Product Specifications

Technical details and manufacturing context for Industrial Grade Ceramic Membrane Filter Element

Definition

A precision-engineered ceramic membrane element designed for separation processes in chemical manufacturing. This component serves as the core filtration unit in membrane separation systems, enabling particle removal, clarification, and concentration of chemical products. It integrates into larger filtration assemblies within chemical processing plants, providing reliable separation performance under harsh chemical environments. Manufacturers supply these elements to OEMs building complete filtration systems for various chemical production applications. The element is constructed from advanced ceramic materials such as alumina, zirconia, or silicon carbide, offering high thermal and chemical resistance. Its porous structure allows for size-exclusion-based separation, with pore sizes ranging from 0.05 to 1.4 micrometers, making it suitable for microfiltration and ultrafiltration duties. The membrane area varies from 0.1 to 10 square meters, accommodating different flow requirements. Operating pressure is typically 1.0 to 1.6 bar, and the element can withstand temperatures up to 800°C. It operates across the full pH range (0–14), ensuring compatibility with aggressive chemical streams. Physical dimensions include lengths from 250 to 1500 mm and outer diameters from 30 to 60 mm, with weights ranging from 0.5 to 5 kg. Porosity is 30–50%, and burst pressure is at least 6 MPa, providing a safety margin under pressure spikes. Flux rates vary from 50 to 500 L/(m²·h) depending on feed characteristics and pressure. Material grades include α-Al₂O₃, TiO₂, and ZrO₂. These elements are designed for integration into membrane housings and require proper sealing and support. Selection should consider pore size, membrane area, and compatibility with process conditions. Verification of model-specific values and standards with the legal manufacturer or supplier is essential before procurement.

Working Principle

The ceramic membrane filter element operates on the principle of size exclusion. The porous ceramic structure contains microscopic channels that allow fluid to pass through while retaining particles and molecules larger than the pore size. The separation is purely physical, driven by pressure differential across the membrane. As the feed stream flows across the membrane surface, smaller components permeate through the pores, while larger substances are retained on the feed side. The controlled porosity, typically 30–50%, ensures a balance between permeability and mechanical strength. The pore size, ranging from 0.05 to 1.4 μm, determines the retention characteristics. The element is designed to operate under a pressure differential of 1.0–1.6 bar, with a maximum temperature of 800°C. The ceramic material provides chemical resistance across the full pH range, making it suitable for aggressive chemical environments. The separation efficiency depends on the feed characteristics, operating pressure, and membrane area. Regular backwashing or cleaning may be required to maintain flux rates, which typically range from 50 to 500 L/(m²·h). The element's integrity is ensured by a burst pressure of at least 6 MPa, providing a safety margin under pressure spikes.

Frequently Asked Questions

What is the typical pore size range for this ceramic membrane filter element?

The pore size ranges from 0.05 to 1.4 micrometers, as listed in the product parameters. This range allows for microfiltration and ultrafiltration applications, retaining particles and molecules larger than the specified pore size. The exact pore size should be selected based on the required separation efficiency and confirmed with the manufacturer for the specific model.

Can this element withstand high temperatures and aggressive chemicals?

Yes, the ceramic materials used (alumina, zirconia, silicon carbide) provide high thermal resistance up to 800°C and chemical resistance across the full pH range (0–14). However, the actual compatibility depends on the specific material grade and process conditions. Always verify the material grade and operating limits with the supplier for your application.

What is the operating pressure and burst pressure?

The recommended operating pressure is 1.0 to 1.6 bar. The burst pressure is at least 6 MPa, providing a safety margin under pressure spikes. These values are reference ranges; the actual limits may vary by model and should be confirmed with the manufacturer.

How do I select the right membrane area and length for my process?

The membrane area ranges from 0.1 to 10 m², and the element length from 250 to 1500 mm. Selection depends on the required flow rate (flux rate 50–500 L/(m²·h)), feed characteristics, and available housing dimensions. It is essential to consult the manufacturer or supplier to determine the appropriate configuration for your specific separation duty.
