Natural water contains a high amount of impurities, making a pretreatment system before reverse osmosis indispensable. A well-prepared pretreatment system not only ensures the long-term stable operation of subsequent equipment but also operates safely for an extended period. Depending on the water quality, pretreatment options include multimedia filters, activated carbon filters, filters, softeners, iron and manganese removal filters, and disk filters, among others.
1. Multi-Media Filter
Process Features: Multi-media filters, also known as mechanical filters, primarily retain physical impurities in water, removing suspended matter, solid particles, and some colloidal substances.
Materials include: fiberglass, carbon steel (internal anti-corrosion), and stainless steel SUS304 (lined with rubber for anti-corrosion), catering to various 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: FRP Specifications 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 assist 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. They can be equipped with pasteurization to extend the lifespan of the activated carbon, reducing 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, Fully Automatic (including automatic control valves, pneumatic valve groups, and electric valve groups, etc.).
Model and Specifications: Glass fiber 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, 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 scale in the water, and the resin can be regenerated for reuse. The softener can be used for softening boiler water and as a pretreatment for reverse osmosis.
Materials include: fiberglass, carbon steel (with internal anti-corrosion), and SUS304 stainless steel (lined with rubber for anti-corrosion), capable of meeting 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 (Fiberglass Reinforced Plastic) Specifications NCHTL-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.
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 melt-blown polypropylene (PP) membrane. Fine filtration is a pretreatment process before the raw water enters the reverse osmosis membrane. Its function is to prevent any leakage 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, capable of meeting the production and process requirements of various industries.
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 ranges from 200-1500mm.
