BERKEFELD FILTER Meaning and Definition

1. A Berkefeld filter is a type of gravity-fed or pressure-driven water filtration system that is specifically designed to remove impurities from water, making it safe for drinking. This filter is named after its inventor, the German bacteriologist Wilhelm Berkefeld, who developed it in the late 19th century.

   The Berkefeld filter consists of a cylindrical ceramic shell, typically made of porous diatomaceous earth, which serves as the filtration media. Contaminated water is poured into the upper reservoir of the filter, and gravity or pressure assists in driving the water through the microscopic pores of the ceramic material. As the water flows through, the pores trap and remove impurities, such as bacteria, protozoa, suspended solids, and some viruses.

   The efficiency of a Berkefeld filter is enhanced by the use of a pre-filter, typically made of cloth, which retains larger particles and prevents clogging of the ceramic filter. Additionally, an activated carbon filter may be incorporated to further improve water quality by eliminating taste, odor, and certain chemical contaminants.

   Berkefeld filters are often utilized in emergency situations, outdoor expeditions, and remote areas where access to safe drinking water is limited. They provide a reliable and efficient means of purifying water without the need for electricity or complex equipment.

2. A filter of diatomaceous earth through which bacteria of ordinary size cannot pass, so that the filtrate is practically sterile.

Etymology of BERKEFELD FILTER

The word "Berkefeld" in "Berkefeld filter" is derived from the name of the German bacteriologist Karl Wilhelm Max von Berkefeld. He was a scientist who worked for the Berkefeld Filter Company, which was based in Germany and specialized in manufacturing porcelain filters.

The Berkefeld filter, also known as the Berkey filter, was invented by Karl Berkefeld in the late 19th century. It was an early type of water filter that used a porous ceramic material made from clay or diatomaceous earth to separate impurities from water. It became popular for water purification purposes, particularly during explorations and expeditions where access to clean water was essential.

Over time, the name "Berkefeld filter" became associated with this type of ceramic water filter, highlighting Karl Berkefeld's contribution to its development and popularity.
