Dewatering Filter for 10" Whole House Filter systems Biodiesel, Black diesel, Waste Vegetable Oil, WVO

This is a water removing filter designed for use in a whole house water filter that uses a 10" filter cartridge.(available on ebay or most home improvement stores) The inner filter is a standard 5 micron filter cartridge and is replaceable. The outer layer is a filter that incorporates a Superabsorbent Polymer that will absorb up to 60 times its volume in water and the impurities carried by water. This filter will not absorb vegetable oils, animal fats or petroleum oils. After the oil exits the inner filter, it is directed through the Superabsorbent Polymer layer which absorbs and holds water but allows the oil to pass right through. The bottom of the Polymer filter extends below the filter cartridge to absorb any water that might settle there. The cloth that contains the Superabsorbent Polymers is a moisture wicking cloth that will collect the water and hold it while the Polymers absorb it. Excessive filtering speed or pressure should be avoided as it will reduce the effectiveness of this and all filters. Oil should still be allowed to settle before filtering to avoid excessive water. See my other lisings for settling filters to aid with this part. The Polymers will swell as they absorb water allowing you to see when the filter should be changed. The outer filter is reusable and only needs to be cleaned and dried (directions are included). It is then attached to a new 10" cartridge and put back into service. The included pictures show how this product works. The first picture is a sample of straight vegetable oil and a sample of black diesel, both with a small Polymer filter in the bottom. It will not absorb the oil. The next picture shows a large amount of water introduced to both samples. (a coin was used to keep the filter from floating to the top of the water level) The third picture shows the swollen filters removed from the now dry samples along with the water.
