Cistern Filter, FCF-6
Benefit: Rainwater is soft, settles rapidly, and requires no
treatment to remove hardness caused by iron or or other minerals.
- HOW DESIRABLE ARE
CISTERNS AS WATER SOURCES?
- In many areas of the United States, rainwater collection can provide large quantities of
relatively clean water. This water has not been affected by sewage treatment or industrial
processes, has not washed through city streets, has not been polluted with the run-off
from septic tanks or barnyards, and has not been contaminated with pesticides or
fertilizer from field run-off. When properly collected, filtered, and stored, this rain
water provides many advantages.
- HOW SHOULD RAIN WATER
Most experts agree that pre-filtration of water before it enters the cistern or storage
tank, combined with a floating intake filter, provides the best possible use of rain water.
Pre-filtration assures many years of use before cisterns require
- WHY USE
A FLOATING FILTER AS THE INTAKE ON A CISTERN?
- For most of the
same reasons you would use a Floating Pond Filter - to remove only the
cleanest water in the cistern (water nearest the surface).
DOES A FLOATING CISTERN FILTER DIFFER FROM A FLOATING POND FILTER?
- The only noticeable
difference is that the cistern filter removes water from closer to
the surface than a pond filter since there is no algae growth in a
cistern. The cistern filter has a shorter stem length.
LONG DO CISTERN FILTER ELEMENTS LAST?
- Depending on
the usage and how efficiently the water was pre-filtered before
storage, the filter elements will last from one to three
years. If you use a filtering roofwasher as a prefilter,
you'll extend the time between filter changes.
