Y-Type Filter

I. Overview of Reverse Osmosis Systems

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

1. Multi-Media Filter

Process Features: Multi-medium filters, also known as mechanical filters, primarily trap 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 anti-corrosion), capable of meeting the production and process requirements of various industries.

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

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

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

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

2. Active Carbon Filter

Process Features: Activated carbon filters are primarily used to adsorb color, taste, residual chlorine, organic matter, and colloidal substances in water; they also serve to filter out large particle impurities. Pasteurization can be added to extend 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), which can meet the production and process requirements of various industries.

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

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

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

3. Demineralizer

Process Features: The softener, which is a sodium ion exchange unit, effectively removes Ca2+ and Mg2+ from the water during production, thereby reducing the water hardness. This prevents the formation of carbonate and sulfate scale during production. The resin can be regenerated and recycled. The softener can be used for softening boiler water and as pretreatment for reverse osmosis.

Materials include: fiberglass, carbon steel (internally lined for corrosion resistance), and stainless steel SUS304 (lined with rubber for corrosion resistance), which can meet the production and process requirements of various industries.

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

Model and Specifications: Glass Fiber 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: 200-3000mm.

4. Filter Cartridge, Filter Housing

Process Features: The filter, also known as a fine filter in the water system, is typically achieved by a 5µm aperture polypropylene (PP) membrane formed through meltblowing. Fine filtration is a pretreatment process before the reverse osmosis membrane. Its function is to prevent any leakage from the previous filtration stage, ensuring the long-term stable operation of the reverse osmosis system.

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

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.
