Peterson - Drum Pre-Coat Filters System

Our drum pre-coat filters are specifically designed for mounting “pre-coats”, usually of diatomaceous earth, which are then shaved off in very thin layers during a batch run of pre-filter slurry. This results in a clean filtering surface being presented to the pre-filter feed on each revolution of the drum. These units are generally used in clarifying operations where very clean filtrate is the desired product.
