How to Remove Sand from Well Water at 55 GPM

Hello,

We are a small community water system. Three wells to filters, chlorine injection before storage tanks. TCEQ defines our shallow wells as ground water under the influence of surface water. Wells are approx 45 ft deep. Two of the wells actually meet filter requirements before filtering. The third well (after about 3 years of dry weather) has excessive sand. It will flow about 55 gpm. We are seeking your opinion of a filter method for the sandy well before intersecting the common supply line (the three wells flow into a common flow line before the filter system and chlorination). These wells only run on demand, when the tanks are low. We normally only run on two wells. Presently we are not using the sandy well, but would like to be able run with one of the other wells should one well go down. What do you suggest?

Dear Nolan,

For this application, we recommend the Lakos sand separator with purge kit. The separator will remove any particles that will settle out in a jar or beaker within 3 minutes. For a flow of 55 gpm, we recommend the 1.5" model.

How to Remove Iron & Odor from Well Water for Home Irrigation System

Hello,

Private well to be used for lawn irrigation system. Flow rate max is 10GPM and expect to use approx. 1600 gals per day (maybe as high as 1800 gals) during extended dry summer periods. Iron content approx. 7PPM and a faint rotten egg smell of standing water.

Thanks,
Rich

Hello Rich,

Air Charger Iron Filter 2510XST

For your application we recommend two 1.5 cubic foot size model Air Charger Iron Filters in parallel because of the high demand. However, these only work if your existing well system has a pressure tank. If your well has no pressure tank, you would not be able to use a back-washing iron filter.

In order to handle the demand, it would be best to have 3.0 cubic of iron filter media.  However, the largest iron filter you can get that is non-chemical, and can backwash with 7 GPM is the AIO 2.0 CF or 2.5 CF size, both of  which use 7 GPM for backwash. This will give you the capacity you need to treat the water per day.  In your application twin tanks are preferable to one larger tank, since a single large iron filter tank would require more than 10 GPM to backwash it.
