized sustainable materials, considering factors such as embodied energy, carbon footprint, recyclability, and end-of-life considerations. This dimension was critical for a municipal infrastructure application where long-term environmental impact matters.
Key Outcomes
- Systematic material selection using established engineering methodology
- Integration of technical performance with sustainability criteria
- Application of Ansys Granta and Ashby methodology to real-world infrastructure
- Recommendation of an optimal filter fiber material for Hamilton wastewater plants
