filters are generally of the sand filter type or
diatomaceous earth type. Sand filters have high backwash
requirements with a considerable amount of water, heat, and
chemical being dumped to drain. Diatomaceous earth filters
have high pressure drops, requiring more pumping power. In
both cases, pool pumps need to be sized for worst case
conditions of the filters being plugged. Perlite media
filters are pretty much self-cleaning with low backwash
requirements and low pressure drop, allowing the use of a
VFD to vary flow rate between occupied and unoccupied
periods.<o:p></o:p></span></p>

<p>Dear Aaron, <o:p></o:p></p>
<p>For the schedule, it really depends on the project you are
working at I think.<br>
The gym I frequent uses fans in addition to the cooling,
that can be a energy efficiency strategy.<br>
Good luck,<br>
