Application of Multi-Medium Filtration for Water Preparation
Within a wider study of possible applications of some natural materials as filtration media, some physico-chemical properties of anthracite and quartz sand were investigated. The applicability of these materials was tested in the process of separation of suspended particles from kaoline suspensions (model system). They were examined under conditions of the single– and dual–medium open, fast, gravitational filtration. It was found that separation of suspended particles by filtration was almost complete. A significant increase was found in the active filtration period, as compared to classical sand filters.
