Membrane vs. Chamber Filter Press: Which to Choose?

When it comes to solid-liquid separation, the choice between a Chamber Filter Press and a Membrane Filter Press can significantly impact your operational efficiency, costs, and compliance performance.

Each has clear advantages — the key is knowing which one fits your process, your priorities, and your industry best.

This guide highlights the strengths of each technology, provides a side-by-side comparison, and helps you identify which is better suited for your operation.

Why Choose a Chamber Filter Press？

The Chamber Filter Press is a tried-and-true technology known for:

Lower upfront investment
Simple mechanical design
Easy maintenance and operation
Reliable performance in low-to-medium volume applications

Best for:

• Plants with limited budgets

• Processes with low solids concentration

• Industries where cake dryness isn’t critical

• Entry-level or first-time users of filter press systems

Why Choose a Membrane Filter Press?

The Membrane Filter Press adds a second filtration step using inflatable membrane plates that apply additional pressure to the filter cake.

Lower final cake moisture (as low as 35–45%)
Faster cycle times
Reduced sludge disposal and drying costs
Better suited for automation and continuous operation
Improved cake uniformity and cleaner cake release

Best for:

• Industries with high sludge disposal costs

• Applications where dryness affects compliance or cost

• Large-scale, automated operations

• Businesses pursuing energy efficiency and sustainability goals

Side-by-Side Comparison

Industry Fit: Who Should Use Which?

Chamber Filter Press Ideal For:

• Small and medium-sized plants

• Ceramics, textiles, light industrial wastewater

• Operations with limited staff or low automation

• Buyers focused on CapEx savings

Membrane Filter Press Ideal For:

• Municipal and industrial wastewater

• Mining and metallurgical operations

• Chemical, pharma, and food industries

• Companies aiming to reduce TCO and environmental impact

Quick Tip: If you’re paying high sludge transport or drying costs, membrane presses usually pay for themselves faster.
