From this data, it can be inferred that in the first day that the 100g100 g/L solution was allowed to sit, a lot of the precipitate did settle out. Most of the precipitate found in the diluted 30g/L solution probably came from the precipitate that remained suspended on the top of 100g/L solution due to the CO2 gas risingHowever, reducing the supernatent of the 100 g/L concentration to 30 g/L after the first day and allowing it to settle again did result in the additional formation of precipitate. This additional precipitate was a result of an additional day of settling, due to the fact that this test was done in less than the 3 suggested days. This was done because of a time constraint. It is also possible that some of what was measured in the initial 100 g/L concentration as precipitate was actually calcium hypochlorite that didn't dissolve due to the saturation of solution. Thus adding additional water to the supernatant of that solution would result in more calcium hypochlorite dissolving and more precipitate forming.
Conclusions
With increasing concentration of Calcium Hypochlorite Solution, the threat of clogging becomes greater due to increased amount of precipitate forming. There are several ways however to reduce this threat.
