I. Recommended Production Process:

1. Primary Reverse Osmosis RO: Water Conductivity ≤ 10 μS/cm (25°C)

Source water → Activated Carbon Filtration → 10um Filtration → 5um Filtration → High-Pressure Pump → First Stage Reverse Osmosis RO → Pure Water Tank → Transfer Pump → Water Usage Point

Note: If the raw water pressure is unstable, it is recommended to add a raw water tank and a raw water booster pump.

The process can be optionally equipped with an ultraviolet sterilization/ozonation sterilization unit.

2. Primary Reverse Osmosis RO + Secondary Mixed Bed: Product Water Resistivity ≥ 5 MΩ·cm (at 25°C)

Water source with pressure → Activated Carbon Filtration → 10um Filtration → 5um Filtration → High-pressure Pump → Primary Reverse Osmosis RO → Primary Polishing Mixed Bed → Secondary Polishing Mixed Bed → Precision Filter → High Purity Water Tank → Feed Pump → Water Usage Point

Note: If the raw water pressure is unstable, it is recommended to increase the raw water tank and the raw water booster pump.

The process can be optionally equipped with an ultraviolet sterilization/ozonation sterilization unit.

3. First-level reverse osmosis RO + Triple-stage mixed bed: Product water resistivity: 15-18 MΩ·cm (25℃)

Water source with pressure → Activated Carbon Filtration → 10um Filtration → 5um Filtration → High-pressure Pump → First-stage Reverse Osmosis RO → First-stage Polishing Mixed Bed → Second-stage Polishing Mixed Bed → Third-stage Polishing Mixed Bed → Fine Filter → Ultra-Pure Water Tank (recommended with Nitrogen Protection) → Transfer Pump → Water Usage Point

Note: If the source water pressure is unstable, it is recommended to increase the source water tank and source water booster pump.

The process can be equipped with an optional UV sterilization/ozonation sterilization device.

II. Core Process Introduction:

1. Reverse Osmosis (RO) System

Reverse osmosis membranes, also known as RO, are a high-tech membrane separation technology invented by Loeb and Sourirtajan of the University of California, Los Angeles in 1960. Their pore size is as small as nanometers (1 nanometer = 10^-9 meters). Under certain pressure, H2O molecules can pass through the RO membrane, while inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, and other impurities in the source water cannot pass through the RO membrane, thereby strictly separating pure water that can pass through from concentrated water that cannot.

Principle: Osmosis is a physical phenomenon where water molecules from two bodies of water with different salt concentrations, separated by a semi-permeable membrane, will move through the membrane to equalize the salt concentrations. However, this process takes a long time and is known as natural osmosis. If pressure is applied to the side with higher salt concentration, the osmosis can be stopped, and this pressure is called osmotic pressure. Increasing the pressure can cause the water to permeate in the opposite direction, leaving the salt behind. Therefore, the principle of reverse osmosis desalination is to apply a pressure greater than the natural osmotic pressure to saltwater (such as raw water), causing the osmosis to occur in the opposite direction. This forces the water molecules to the other side of the membrane, resulting in clean water, and thus removing the salt from the water. This is the principle behind reverse osmosis desalination.

The reverse osmosis membrane utilizes an aromatic polyamide spiral wound composite membrane. The reverse osmosis unit consists of composite membrane elements, high-pressure pumps, fiberglass pressure vessels, chemical cleaning equipment, supports, and an instrument control cabinet. Equipped with a local control panel, which houses various local instruments and control buttons. The reverse osmosis desalination unit is controlled by a PLC and operates automatically. It is also equipped with flowmeters, pressure gauges, conductivity meters, and more.

2. Polished Mixed Bed System

Polished mixed bed is generally used at the end of ultra-pure water treatment systems, based on the principle of resin ion exchange. The container is filled with non-regeneration polishing mixed bed nuclear-grade ion exchange resin, with ion forms being H and OH. As a terminal desalination unit, it can elevate the resistivity of the feedwater from the previous stage to the user's required level, and also has certain control capabilities over TOC and SiO2.

Polishing mixed床 ion exchange requires specific feedwater quality, which must be the product water from a positive, negative, or mixed bed ion exchange system, or from an EDI continuous electro-deionization system. Only when the feedwater meets these requirements can the polishing mixed bed ion exchange operate stably and long-term.
