Introduction to Filter Presses
Filter presses are used to separate liquids and solids by forcing the liquid fraction of a feed slurry through a permeable filter cloth. The separation occurs in chambers formed between recessed plates clamped together in a steel frame. The process involves pumping slurry under high pressure, filling chambers with solids, and pushing liquid out through the filter cloth. Additional steps include removing residual slurry, air purging, and cake washing to achieve high solids in low permeability cakes.

AFP IV™ Automatic Filter Press
The AFP IV™ Automated Filter is designed for efficient solid-liquid separation, offering high throughput and continuous operation in harsh environments. It features automatic cake discharge, easy maintenance, and low operating costs. Key features include push closure cylinders, automatic cloth washing, and a variety of plate designs and filter media.

Operational Features
- Cloth Shaker: Assists in cake discharge by vibrating filter cloths.
- Programmable Logic Control: Allows for various levels of automation.
- Cylinder Crosshead: Reduces cycle times by quickly opening and closing plate stacks.
- Flood Wash: Cleans plates and media between cycles to prevent media blinding.
- Quick Media Change-Out: Allows for fast exchange of filter cloths.
- All Hydraulic Operation: Powers various operations from a single hydraulic unit.
- Drip Trays: Prevent rewetting of discharged cake.
