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.
Backwash water, floc hopper waste, and water that is wasted during treatment failures must be managed. Given that water is often in short supply it makes most sense to allow this water to settle and then recycle the slightly clarified water back to the front end of the AguaClara plant. Design a system that uses a minimum number of pumps and that is easy for the plant operators to manage. Size any tanks and pumps and add them to the design for plants in the size range of 10 to 80 L/s.
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.
