Ceramic Filtration Technolog, Ceramic Water Filter

New water purification technologies have been introduced during the last decades. Ceramic water purification technology has proven to be very effective when it’s necessary to remove tiniest particles from the water.

Another name for ceramic water purification system is “dead-end purification” or “depth purification”.
Several processes lie in the basis of the dead-end purification.

The first technology sieves the particles of 0.5 µm and larger. This water purification technology is called “direct interception”. Particles run into a small pore and are trapped by synthetic dead-end membranes.
The second technology is called “bridging”. Particles less in size than 0.5 µm can not be captured by the membrane but when they interact with each other they form a combination of two (or more) particles that can not pass through the pore. They block the entrance to the pore and stop the particles of even smaller sizes. Thus a finer filtration is produced. In necessary the layers of the particles may be removed by the brush or scouring pad.

One more water purification technology based on ceramics is the “inertial impaction”. The liquid flows alongside the tube and faces a surface barrier. The water flows around the barrier while particles are captured in front of it.

Water purification technologies called “depth purification” remove much smaller particles than water filter that use porous membrane.
Ceramics is a complicated structure. Water that comes into ceramics depth water filter has to pass through labyrinths of tubes, lines and passages. The path of the water has a lot of turning and curves hundred of times. During the entire path particles are separated. And those particles that haven’t been removed at the entrance to the ceramic structure are removed at the following stages. The passages water flows through are hundreds of times smaller than pores of ordinary water purification membranes.
Then small particles often struck into each other and form clusters big enough to be captured in dead end cavities.
One more thing that makes ceramics depth water purification technology effective is Van der Waals forces. They attract tiny particle to the ceramics surface and the particles are absorbed by the ceramics.

But ceramic water filter does not capture bacteria that given good condition can multiple. To kill the bacteria a small amount of silver is embedded into the ceramics water filter. The silver stops the growth of bacteria.
