How does the Southern Cross Pottery Water Purifier Work?
The Southern Cross Pottery Ceramic Water Purifier is an Australia made, ceramic, gravity fed water purifier that removes virtually all impurities without the need for plumbing or electricity.
How does it work? Water is placed in the top container shaped like an inverted bell, which houses the ceramic water filter with its nozzle protruding through a small hole into the main body of the pottery purifier (please refer to illustration). Water is filtered using a pottery purifier in three ways.
1. The outer micro-porous ceramic wall of the pottery purifier screens the water down to one micron to remove up to 99.99% of bacteria and suspended solids. The tiny pores of the ceramic purifier make it extremely efficient at removing particulate matter and fine sediment such as iron, copper, lead and aluminium to name a few. The ceramic water filter is also a highly effective barrier to bacterial pathogens and water-bourne cysts including e-coli, cryptosporidium, giardia and salmonella.
2. The water passes through the inner core of activated charcoal which removes chlorine, ammonia and bad tastes and odors. Activated carbon works by attracting and holding certain chemicals as water passes through it; it is a highly porous material with an extremely high surface area for contaminant adsorption. (Adsorption is the phenomenon whereby molecules adhere to a surface with which they come in contact with).
3. The ceramic wall of this pottery water filter has been impregnated wtih silver ions to prevent the growth of bacteria in the filter itself and also in the stored water. The silver acts as a natural biocide inhibiting microbiological growth meaning that there is no need to sterilise the pottery filter even when they are used over an extended period of time.
The design of this stoneware water purifier prevents any overflow problems common with two part water purifier systems. Each ceramic water purifier is hand made on the potter's wheel and individually decorated in a variety of colours, many of which are uniquely Australian.
The water purifier is fired to stoneware temperature of 1305 centigrade making it the perfect non toxic material to filter and store drinking water. Firing at this high temperature ensures your water purifier is waterproof and extremely resilient to cracking, crazing and chipping.
Unlike terracotta and earthenware systems, Southern Cross Pottery stoneware water filter system will not grow mould, become stained, deteriorate with age or leave a clay taste in your water. The inside of the clay water purifier is glazed allowing ease of cleaning.
No fumes are given off as with plastics or metals allowing safer, longer storage with Southern Cross Pottery water purifiers. The insulating properties of stoneware water purifiers will help keep your water naturally cool for drinking and ice may be added to the container for chilled water. There is no electricity or plumbing and the stoneware water purifier is small enough that it can be moved easily from room to room.
The PH of the water is increased slightly and this is the result of the calcium content in the media of the cartridge; essentially providing a similar benefit as some alkalizing machines on the market without the added cost.
