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, strictly separating pure water that can pass through from concentrated water that cannot.

Principle: Osmosis is a physical phenomenon where water from two bodies of water with different salt concentrations, separated by a semi-permeable membrane, will pass through the membrane until the salt concentrations are equalized. However, this process takes a long time and is known as natural osmosis. If a pressure is applied to the side with higher salt concentration, it can stop the osmosis, and this pressure is called osmotic pressure. Increasing the pressure can cause water to渗透 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 water molecules to be pushed to the other side of the membrane, resulting in clean water. This process removes salt from the water, hence the principle of reverse osmosis desalination.

Reverse osmosis membranes utilize aromatic polyamide spiral wound composite membranes. The reverse osmosis system 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 for automatic operation. It's fitted 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 feed water from the previous stage to the user's required level, and also has certain control capabilities over TOC and SiO2.

Polished mixed bed ion exchange requires specific feedwater, which must be the product water from an anion, cation, or mixed bed ion exchange system, or from a continuous EDI (Electrodeionization) salt removal system. Only under feedwater conditions that meet these requirements can the polished mixed bed ion exchange operate stably and long-term.
