Prefabrication 1L/s (Prefab)
Overview
The goal of the Prefabrication 1 L/s team is to research, test, and determine fabrication methods for the full-scale plant production in Honduras. We also continue to design novel geometries for low-flow sedimentation tanks and flocculators and refine the integration of the dosing, flocculation, sedimentation, and filtration processes.Spring 2016
This semester, we successfully designed and fabricated a 1/9 scale model of the sedimentation tank. We showed that a large, plastic corrugated pipe was a potential low-weight, low-cost solution to traditional concrete tanks and determined that plastic welding was a viable fabrication method for tank construction in Honduras. We also succeeded in testing our sedimentation tank using a pre-existing tube flocculator in the lab and cleaned 50 NTU water to meet WHO standards.
Fall 2016
The team investigated how to streamline the fabrication methods from summer 2016 and designed/explored alternative methods to fabricate plate settlers and flocculators and lower labor costs.
The original request from Jacobo Nuñez in 2003 that led to the creation of the AguaClara program was for a method to treat water for Honduran villages. Over the past decade, AguaClara has made designs for towns and small cities. We have not yet succeeded in creating a low cost, climate-friendly, high performing treatment plant for villages that rely on turbid surface waters. The team created a working prototype design and after preliminary testing in the AguaClara laboratory, we turned it over to Agua Para el Pueblo to test it in a pilot project in Honduras. The main challenge was to select fabrication materials and develop fabrication methods. The prefabricated AguaClara plant treated approximately 1 L/s and will provide water for approximately 300 people.
Introduction and Objectives
Spring 2017
This semester, the team will be building upon work that was done in previous semesters to continue to improve the performance of the 1 L/s pilot plant implemented in Honduras during January 2017. The team will be focusing specifically on the development of the flocculator. The team will be designing and fabricating a tapered flocculator. The performance of the plant with the tapered flocculation system and without it will be compared to get a better grasp of which parameters are significant to future flocculator design.
