AAL High-Efficiency Separation Filter Cartridge-Liquid and Liquid

Product Overview

AALfilter’s separation filter cartridge is a high-performance filtration element made of Teflon (PTFE) hydrophobic material, specifically designed for oil-water separation. Its core principle leverages the oleophilic and hydrophobic properties of the material—when oil passes through, water is trapped on the filter surface, forming droplets, while the oil flows freely, achieving purified oil output. These cartridges are widely used in industries such as power generation, petrochemicals, and textiles to effectively remove water and contaminants from fluids, enhancing equipment efficiency and lifespan.

Key Features

✅ Superior Separation Performance

Multi-layer composite filter media structure with micron-level precision (0.3–10μm), removing 99.99% of solid particles and free water.

Teflon material ensures a dynamic contact angle >90° , delivering >95% water-blocking efficiency.

✅ Extended Service Life & Durability

Stainless steel core and epoxy-coated end caps withstand pressures up to 0.7MPa and temperatures from -30°C to 180°C.

50% higher dirt-holding capacity reduces replacement frequency and maintenance costs.

✅ Smart Adaptability

Modular design supports custom sizing (OD: 100–152mm, length: 290–1450mm), compatible with various fine filters.

Optional PLC control and flow meters for automated operation.

❓Frequently Asked Questions (FAQ)

1. What types of liquids can this separation filter cartridge handle?
It is designed to separate immiscible liquids such as water from oil, oil from solvents, or other liquid-liquid mixtures where conventional filters are ineffective.

2. How does the cartridge achieve liquid-liquid separation?
It uses a coalescing principle: small dispersed droplets are captured and merged into larger droplets, which then separate naturally due to gravity and density differences.

3. What is the filtration efficiency?
Typical removal efficiency exceeds 99% for dispersed liquid droplets down to 5–10 microns, depending on operating conditions and fluid properties.

4. Can the filter be used in high-pressure systems?
Yes. The cartridge can be customized for high-pressure applications depending on the housing and material specifications.

5. Is this filter reusable or disposable?
The separation cartridge is generally disposable, but long service life minimizes replacement frequency.

6. Can AAL Filter customize the filter for my specific process or chemical compatibility?
Yes, we offer full customization including media selection, flow rate, dimensions, and chemical-resistant materials based on your application needs.

7. How often does the filter need to be replaced?
Replacement frequency depends on contamination levels, flow rate, and operating conditions. Regular differential pressure monitoring is recommended.

Your Trusted Partner for High-Efficiency Separation Filter Cartridge – Liquid and Liquid

AAL Filter offers a high-performance separation cartridge designed specifically for removing immiscible liquids from fluid mixtures, such as water from oil-based fluids or solvents. This is achieved through a coalescing and separation mechanism integrated into the filter structure.

As the liquid mixture flows through the multi-layered filter media, the dispersed fine droplets of the secondary liquid phase (such as water) are captured and coalesced into larger droplets. The filter media is engineered with a gradient fiber structure to maximize surface contact and coalescence efficiency. Once coalesced, the heavier liquid phase naturally separates from the primary fluid by gravity and is collected or drained from the system.

AAL separation filter cartridge ensures improved fluid purity, system protection, and reduced processing downtime.
