BACTERIAL MITOSIS AND "GROW-THROUGH''
Mitosis is the name for the usual method of bacterial cell division. This division is characterized by resolving the chromatin of the cell nucleus into a threadlike form that condenses into chromosomes, each of which separates longitudinally into two parts, one part or each chromosome being retained in each of the two new daughter cells.
When conditions of growth (cell division) are right (proper environmental conditions temperature, pressure, etc.) and sufficient nutrients, the "threadlike forms" can penetrate the ceramic structure of other ceramic shells and create bacterial cells on the inside of the element.
Super Sterasyl grade filter elements incorporate pure silver into the porous ceramic shell to prevent "grow-through" from occurring.
Super Sterasyl Sub-Micron Ceramic Filter
At the core of the sub-micron ceramic filter is the most basic of elements ... EARTH. This is the same substance which artisans, first in Asia then in Europe, refined into exquisite porcelain and pottery of the Shoguns and Kings. This material is Diatomaceous Earth (D.E.), a fossil substance, made up of very small silicon shells left by trillions of microscopic, one celled algae, called diatoms. Today there are over 1,500 uses for diatomaceous earth, from abrasives for toothpaste, filtering agents for water and milk, heat insulators for kilns, to polishing agents in nail polishes, and much more.
The microscopic pores of a ceramic filter element makes it an extremely efficient filter for the removal of particulate matter and fine sediment from water. Minute particulate matter will quickly plug media style filters, but the ceramics have the added benefit of being cleanable and re-usable. With nominal particulate filtration rating efficiencies of >98% down to 0.2 - 0.3 microns (Spectrum Labs), >99.7% at 0.3 - 0.5 microns, 99.9% at 0.5 - 0.8 microns and 99.99% at 0.9 microns, this is one powerful filter system.
The Super Sterasyl element utilizes the latest technological advances of ceramic filtration by incorporating pure silver impregnation into the porous inner ceramic shell to prevent the growth of bacteria and fungi. Furthermore, the Super Sterasyl ceramic filter element contains activated carbon filling, which removes chemical and organic compounds from the water while also improving taste.
