Doulton Ceramic Water Filter Elements

Doulton ceramic replacement candles and cartridgesIn addition, a variety of dedicated fittings are placed inside the bore of the element to remove chlorine, bad taste and odor, pesticides, herbicides, industrial solvents and heavy metals.

This ceramic candle combination provides: 100% rejection of cysts and >99.99% of pathogenic bacteria: Depth filtration of particulates >0.2 micron (dirt, asbestos, iron etc).

With it's exclusive all 100% natural multi stage purification technology, Doulton turns even heavily polluted waters into safe and wholesome drinking water without the use of harsh or distasteful chemicals.

Doulton ceramic filter elements utilize the natural properties of high purity specialized diatomaceous earths to provide a range of strictly controlled pore sizes giving maximum filtration efficiency together with high porosity for maximum flow. Doulton ceramic filter elements can be quickly and easily cleaned many times to prolong their working life.

The filter elements are produced using the latest ceramic techniques to provide a hollow porous ceramic which is fired at a temperature in excess of 1000 C. They are designed to operate with water flow going from the outside to the inside of the element. A variety of dedicated fillings can be placed inside the bore of the element to combat specific water contamination problems. For more details see Doulton water filtration technology

All the regular elements are produced in two inch (49 mm) nominal diameter. Standard lengths are five inch (13 cm), seven inch (I 8 cm), and ten inch (25 cm). Other lengths are available to meet special customer requirements. For mounting purposes all candle elements are traditionally supplied with a food grade plastic mount which terminates in a 1/4 inch BSP male thread. There are two standard length mounts; the long mount is 1-5/8 inch (41 mm) long used for gravity filters, the short mount is 3/4 inch (19 mm) long used for pressure and some gravity water filters. Alternative mounts/thread lengths can be custom built.
