Division: | Engineering & Computing Sciences | Category: | Junior | Region: | Fraser Valley | City: | Abbotsford, BC | School: | Barrowtown Elementary | Abstract: | This is an experiment to determine if Water Hyacinths can reduce the salts in liquid livestock manure and greenhouse wastewater. Salt levels were measured for a one-month growing period using an electrical conductivity meter. We saw significant results up to 40% reduction in salts benefiting both farmers and the environment. |
