The current design of the AguaClara entrance tank was created after difficulties with grit clogging the flocculator at Agalteca and Marcala. The solution to the grit problem was to make a large entrance tank that is effectively a horizontal flow sedimentation tank, which would settle out larger "grit" particles. The entrance tank could be made smaller by making a more effective grit removal system that uses plate settlers that double as flocculator baffles. This section of entrance tank could be integrated into the first channel of the flocculator. By reducing the size of the entrance tank or integrating it into the flocculator, the plan view size of the overall plant will decrease. This means a decrease in plant construction costsIn response to the problems observed in Honduras involving grit clogging the flocculator, the GRIT team has gone through several iterations of grit removal design using plate settlers before flocculation. The team invented and explored options for each design, and improved upon them to optimize their feasibility before comparing them. In the end, the team has decided that the iteration called the Channel GRU is the best of the three designs that were explored. It drastically decreases the plant’s plan view area by reducing the entrance tank to nothing but a trash rack, elegantly ensures flow distribution through creative plate-to-floor geometry, and effectively incorporates chemical dosing and rapid mix after the grit removal plate settlers. This design is currently being considered for construction in a 4 L/s plant in Honduras.
