Previous Research by the AguaClara team in Fall of 2005 to Spring of 2006

Laboratory experimentation with the upflow suspended bed lime feeder during the spring of 2006.
The lime feeder research team investigated the possibility of building a lime feeder for the AguaClara plant at Ojojona. In the end flocculation at Ojojona was successful without lime addition and the lime feeder project was dropped. Daniel Smith, Fulbright Scholar, is evaluating the performance of AguaClara water treatment plants in Honduras. He is routinely measuring pH and alkalinity of the raw and treated waters. From Dan's research we know that low alkalinity waters are common in Honduras and that setting an appropriate alum dose is extremely difficult because addition of a little bit too much alum consumes all of the alkalinity and results in low pH water. At low pH the solubility of
