Automatic Whole House Sediment Filter by American Plumber

[corlett]

Item 162424 is an automatic whole house sediment filter by american plumber.

1. What is the approximate micron rating for this system? I don't see it in the manuals.

2. I have a customer that wants one of these for turbidity, but I have heard that turbidity requires fine filtration. Is there a rule of thumb for micron rating filtration for turbidity?

3. How do you drain the backwashed water? Wouldn't it clog up a drain?

1. There is not a published micron rating however you can asssume about 40 micron for a multimedia filter.

2. There is no micron rating for turbidity. You can determine micron requirements fairly accurately using the following settling test:
Use a quart sample of water taken from the water in the toilet tank (stir up the tank before collecting sample). Let the sample stand and settle.
If the water clears in:
seconds the sediment is coarse - 50 micron and up
minutes the sediment is medium - 20 to 50 micron
hours the sediment is fine - 5 to 20 micron
over night or days the sediment is extra fine - 1 to 5 micron
does not settle the sediment is colloidal - submicron

3. Most sediment does not consist of that much volume that it will clog a drain. Discharge to the sanitary drain is generally sufficient for the backwash.

I hope this helps.
Thank you,
