304 316 Stainless Steel Precision Filter 0.1μM ~ 100μM For Membrane System Pre Stage Protection

Precision Filter: Used for pre-stage protection of membrane systems, terminal sterilization and particle removal, as well as sterilization and oil removal filtration.

Quick Details

It is a key piece of equipment for terminal precision filtration in water treatment and process fluid systems. Its core design consists of installing one or more replaceable disposable filter cartridges inside a pressure-bearing housing (filter tank). Driven by pressure, the fluid to be treated flows from the outside to the inside of the filter cartridges. Impurities such as suspended particles, colloids, and microorganisms are trapped by the precision filtration medium, thus producing highly purified liquid.

Components and Features

Filter Cartridge:A variety of filtration media and precision options are available (typically ranging from 0.1 μm to 100 μm), including:

Polypropylene (PP) Melt Blown Cartridge: Economical and versatile, featuring depth filtration and a wide precision range.

Polyethersulfone (PES)/Nylon Pleated Cartridge: High flux and high dirt-holding capacity, suitable for applications requiring high flow rates and long service life.

Activated Carbon Composite Cartridge: Combines the functions of adsorbing organic substances and residual chlorine, as well as filtering particles.

Hydrophobic/Hydrophilic Cartridge: Specifically designed for gas filtration or the filtration of special liquids.

Filter Tank (Housing):Made of 304 or 316L stainless steel, the inner surface is polished with high precision, complying with hygienic or industrial standards. The design meets pressure vessel specifications such as ASME or PED to ensure safety.

Sealing System:Adopts a flange quick-opening structure or a clamp-type quick-opening structure, combined with O-ring sealing, enabling rapid filter cartridge replacement and eliminating the risk of bypass leakage.

Optional Accessories:Can be integrated with a pressure gauge to monitor filter cartridge clogging in real time and realize predictive maintenance.

Filtration Precision and Reliability:It can stably provide filtration precision up to 0.1μm, effectively removing fine particles, colloids and bacteria, and ensuring the ultra-high purity of the final product water.

High Flux and Long Service Life Design:The pleated filter cartridges offer a large effective filtration area, achieving high flow rates at low pressure differences, reducing system energy consumption and extending the replacement cycle. the optimized flow channel design minimizes dead zones and improves medium utilization efficiency.

Chemical Compatibility and Material Safety:A wide range of filter cartridge and sealing materials are available, resistant to strong acids, strong alkalis, high temperatures and various organic solvents. compliant with food and pharmaceutical grade contact material regulations such as FDA and EU 1935/2004, ensuring safe and pollution-free fluid handling.

Low Operating Cost and Easy Maintenance:The modular design enables quick and easy filter cartridge replacement without special tools, minimizing downtime to the greatest extent. Standardized filter cartridge interfaces facilitate global procurement and inventory management for customers.

Application Scope

Pre-protection for Membrane Systems (RO/UF/NF):Serving as a critical security filter, it removes fine particles remaining from upstream treatment processes, providing absolute protection for expensive membrane elements against scratches and fouling. It is the cornerstone for the stable operation of reverse osmosis systems.

Ultrapure Water (UPW) Preparation:In fields such as electronics (semiconductors, chips), power (power plants) and laboratories, it is used for terminal filtration after polishing mixed beds or EDI, ensuring effluent meets standards and controlling particles and microorganisms.

Biotechnology and Pharmaceutical Industries:Terminal sterilization and particle removal for process water (WFI water for injection, purified water). Sterilization and oil removal filtration for compressed air and gases.

Chemical and Electroplating Industries:Filtration of high-purity chemicals to ensure product quality. Continuous purification of electroplating bath solutions to remove impurities and improve the quality of plated parts.

Industrial Circulating Water Systems:Used as side-stream filtration or terminal filtration to control microorganisms and particles, and improve system efficiency.
