Disc filter

I. Overview of Reverse Osmosis Systems

High levels of impurities are commonly found in natural water, making a pretreatment system before reverse osmosis essential. A well-designed pretreatment system not only ensures long-term stable operation for the subsequent equipment but also operates safely and efficiently for an extended period. The choice of pretreatment depends on the water quality and may include multimedia filters, activated carbon filters, filters,软化ers, iron and manganese removal filters, and disc filters, among others.

1. Multi-Media Filter

Process Features: Multi-medium 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 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, 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 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 absorb color, taste, residual chlorine, organic matter, and colloidal substances in water; they also serve to filter out large particles of impurities. They can be equipped with pasteurization to extend the lifespan of the activated carbon, reducing the proliferation of bacteria during the production process.

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 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 from 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, thereby reducing water hardness. This prevents the formation of carbonate and sulfate scale in the production process. The resin can be regenerated and reused. The softener can be used for softening boiler water and as a pretreatment for reverse osmosis.

Materials include: fiberglass, carbon steel (internally lined with anti-corrosive coating), and stainless steel SUS304 (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 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 precision filter in the water system, is typically achieved by a 5µm polypropylene (PP) membrane formed through meltblowing. Precision filtration is the first treatment process before the raw water enters the reverse osmosis membrane. Its function is to prevent leaks that may exist in 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: Glass Reinforced Plastic (GRP) 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.
