Vacuum Filter Press: Advanced Dewatering Technology for Fine Slurries and High-Purity Filtration

Jingjin Filter Expands Industrial Filtration Capabilities with Vacuum Technology for Critical Slurry Separation

In the field of precision filtration, effectiveness of speed and dryness are not the most important factors, but purity and particle control. The vacuum filter press which not only processes fine particle slurries but also achieves low residual moisture has so far been a core technology in sections like pharmaceuticals, chemicals, and metallurgy as well as in rare earth processing.

Jingjin Filter, one of the market leaders in the global filtration system design field, is now offering customers new choices of powerful vacuum filter press, specializing in progressive solid-liquid separation. The technical expertise in the industrial filter press sector that Jingjin Filter has accumulated over the years enables the company to provide vacuum systems made of sustainable materials and sophisticated filter press cloth which are the main components used to achieve the highest standards of modern businesses.

What Is a Vacuum Filter Press?

Unlike traditional hydraulic or mechanical filter presses, a vacuum filter press utilizes negative pressure to draw liquid through the filter medium. This vacuum-assisted dewatering process significantly enhances:

• Filtration speed for fine particle suspensions
• Product purity by minimizing turbulence
• Filtrate clarity in applications requiring low solid carry-over
• Moisture reduction, especially for hard-to-dewater slurries

Jingjin’s vacuum filter systems are equipped with sealed chambers, reinforced filter cloths, and corrosion-resistant materials, making them ideal for continuous or batch-based high-purity applications.

Key Advantages Over Standard Industrial Filter Presses

While a conventional industrial filter press relies on mechanical pressure and gravity flow, vacuum filtration introduces several unique benefits:

• Higher efficiency with finer particle capture
• Gentler processing, ideal for sensitive products (e.g., APIs, enzymes)
• Reduced energy consumption compared to high-pressure mechanical dewatering
• Improved automation with real-time vacuum control and monitoring

This makes the vacuum filter press a superior solution for industries that cannot compromise on separation quality, such as food-grade production or rare metal recovery.

Filter Press Cloth: The Unsung Hero

No filtration system performs without the right filter media. Jingjin, as a top-tier filter press cloth supplier, designs its vacuum systems around custom-engineered cloths to optimize:

• Permeability and retention rate
• Chemical and thermal resistance
• Durability under vacuum conditions
• Ease of cake release and cleaning

Options include woven monofilament cloths, needle-punched nonwovens, and hybrid materials for specialty use cases. All are precisely matched to plate dimensions and vacuum system requirements.

Applications Across High-Precision Industries

Jingjin’s vacuum filter press systems are the choice of a good number of industries covering solid-liquid separation very carefully. The following industries are being served by Jingjin’s vacuum filter press systems:

• Pharmaceuticals: Crystallized compound separation, active ingredient refinement
• Chemicals: Fine powder recovery, acid/base slurry treatment
• Mining & metallurgy: Rare earth elements, lithium brines, copper concentrates
• Food & beverage: Clarification of juices, starch recovery, brewery waste
• Environmental: Hazardous sludge dewatering, wastewater polishing

Through each and every application, Jingjin offers one-stop-shop solutions—right from pilot testing until the full-scale production line implementation.
