Forgot to add a sand-filter needs backwashing---usually they have a slow 
flow-rate, and a downstream holding tank to accumulate filtered water is 
often a good idea.

Used to own a marina on Lake Livingston, Texas, well-water quality was 
atrocious, had to use a specialized sand filter to take out iron and 
hydrogen sulfide.

Here is a single-tank sand filter with a layer of activated carbon and 
filter cloth, and of course a valve for backwashing.  This has a pretty 
good flow-rate.
