Electronic Semiconductor Industrial Solutions
1. Multiple media/activated carbon filtration systems:
In the manufacturing industry
Multimedia filters are typically used in the initial stage of water treatment, effectively removing suspended solids, colloids, particles, and various impurities from water through a combination of multiple media, providing clean water for subsequent treatment. This step is crucial for protecting subsequent processing equipment and improving overall processing efficiency.
Activated carbon filters are mainly used to remove organic matter, odors, pigments, and other impurities from water. Activated carbon has strong absorption capacity, which can absorb and remove pollutants from water, thereby improving the purity of water. This step is crucial for ensuring the quality and stability of ultrapure water.
By combining multimedia filters and activated carbon filters, you can effectively remove most impurities from water for further advanced treatment (such as reverse osmosis, ion exchange, etc.), providing good basic quality. This helps to ensure the quality and stability of ultrapure water required in the production process of the electronic semiconductor industry, in order to improve product performance and reliability.
Technical Principles
The principle of multimedia filtering technology is mainly to use one or more filtering media for deep filtration to remove liquid impurities in water. When the raw water passes through the filter material from top to bottom, large particles are removed at the top layer, while small particles are removed deeper in the filter medium. This mainly depends on the absorption and mechanical resistance of the filter material layer, as well as the compactness of the sand particle arrangement, making the particles in the water more likely to collide with the sand particles and be blocked. After this treatment, the liquid on the water can be kept at a lower level to ensure the clarity of the water quality.
The technical principle of activated carbon filters is mainly based on the absorption of activated carbon. Activated carbon has a huge surface area and complex pore structure, which gives it strong absorption capacity. When water passes through an activated carbon filter, organic matter, odor, color, and other pollutants in the water are absorbed by the surface of the activated carbon and effectively removed. In addition, activated carbon can also remove chlorine from water to ensure the normal operation of subsequent treatment equipment.
What achievements can we achieve?
Firstly, multimedia filters are used as preprocessing devices, and their design of multiple combination media enables them to effectively remove adhesives, particles, and large impurities from water. This is crucial for protecting subsequent water treatment equipment and processes to ensure the stable operation of the entire water treatment system. Through this step, initial clean water can be provided for the electronic semiconductor industry, reducing the potential impact of impurities on the production process.
Secondly, filter activated carbon utilizes its strong absorption capacity to further remove impurities such as organic matter, odor, and pigment from water. If these impurities are not removed, they may have adverse effects on the quality and performance of electronic semiconductor products. The application of activated carbon filtration can greatly improve the purity of water and meet the strict requirements of the high-quality electronic semiconductor industry.

Technical Principles
Reverse osmosis membrane is usually a synthetic semi permeable membrane with a very small size, which can effectively prevent impurities such as salt, organic matter, and heavy metal ions from decomposing in water, while allowing water molecules to pass through. If a pressure greater than the osmotic pressure is applied on one side of the thick solution, the solvent will flow in the opposite direction to the original osmotic direction and begin to flow from the thick solution to the dilute solution side. This process is called reverse osmosis. At this point, the solvent under pressure passes through the reverse osmosis membrane, and the solution is blocked by the membrane to achieve separation and purity.

Under the influence of DC field, dielectric ions in the partition of EDI system move in the direction. Ion exchange membranes can selectively pass through ions, allowing some ions to pass through and preventing others from passing through to clean water quality. In this process, the ion exchange resin is continuously regenerated by electricity, so there is no need for acid and potassium regeneration.
Specifically, the EDI module clamps the EDI unit filled with ion exchange resin between ion/negative exchange membranes into the EDI unit, which is separated by a mesh panel to form a water and fresh water chamber. After placing the anode/cathode at both ends of the part, direct current will push the positive and negative ions flowing through the corresponding ion exchange membrane into the water storage chamber to eliminate these ions in the fresh water chamber. The water in the thickened water chamber can take ions away from the system and produce thickened water.
