The wastewater treatment process for solar cell wafer manufacturing involves the treatment of wastewater containing various components generated from the processing of used slurry. The wastewater mainly contains oils, acids, alkalis, and heavy metals, and may also contain a significant amount of solids. To dispose of such wastewater in accordance with legal regulations or to discharge it into the sewage system, appropriate pretreatment is necessary. By filtering and neutralizing the raw water and then passing it through a reverse osmosis system, it can be discharged into the sewage system.

• Wastewater/wastewater treatment equipment

"Process water" is an important factor that influences systems in the industrial sector, requiring water with appropriate quality that has specific chemical properties suitable for particular processes and does not damage equipment components. Our company provides highly reliable valves suitable for handling various types of process water and chemical agents.

• Water treatment equipment

The power plant has various process water circuits, and corresponding purification treatment of raw water and pre-treatment for discharging wastewater into the sewer are necessary. Our company provides valves for supplying water to various treatment processes.

• Other water treatment equipment

In boiler equipment, corrosion and sedimentation caused by dissolved salts in water are problematic. To avoid these issues, various requirements are imposed on the quality of boiler water based on the operating methods and structure of the steam generation equipment. Our company provides valves for supplying water and chemicals to boilers.

• Other water treatment equipment

Pure steam refers to sterilization steam, while ultra-pure steam refers to pure steam used in the pharmaceutical industry. The 505 type is a valve specialized for controlling steam that requires high sterility. The spindle is sealed with a bellows, eliminating concerns about external contamination. In addition to its sanitary properties, it also features the compact design, high flow rate, durability, and good controllability characteristic of angle seat valves.

"Pure water and ultrapure water" are necessary in the pharmaceutical and biotechnology industries for the production of pharmaceuticals and materials, as well as in the microelectronics and semiconductor industries. Since pure water significantly affects product quality and manufacturing process efficiency, the plant components are subject to extremely strict requirements. Our company offers diaphragm valves specifically designed for use in ultrapure water treatment and supply equipment, as well as process equipment.

• Other water treatment equipment

Ultra-pure water (UPW) is widely used in the manufacturing processes of semiconductor and solar cell wafers. The abrasives that adhere to the wafer surface are removed during the cleaning process and are washed again with ultra-pure water in the final stage. Cleaning with ultra-pure water is also necessary to remove residues generated during the subsequent etching process. Maintaining the wafer surface clean during such manufacturing processes leads to maximizing power generation efficiency. We offer diaphragm valves specifically developed for the treatment and supply of ultra-pure water, as well as for use in process equipment.

• Pure water production equipment

Pure steam refers to steam used for sterilization, while ultra-pure steam refers to pure steam used in the pharmaceutical industry. The 555 type is a valve specialized for controlling steam that requires high sterility. The spindle is sealed with a bellows, eliminating concerns about external contamination. In addition to its sanitary properties, it also features the compactness, high flow rate, durability, and good controllability characteristic of angle seat valves.

The 650TL type safe sampling valve is used at sampling points and use points. It is a manual valve, but it can only be opened and closed when operating air is supplied; the valve remains closed when operating air is not supplied. Due to the air switching, it is possible to lock the handle remotely, allowing the timing of sampling at each site to be controlled by a central management system.

The production of water for injection (WFI) uses multi-purpose can-type and thermal compression distillers according to the required amount and temperature of distilled water. The "thermal compression" method pressurizes the generated steam using a heat pump, raising the temperature from 100°C to 140°C, and utilizes it for heating the supply water. We offer diaphragm valves specifically developed for use in ultrapure water treatment and supply equipment as well as process equipment.

• Other water treatment equipment

"Highly purified water (HPW)" is generally produced in the final stage of manufacturing by removing particles, bacteria, and pyrogens, and by installing a membrane filtration system to maintain the quality of the purified water. "Purified water (PW)" is produced by combining membrane separation methods and ion exchange methods, while the electric regeneration type pure water device (EDI) combines both of these methods for production. We offer diaphragm valves specifically developed for use in ultra-pure water treatment and supply equipment, as well as process equipment.
