In the electronic chip manufacturing industry, the requirements for the quality of production water are extremely strict. Even minor fluctuations in water quality can affect the performance and yield rate of chips. The reverse osmosis equipment produced by [Company Name], with its advanced technology and stable and reliable performance, has become a key choice for many electronic chip manufacturing enterprises to improve production quality. The following takes the actual project of a well - known electronic chip manufacturing enterprise as an example to introduce the application of our company's reverse osmosis equipment in detail.
I. Project Background
A well - known electronic chip manufacturing enterprise focuses on the research, development, and production of high - end chips, with an average monthly chip output of 100,000 pieces. The enterprise's original water treatment system combined the traditional ion - exchange resin method with simple filtration, which was difficult to meet the increasingly stringent production water standards. According to tests, in the water produced by the original system, the total dissolved solids (TDS) content was as high as 50mg/L, and the microbial content sometimes exceeded the standard, with the total number of bacteria reaching up to 100CFU/mL at its highest. These impurities could cause problems such as surface defects and short circuits in the chip during key manufacturing processes like photolithography and etching, resulting in the chip yield rate remaining around 80% for a long time, severely restricting the enterprise's production efficiency and market competitiveness. To solve this problem and improve chip production quality, the enterprise decided to introduce advanced reverse osmosis equipment to upgrade the water treatment system. After multiple rounds of comparison and investigation, it finally chose the reverse osmosis equipment of our company.
II. Application and Implementation of Our Company's Reverse Osmosis Equipment
(I) Equipment Selection and Customization
The technical team of our company deeply understood the special requirements of the enterprise's chip manufacturing process for water quality and, combined with the enterprise's water consumption scale, customized a large - scale reverse osmosis equipment system for it. The core reverse osmosis membrane adopted the aromatic polyamide composite membrane independently developed by our company. This membrane has the characteristics of high salt rejection rate, large water production, and strong anti - pollution ability, with a salt rejection rate of over 99.8%. It can effectively remove various ions, organic substances, and microorganisms in water. The designed water production capacity of the entire set of equipment is 50 tons per hour, which can meet the continuous water demand of the enterprise's chip manufacturing workshop.
(II) System Installation and Debugging
Pretreatment System: A complete pretreatment system was built in front of the reverse osmosis equipment, including multi - media filters, activated carbon filters, fine filters, and water softeners. The multi - media filter removes larger suspended solids and colloids in water through quartz sand, anthracite, and other filter materials of different gradations; the activated carbon filter uses its strong adsorption capacity to remove residual chlorine, pigments, and some organic substances in water; the fine filter uses 5 - micron filter elements to further intercept tiny particles; the water softener reduces water hardness through ion - exchange resins, preventing the reverse osmosis membrane from scaling and providing high - quality inlet water conditions for the reverse osmosis membrane.
Reverse Osmosis Main Unit: The reverse osmosis main unit is composed of multiple membrane elements connected in series and parallel, adopting the cross - flow filtration method, effectively reducing the concentration polarization phenomenon on the membrane surface and improving the desalination efficiency. The equipment is equipped with an intelligent control system that can real - time monitor and adjust parameters such as inlet pressure, flow rate, pH value, and temperature. When abnormalities occur in the system, it can automatically alarm and take corresponding protective measures to ensure stable operation of the equipment.
Post - treatment System: To further improve water quality and meet the special requirements of chip manufacturing, a post - treatment system was also configured, including ultraviolet sterilizers and polishing mixed beds. The ultraviolet sterilizer destroys the DNA structure of microorganisms in water through ultraviolet irradiation, killing residual bacteria and viruses; the polishing mixed bed uses anion and cation exchange resins to deeply remove trace ions remaining in water, making the water quality reach the ultra - pure water standard.
After the equipment installation was completed, the professional technicians of our company carried out a two - week debugging work, finely adjusted various parameters of the system, and provided comprehensive operation training and maintenance guidance for the enterprise's operators to ensure the smooth operation of the equipment.
III. Application Effects
Effect Category | Specific Performance |
Significant Improvement in Water Quality | - The total dissolved solids (TDS) content is reduced to below 0.5mg/L, meeting the strict requirements for ultra - pure water in electronic chip manufacturing - The microbial content is almost undetectable, with the total number of bacteria less than 1CFU/mL, effectively avoiding the pollution of microorganisms to chip production - The concentration of various ions in water is greatly reduced, and the removal rate of heavy metal ions is over 99.9%, providing high - quality water for chip manufacturing |
Remarkable Increase in Production Efficiency | - The chip yield rate has increased from the original 80% to 92%. An additional 12,000 qualified chips can be produced per month, with an annual increase in output value of approximately 120 million yuan - The equipment has a high degree of automation, reducing manual operation links and labor intensity, saving about 1.5 million yuan in labor costs annually - The equipment operates stably, and the maintenance cycle has been extended from once a month to once every six months. The maintenance time has been greatly shortened, effectively guaranteeing production continuity, and the annual equipment downtime has been reduced by about 80 hours |
Effective Cost Reduction | - The service life of the reverse osmosis membrane is as long as 3 - 5 years. Compared with traditional water treatment consumables, about 2 million yuan in consumable costs can be saved annually - Energy consumption has been optimized. By using energy - efficient pumps and optimizing system operation parameters, 15% of electricity can be saved for every ton of ultra - pure water produced, saving about 800,000 yuan in electricity bills annually |
