Abstract:
1. A water reaction tank for reacting water with a flocculant, the water containing suspended solids, the water reaction tank comprising: a) a housing having an input, an output, and a water flow path disposed between the input and the output, the flow path passing through a mixing section and a reaction section; the mixing and the reaction sections being disposed in the housing and each section further comprising sidewalls; the mixing section being disposed vertically above the reaction section; the mixing section further comprising the input and a first flow port, the first flow port configured for providing communication for the water flow path between the mixing section and the reaction section; the reaction section further comprising the outlet; b) a top plate disposed on top of the mixing section, the top plate comprising flocculant ports for inserting the flocculant into the mixing section; c) each of the mixing section and the reaction section containing baffles, the mixing section baffles comprising a plurality of first baffles disposed substantially in a spaced-apart configuration in a central portion of the mixing section and further comprising a plurality of second baffles disposed substantially in a spaced-apart configuration along at least one of the sidewalls of the mixing section extending inwardly towards the central portion of the mixing section, the mixing section baffles configured to encourage turbulent flow to increase contact with the flocculant, the reaction section baffles encouraging turbulent flow and increasing the length of the water flow path.
