A Chamberland filter, also known as a Pasteur-Chamberland filter, is a porcelain water filter invented by Charles Chamberland in 1884.^[1] It is similar to the Berkefeld filter in principle.

[edit] Design

Schematic diagram of a Chamberland filter

It consists of an unglazed porcelain tube that contains a ring of enameled porcelain through which the inflow pipe fits. The core of the porcelain is made up of a metal pipe with holes through which water flows out and is collected. Inflow is pressurized so filtration occurs under force.

[edit] Types

There are 13 types in general: L₁ to L₁₃.
L₁ filters have the coarsest pore size while L₁₃ have the finest.

[edit] Usefulness

It is as useful as other ceramic and porcelain filters. It is a good bacterial water filter used mainly as a high volume water filter^[2][3]. The filter works more quickly when the water supplied is under pressure. As other filters of its kind, it cannot filter viruses like Hepatitis A and mycoplasma. It is used in removal of organisms from a fluid culture in order to obtain the bacterial toxins.
