Home Roughing Filters
RF/x home roughing filter.
- Removes sand and silt (settleable solids)
- Removes 50% to 80% turbidity (cloudiness)
- Pre-treatment for slow sand filters
Roughing filters are used primarily as pretreatment for filter systems that may not be able to tolerate high turbidity or suspended solids in the source water.
The RF/x is an upflow course media filters that produces up to 2 gallons per minute, or 2,880 gallons per day, and is appropriate for use with either an SSF/x or SSF 1.25 home slow sand filters. The upflow feature allows for maximum removal efficiency coupled with simple maintenence. By opening the downwash valves, flow through the filter is reversed at a high rate, cleaning the filter by flushing filtered particles out. This system allows for years of use of the filter without gravel replacement.
