A Pressure Leaf Filter is an advanced liquid filtration system designed to handle industrial processes requiring high-efficiency solid-liquid separation. These systems are equipped with 10 to 60 filter leafs, stacked within either a vertical or horizontal pressure-resistant vessel. Each leaf is a drainage unit covered by a wire mesh or textile cloth, ensuring effective filtration while handling hazardous or high-pressure processes.
How Pressure Leaf Filters Work
The filtration cycle starts with sealing the vessel and pre-coating the filter leafs with a filtration aid, like diatomaceous earth or perlite, to enhance performance. This pre-coat is circulated within the vessel for around 10 minutes to ensure the leafs are properly coated. The system then operates under pressure, forcing the slurry through the filter medium. The solids are retained on the surface of the precoat layer, while the clarified liquid passes through the filter leaf and into a collection system.
