Ceramic Water Filters

Ceramic materials are made from the Earth. More specifically from the remains of silicon shells left by algae that settled to the bottom of the Earth's waters years ago. These deposits were discovered when the Earth's bodies of water dried up. The discovery of this “Diaomaceous Earth” had sparked new ideas for technological uses, especially in water filtration. The ceramic filter is very beneficial because it filters out a variety of contaminants that may be present in the water while the essential minerals remain. About 99.88% of contaminants known to cause water-born diseases are filtered out by ceramic water filters.
Depth filtration is the unique way that contaminants are filtered from ceramic unit. With this advanced level of filtration comes a quality is extremely cleanly and virtually contaminant-free. Doulton filters contain within their ceramic shells about 80,000,000 pores in which to trap bacteria and other harmful contaminants that could be present in household drinking water. Pure silver incorporated throughout the ceramic filter prevents bacteria from growing. Silver plays an important role in the maintaining of cleanliness within the filter. When silver comes into contact with water, the silver gives off ions. The bacteria cells takes in the ions and it then become neutral.
Some of the ceramic filters that we have available are actually reusable. To clean these filters for reuse, simply brush off the outer layer of contaminants under running water with a small brush. Some filters may be reused up to 60 times before its filtration capabilities have been exhausted. When the filter has been used down to a diameter of 1.75", that is a good indication that it should be replaced. These ceramic filters should not be cleaned with any type of chemical agents in order to ensure the cleanliest of filtration.
We carry three different brands of ceramic filters: Pentek, Franke and Doulton. The Pentek ceramic filter is the CRE-1, which has a 1 micron rating and is reusable. The FRX-02 is the Franke brand of ceramic filter that we carry, which has a 0.2 micron rating but is not reusable. Some of the Doulton Ceramic filter that are reusable are listed here: DS-1000, Imperial OBE, Sterasyl OBE.

KDF Process Media

KDF process media, original known as Kinetic Degradation Fluxion, are high-purity, granulated copper and zinc-based alloys that treat water through a process based upon the principle of redox (oxidation reduction). KDF’s unique combination of copper and zinc creates an electro-chemical reaction. During this reaction, electrons are transferred between molecules, and new elements are created. Some harmful contaminants are changed into harmless components. Free chlorine, for instance, is changed into benign, water-soluble chloride, which is then carried harmlessly through the water supply. Similarly, some heavy metals such as copper, lead, mercury and others, react to plate out onto the medium’s surface, thus being effectively removed from the water supply.

There are many benefits to using KDF media. KDF media are 100% recyclable and contain no chemical additives. KDF will enhance performance, reduce maintenance, and extend the life of your current filtration system. They will also help control microorganisms by creating an environment that’s deadly to microorganisms and that interferes with the ability of many other microorganisms to function. KDF media will also help extend the life of granular activated carbon, a media that is often used in conjunction.

KDF media can be broken down into two (2) principle products: KDF 55 and KDF 85. KDF 55 granules are most effective in removing 99.9% of chlorine and water soluble heavy materials from point-of-use (POE) treatment systems of municipal water supplies. KDF 85 granules effectively reduce iron and hydrogen sulfide and can be used alone or to protect existing water filtration/purification technologies in POE treatment of groundwater supplies. There is also KDF-F (Fines), which can be incorporated into carbon blocks for chlorine removal, bacterial control, and similar applications.
