Filter Cartridge

I. Overview of Reverse Osmosis Systems

High levels of impurities are present in natural water, making a pretreatment system prior to reverse osmosis indispensable. A comprehensive pretreatment system not only ensures the long-term stable operation of subsequent equipment but also operates safely over a long period. The choice of pretreatment depends on the water quality and includes multi-media filters, activated carbon filters, filters, softeners, iron and manganese removal filters, and disc filters, among others.

1. Multi-Media Filter

Process Features: Multi-media filters, also known as mechanical filters, primarily intercept physical impurities in water, removing suspended matter, solid particles, and some colloidal substances.

Materials include: fiberglass, carbon steel (with internal anti-corrosion), and stainless steel SUS304 (lined with rubber for corrosion resistance), catering to various industry production and process requirements.

Control Methods: Manual operation, semi-automatic, fully automatic (including automatic control valves, pneumatic valve groups, and electric valve groups, etc.).

Model and Specifications: FRP Specifications NCHJL-B-200-1500. Filter diameter ranges from 200-1500mm.

Carbon steel, Stainless Steel SUS304, specification NCHJL-T-200-3000. Filter diameter ranges from 200-3000mm.

Based on your actual water usage, we will assist you in selecting the appropriate specifications and materials.

2. Active Carbon Filter

Craft characteristics: Activated carbon filters are primarily used for吸附 watercolor, taste, residual chlorine, organic matter, and colloidal substances; they also serve to filter out large particles. They can be equipped with pasteurization to enhance the lifespan of the activated carbon and reduce bacterial growth during the production process.

Materials include: fiberglass, carbon steel (with internal corrosion protection), and stainless steel SUS304 (lined with rubber corrosion protection), catering to various industry production and process requirements.

Control Methods: Manual Operation, Semi-Automatic, Full Automatic (including automatic control valves, pneumatic valve groups, and electric valve groups, etc.).

Model and Specifications: FRP Specifications NCHTL-B-200-1500. Filter diameter ranges from 200-1500mm.

Carbon steel, stainless steel SUS304 specification NCHJL-T-200-3000. Filter diameter from 200-3000mm.

3. Demineralizer

Process Features: The softener, also known as a sodium ion exchange unit, effectively removes Ca2+ and Mg2+ from the water during the production process, reducing water hardness. This prevents the formation of carbonate and sulfate scales in the process, and the resin can be regenerated and reused. The softener can be used for boiler water softening and as a pre-treatment for reverse osmosis.

Materials include: fiberglass, carbon steel (internally lined for corrosion resistance), and stainless steel SUS304 (lined with rubber for corrosion resistance), catering to different industry production and process requirements.

Control Methods: Manual Operation, Semi-Automatic, Fully Automatic (with automatic control valves, pneumatic valve groups, and electric valve groups, etc.).

Model and Specifications: Glass Reinforced Plastic (GRP) specification NCHTL-B-200-1500. Filter diameter ranges from 200-1500mm.

Carbon steel, Stainless Steel SUS304 specification NCHJL-T-200-3000. Filter diameter from 200-3000mm.

4. Filter Cartridge Housing

Process Features: The filter, also known as a fine filter in the water system, is typically achieved by a polypropylene (PP) membrane with a melt-blown pore size of 5µm. Fine filtration is a pre-treatment process before the raw water enters the reverse osmosis membrane. Its function is to prevent any leakage from the previous filtration step, ensuring the long-term stable operation of the reverse osmosis system.

Materials include: fiberglass, carbon steel, and stainless steel SUS304, catering to the production and process requirements of various industries.

Model and Specifications: Glass Reinforced Plastic (GRP) specification NCHTL-B-200-1000. Filter diameter ranges from 200-1000mm.

Carbon steel, Stainless Steel SUS304, specification NCHJL-T-200-1500. Filter diameter: 200-1500mm.
