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 long-term stable operation of the subsequent equipment but also operates safely for a long duration. The choice of pretreatment varies according to water quality and includes multi-media filters, activated carbon filters, sediment filters, softeners, iron and manganese removal filters, and disc filters, among others.
1. Multi-Media Filter
Process Features: Multi-media filter, also known as mechanical filter, primarily intercepts 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 anti-corrosion rubber), which can meet the production and process requirements of various industries.
Control Methods: Manual Operation, Semi-Automatic, Fully Automatic (with Automatic Control Valves, Pneumatic Valve Groups, and Electric Valve Groups, etc.).
Model and Specifications: Glass Fiber Reinforced Plastic (GFRP) 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
Process Features: Activated carbon filters are primarily used to adsorb color, odor, 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 enhance the lifespan of the activated carbon, reducing bacterial growth during the production process.
Materials include: fiberglass, carbon steel (with 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: 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 production process. The softener can be regenerated with resin and reused. It can be used for softening boiler water and as pretreatment for reverse osmosis.
Materials include: fiberglass, carbon steel (with internal anti-corrosion), and stainless steel SUS304 (lined with anti-corrosion rubber), 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) 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.
4. Filter Cartridge Housing
Process Features: The filter, also known as a precision filter in the water system, is typically made of a 5µm melt-blown polypropylene (PP) membrane. Precision filtration is a treatment process prior to the reverse osmosis membrane. Its function is to prevent leaks 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, capable of meeting the production and process requirements of various industries.
Model and Specifications: Glass Fiber Reinforced Plastic (GFRP) specifications NCHTL-B-200-1000. Filter diameter ranges from 200-1000mm.
Carbon steel, Stainless Steel SUS304, specification NCHJL-T-200-1500. Filter diameter: 200-1500mm.
