Field installation of filters

I. Overview of Reverse Osmosis Systems

Natural water contains a high amount of impurities, making a pretreatment system before reverse osmosis indispensable. A well-designed pretreatment system not only ensures the long-term stable operation of subsequent equipment but also operates safely for an extended period. The choice of pretreatment depends on the water quality and includes multimedia filters, activated carbon filters, sediment filters, softeners, iron and manganese removal filters, and disk filters, among others.

1. Multi-Media Filter

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

Materials include: fiberglass, carbon steel (with internal corrosion protection), and stainless steel SUS304 (lined with rubber corrosion protection), capable of meeting the production and process requirements of various industries.

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

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

Carbon steel, stainless steel SUS304, specification NCHJL-T-200-3000. Filter diameter from 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 particles of impurities. Pasteurization can be equipped to enhance the lifespan of activated carbon, reducing bacterial growth during the production process.

Materials include: glass fiber reinforced plastic, carbon steel (internal anti-corrosion), and stainless steel SUS304 (lined with anti-corrosion material), 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: FRP 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.

3. Demineralizer

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

Materials include: fiberglass, carbon steel (with internal anti-corrosion), and stainless steel SUS304 (lined with rubber for anti-corrosion), catering to 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: FRP (Fiberglass Reinforced Plastic) Specifications NCHTL-B-200-1500. Filter diameter ranges from 200 to 1500mm.

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

4. Filter Cartridge, Filter Housing

Process Features: The filter, also known as a fine filter in the water system, is typically made of a 5µm aperture polypropylene (PP) membrane formed by meltblowing. Fine filtration is the first treatment process before the source water reaches the reverse osmosis membrane. Its function is to prevent leaks from the previous filtration stage, ensuring the long-term normal 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: FRP Specification NCHTL-B-200-1000. Filter diameter ranges from 200-1000mm.

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