Floating Cistern Filters

Floating 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 RAIN WATER 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 BE FILTERED?
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 cleaning.

 

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).

 

HOW 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.

 

HOW 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.
