Ideas
High flow rates require large diameter pipes that are both expensive and difficult to install. An alternative would be to use a flat plate LFOM and use a masonry connection between the entrance tank and the flocculator. The goal is to create an alternative design for the entrance tank that uses a flat plate LFOM.
AguaClara Implementation Partner organizations are requesting designs for many communities. The task of this team would be to work with those organizations and use the AguaClara Infrastructure Design Engine (AIDE) or the previously created designs. Implementation Partners are requesting the following designs:
| Partner | Country | Project site | Estimated Flow Rate |
|---|---|---|---|
| Bahir Dar University | Ethiopia | University Campus | Pending |
| Hidrosan | Colombia | various | Pending |
| Water For People and Agua Para La Vida | Nicaragua | pending | pending |
| Agua Para el Pueblo | Honduras | various | 6 to 430 L/s |
Off-campus project teams could create the designs for a specific water treatment project that is of interest to them. The design process could involve developing a strategy to introduce new technologies to their context, regulatory requirements, and permitting processes. Given that AIDE is still under development it is most likely that the designs from the first generation design tool will be used. One of the significant design review requirements is to take the dimensions from the preliminary design and verify that the design meets the design specifications.
Backwash water, floc hopper waste, and water that is wasted during treatment failures must be managed. Review "Integrated Design and Operation of Water Treatment Facilities by Susumu Kawamura for options. Work with Agua Para el Pueblo and the pilot plant at CUWFP to determine what fraction of the raw water is wasted. Evaluate the available options and propose a low cost option for on site management of the residuals. Develop the code to design the residual management system.
Find EPA regulations regarding reuse of backwash water. Could backwash water be treated by floc/sed and then returned to the head end of the treatment plant?
Design a CDC for flows above 100 L/s.
- Determine when a larger float valve is required for the constant head tank and locate an appropriate option.
- Design a method to generate laminar flow in a single large diameter transparent pipe by inserting smaller round, square, or hexagonal tubes inside the pipe. Propose a method to design and fabricate this system and select materials that are chlorine resistant.
- Design the plumbing for the coagulant from the constant level tank to the place where the coagulant is injected below the LFOM.
Design an AguaClara plant on a skid (containerized for transport by tractor trailer) for deployment in the US
- 10’ x 40’ container plant
- Design a compact AguaClara plant in a container. Consider fold out walkways and a tent style roof. This would be for the US market and for rapid deployment.
