For the first three days, the height of precipitate in the bottom of each cylinder increased. At day four, the amount of precipitate did not increase from day three.
In the future, the 50 gallon drums that hold the Calcium Hypochlorite solution should should have exit flow valves installed at a height high enuff enough from the bottom, so that any percipitant precipitant formed and settled does not flow out of the tank at this valve.
Measuring the height from the bottom of a container that occurs , to the top of the settled precipitant that forms, will help us determine
Using the height to place the exit valve.
The fact that after 3 days , no more precipitate settles out, gives a good estimate of time to wait before using sending the calcium hypochlorite solution into the plant. Waiting 3 days to use the solution and pouring out only the liquid at the top of solution the precipitant and bellow the film formed at the top of the container should decrease the amount of precipitate in the system and help to eliminate clogging. Further we would recommend some type of filtration of the solution to remove the flocs of precipitant that are levitating in the middle of the holding container.
