Sand filter

We have a 36,000 gallon in ground pool. We have had a cartridge filter for 15 years and are looking at installing a Pentair Triton II TR140 sand filter. Two years ago we installed a Pentair pump, not sure what size, but it is a variable speed. We live in the middle of California, in the Valley. We live in a heavy farming area. We are surrounded by vineyard and Almond trees. Needless to say, a lot of dust. Will the filtering system we are looking at installing be able to handle all the fine particles of constant dust? I would be very upset to have spent all that money on a new system to only end up with a cloudy pool.
