System Components

Pressure vessel housing vertical filter leaves, slurry feed pump, filtrate collection system, compressed air or gas for cake discharge, control panel managing cycles, piping and valves coordinating flows, and solids discharge mechanism. Integrated package ready for installation.

Pressure Filtration

Operating at 50-200 psig drives liquid through filter cake faster than gravity. Pressure differential overcomes cake resistance maintaining flow rate. Higher pressure enables thinner cakes or finer filtration. Enclosed system handles volatile or hazardous materials safely.

Leaf Configuration

Vertical filter leaves with cloth or mesh media provide large surface area. Typical vessels contain 10-100 leaves depending on capacity. Leaf spacing accommodates cake thickness typically 10-50mm. Vertical orientation allows gravity-assisted solids discharge after filtering.

Automated Operation

Control system manages filtration cycle automatically. Filling phase admits slurry. Filtering phase continues until pressure drop limit or timer. Cleaning phase discharges cake using air blow or wash. Drain phase prepares for next cycle. Fully automated operation requires minimal supervision.

Cake Discharge Methods

Gas blow dislodges dry cake from leaves. Vibration or bumping assists release. Wash spray removes sticky solids. Rotating leaves pass discharge zone continuously. Method selection depends on cake properties and product recovery requirements.

Applications

Chemical catalyst recovery with product wash, wastewater treatment solids removal, mining tailings dewatering, pharmaceutical API isolation, food processing clarification, and any batch or continuous process requiring pressure filtration.

Material Selection

Stainless steel 304/316 for food, pharmaceutical, and chemical service. Carbon steel for mild applications. Alloy construction for corrosive streams. Filter media materials compatible with process chemistry and temperature.

Filtrate Quality

Achieves clarity from 1-50 microns depending on media selection. Precoat materials enable fine filtration below 1 micron. Multiple stages possible for ultra-clean filtrate. Quality monitoring ensures specification compliance.

System Integration

Interfaces with upstream process providing slurry feed. Filtrate routes to downstream processing. Solids discharge to collection or disposal. Control system coordinates with facility automation. Skid-mounted package simplifies installation.

Performance Benefits
