My use is filtering grinders running tungsten carbide.
Over years we have had paper dragouts, centrifugal that look like a washing machine drum, hydrocyclones, 2000 gallon settling tanks, and DME systems.
All of them not so good for one reason or other.
After all that experimenting we now just have a 30-40 gallon tank at each machine with one or two baffles and use these after the pump and one the way into the machine:
APEC Water Systems - Whole House Water Filters - Water Filtration Systems - The Home Depot
Originally we put in a 30-40 micron followed by a one micron. That was a mistake as we began filter some of the coolant itself out of the water.
Now we leave the front empty and put a 30-40 in the second tube, they quickly turn into a 5-10 as they build a layer.
A single tube unit works just as well, you want the 4 inch by 20 inch size and use pleated filters.
The original plastic wrenches that come with these for changing the cartridges are too short and break, we use a chain wrench.
Our cycles are short from 6 to 120 seconds so we wanted to keep pressure on all the time for instant startup but not have a pump always running so we went to these for our coolant pumps:
1 HP Stainless Steel Shallow Well Pump and Tank with Pressure Control Switch - 950 GPH
That has worked out very well. Note that these pumps do not come with a foot valve so you need to one with on the intake.
