By Dan Vorhis Summary: At a cost of greater pressure drop and requisite abrasion, sintered diatomite or diatomaceous earth (DE) ceramic filters—in a field test—delivered longer life, lower “use-cost” and better filtration efficiency than other microfilters. Ceramic’s greater capacity and lower use-cost result from large “effective” surface area, as the actual surface area of the cartridge is multiplied by the number of cleaning cycles afforded. In field tests of portable water filter designs, sintered diatomite, or “ceramic” filters proved to be very efficient and cost effective compared to other filters. Ceramic cartridges are available in industry standard configurations, and are…
