What is the maximum flow rate per sq. ft. for both pressure and vacuum type DE filters in public pools without slurry?

1 gpm
2 gpm
3 gpm
4 gpm

The correct answer is: 1 gpm

DE filters are commonly used in public pools to filter out impurities and debris. The maximum flow rate per sq. ft. is an important factor to consider as it determines the efficiency of the filter. In this case, the maximum flow rate for both pressure and vacuum type DE filters should not exceed 1 gpm to ensure proper functioning and prevent clogging. Option B 2 gpm is incorrect because it exceeds the recommended maximum flow rate and can potentially lead to clogging and reduced efficiency of the filter. Option C: 3 gpm is incorrect for the same reasons as option B. Option D: 4 gpm is incorrect as it is above the recommended maximum flow rate and can cause strain on the filter, leading to potential malfunctions. Overall, it is important to adhere to the recommended maximum flow rate per sq. ft. in order to maintain the effectiveness of DE filters in public pools.
