This is the first AguaClara design to use untapered baffles in the flocculator. The goal is to create a 6 mW/kg energy dissipation rate throughout the flocculator. There are 29 baffles in each of the first two channels to ensure that the water flows through the ports connecting channels, which are at the bottom, correctly. The last channel has 28 baffles because the inlet port is at the bottom and the inlet channel for the sedimentation tank is at the top. The baffles use polycarbonate sheets instead of cement which are easier to remove. This makes draining the system much easier.

Inlet Channel

Wiki MarkupThe inlet channel was modified to have only one opening leading to the sedimentation tank instead of two. See the explanation for this under Sedimentation Tank. The concrete in the inlet channel will be rounded going into the pipe so that the transition of flow is smoother. the construction sequence for this transition will be done as follows:
before pouring the concrete for the base slab of the inlet cchannel, a 90 deg elbow will be coupled to the 6" pipe (substituting the chimeneys). The idea is thet the concrete follows the shape of the elbow in the bottom slab of the channel to reduce the expansion los created by the change in direction of the flow.

Sedimentation Tank

The sedimentation tank design is significantly different from previous designs. The main problem that brought about the change is that too much sludge was settling out in the inlet manifolds at Cuatro Comunidades. There was originally a similar design for Agalteca, so it needed to be fixed. To see a list of ideas on how to fix this problem until the final design was chosen, click here.
