Advanced Vertical Pressure Leaf Filter for Continuous Liquid Clarification

The Vertical Pressure Leaf Filter is a high-efficiency industrial filtration system designed for continuous or batch clarification of liquids containing fine solids. It uses vertical filter leaves installed inside a pressure vessel to achieve deep filtration with high clarity output and minimal product loss.

This equipment is widely used in chemical processing, edible oil refining, petrochemical industries, and wastewater treatment where high-capacity, low-maintenance filtration is required.

What Is a Vertical Pressure Leaf Filter?

A vertical pressure leaf filter consists of a sealed vertical pressure tank equipped with multiple vertical filter elements (leaves). These leaves are covered with fine filter mesh or cloth.

During operation:

• Slurry enters the pressure vessel

• Pressure forces liquid through the filter leaves

• Solids are retained on the leaf surfaces

• Clean filtrate is collected and discharged

When filtration is complete, the system is cleaned by vibration, air blowback, or cake discharge.

Applications of Vertical Pressure Leaf Filter

The vertical pressure leaf filter is widely used in heavy-duty industrial processes:

Edible Oil Industry

• Fuel and oil purification

• Process liquid clarification

Food & Beverage Industry

• Syrup filtration

• Sugar solution clarification

• Beverage processing

Environmental Applications

• Industrial wastewater treatment

• Slurry separation

• Recycling systems

Advantages of Vertical Pressure Leaf Filter

1. High Filtration Efficiency

Large filtration area ensures high throughput and fine particle removal.

2. Closed System Operation

Prevents contamination, leakage, and exposure to hazardous materials.

3. Low Product Loss

Maximizes recovery of valuable liquids and reduces waste.

4. Easy Maintenance

Filter leaves can be cleaned quickly using air or vibration systems.

5. Strong Industrial Adaptability

Suitable for high-temperature, high-pressure, and corrosive environments.

Vertical vs Horizontal Pressure Leaf Filter

• Vertical type: Compact footprint, easier cake discharge, suitable for space-limited plants

• Horizontal type: Larger filtration area, suitable for very high-capacity processing
