At least I hope so . Last year I installed a drip irrigation system
that is supplied by my well in my garden . It worked swell for a while ,
then I started having problems with plugged emitters . It turns out I'm picking up some very fine silt/sand/? with the water .
This year I'm adding a system to get that silt out of the water
before it reaches the emitters . Filtration ain't going to work unless I install a swimming pool type system . My solution is based on the dust collector systems in common use at cabinet shops . The basic principle
is to get the medium - air or in this case water - swirling so that the heavier components are forced to the outside by centrifugal force to
settle at the bottom . I'm using a 55 gallon plastic drum as my
"cyclone" (originally held almond butter) , the inlet will be near the
top and angled to impart swirling . The outlet will be near the bottom ,
a horizontal pipe to the center , then an elbow and vertical pipe about
a foot long . I haven't decided yet if the barrel will be pressurized ,
I'm thinking probably not . Last year I used open standpipes about 2
feet tall , using the overflow to gauge and adjust the flow rate .

Filters are available at less than $3. Change only takes me a few minutes. Reading reviews on the swirl filter makes it look like a crap shoot as it could clog in a few days at worst. Let us know how you make out.

Yes, the center at the bottom, where you periodically flush them out.
Anything heavier than water will tend to move to the outside and down as
they spin.

The water is coming from our well . When the pump isn't running the
water in the barrel will be static , any silt will naturally settle to
the bottom . When it is running the water will be swirling and the silt
will be moving to the outside and down . With the outlet pipe in the
middle of the barrel I expect to see a marked reduction of plugged
emitters . I'm thinking the barrel will need to be kept full to not have those disturbances in the flow patterns ... or if I let the level drop between watering I'll need to let the pump run long enough to establish
the rotation and fill the barrel before I start to draw water . More new ground for me .

This is not a filter ... this is simple physics . There is a swirling/rotation imparted to the incoming water by angling the inlet
pipe . The silt/sand particles , being heavier/denser than water , are
forced to the outside by centrifugal force . By drawing the outlet water
from the center of the barrel I hope to avoid picking up so much junk
that it plugs my emitters . If this doesn't work to my satisfaction my
backup plan is to fill the barrel , let it sit for a while to settle ,
then use the water , refill and repeat .
