Issues
When work began on the pilot plant in the Fall 2008, several leaks were discovered. The plant had to remain shut off until the leaks would be repaired. At first it has seemed that the leaks were in the pipes, so all of the joints in the pipes were caulked. After the caulk had dried, water continued to leak from the system. It was discovered that the leveling tank (a plastic bucket) was leaking.
Solutions and Changes to the Pilot Plant
When caulk did not seal the leveling tank, the outlets to the sed tanks were sealed off (to allow the flocculator team to conduct experiments) and the leveling tank was replaced with a PVC pipe. This is the current set-up as of mid-October 2008.
