There are various types of machine using Kieselguhr (diatomacious earth) as a filter medium:- Latest is 'ultrafiltration' used in the most modern juice plants. Second best is the Velo type with horizontal stainless steel plates and automatic dosing, so the earth does not
fall off the plates; unlike the earlier vertical plate type and the earliest 'plate and frame' type which is messy and not good. Kieselguhr must be protected from moisture and odours.
