IMPROVED BIOSAND METHODOLOGIES FOR SUSTAINABLE CLEAN WATER SOLUTIONS IN NORTHERN HONDURAS
Impact/Purpose:
The project has two primary objectives. The first objective is to improve manufacturing techniques for biosand filter construction, focused on reducing the cost and time required to build each filter. The second objective is to investigate the relationship between organic carbon content of source waters and the performance of the biosand filters. This information can then be used to develop recommendations for filter operation, such as hydraulic loading rates, for various source waters.
Description:
Both aspects of the project will lead to improved construction and operation of biosand filters in Honduras. The Hondurans who have taken on the challenge of constructing and distributing biosand filters appreciate the support and expertise that can be provided in improving the construction process as well as the profitability for them. They also benefit from the experience we can provide when troubleshooting problems in both construction and filter operation and maintenance. Because the influent water quality can vary widely depending upon the source used, additional information on how filter operation can be modified in response to these variations will be extremely valuable.
