Small Reverse Osmosis System

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 an extended period. The choice of pretreatment methods varies according to water quality, including multimedia filters, activated carbon filters, filters, softeners, iron and manganese removal filters, and disk filters, among others.

1. Multi-Media Filter

Process Features: The multi-media filter, also known as a mechanical filter, primarily intercepts 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), 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 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, 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 for 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) 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.

3. Demineralizer

Process Features: The softener, also known as a sodium ion exchange unit, effectively removes Ca2+ and Mg2+ ions from the water during the production process, thereby reducing water hardness. This prevents the formation of carbonate and sulfate scale in the production process. The softener can be reused through resin regeneration. It is suitable for softening boiler water and as a 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, Full Automatic (with automatic control valves, pneumatic valve groups, and electric valve groups, etc.).

Model and Specifications: Glass Fiber Reinforced Plastic (GFRP) 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, Filter 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 pretreatment 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 stable operation of the reverse osmosis system.

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

Model and Specifications: Glass fiber 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.
