I have a huge well problem. I have muddy water that according to 4 different "water store" experts cannot be filtered. The water will however settle out clear over night.
So I was thinking of setting up a series of 2 400 gallon tanks. Well pump would fill one and settle while separate pump sent other to pressure tank. Then when clear tank was empty it would switch to fill up while settled tank would go to supply.
Anyone know of automatic valves and shutoffs that would work in this scenario?
Any help please. Will post in other forum topics as well.
Thanks |

How often are you going to get the sediment flushed out of the tanks? That's going to be a pain with big 400 gallon tanks..
How old is your well? How deep? Is it possible that your pump is too close to the bottom?
Back flushing sediment filter tanks are available. Do you have any analysis of your water? |

I know colloidal matter is very hard to filter. Muddy water. Uhm! A backwashing filter would be likely to handle it but might need to go into backwash nightly. Is the 'muddy' substances actually soil or could is be something else?
Sometimes a series of pieces of equipment is needed for extreme water conditions.
Is there any sand or gritty matter (settles to the bottom of the glass within a minute or two) in the water? A sand separator may help like below:

Our well is new (actually dug a year ago but just moved in).
400 ft. with pump at about 260.
Water has been tested and its a fine clay mud. We've already tried backwashing filters with no success.
We have a kinetico softner with a .35 micron prefilter and it goes right through. Water doesn't settle fast enough for a chlorinator. It will settle over night though. That's why I thought if we had 2 tanks, one could be used while the other one was settling.

| In a typical sample container, how much settles quickly vs how much is suspended after 24 hr? A better approach is to meter in your tank, a chiton based floc like clarify which will bind material and then can be filtered out using something like filter Ag. I have one customer in Scott's Valley with a spring box next to a seasonal creek and his water after even a mild rain event has turbidity of 300 NTU . After the above treatment, the water is post filtered with a 4"X20" .2 micron filter, we achieved less than.05 NTU. This is after several years of frustration with other dealers and many attempts such as bag filters, spun filters and pleated cartridges. |

What does your well driller have to say about it? Is this a geographical issue, or is this a bad well?
Might also consider a membrane based system such as a backwashable Ultra Filter or Microfilter, Very important that you have good local representation and hopefully some local expereince with the products.
Where are you located? |

UF manufacture's require pre filtration to 100 microns. Residential systems like GE's home spring will foul out in turbid waters. Two ways to approach this; clarification with time or floc, contact and filtration and post treatment. had the well driller flowed this particular well for development? Are you sure this just isn't a breeched well pack? do you have a Pump Tec or similar device? |

UF filters foul on turbid water becuase some dealers and MFG's seem to think you can just hook them up a the house supply and run 5 - 10 GPM. In reality the unit should be sized for work/dirt load. The home spring is great a product for already very low turbidity water but may not be the choice to use "as designed" for water like this.
Run a UF at 10 - 50% of suggested rated flow/flux and at very low pressures and they last much longer and clean much easier.
Also with any floc/chem phys process: They can all be made to work very well with a great product water quality. They can also be a challenge for the average Home Owner to set up and keep running with minimal opperator intervention. |
