Deionized water equipment for the fine chemical industry is custom-designed to produce deionized water tailored to the needs of the fine chemical sector.

Features

- High precision: Effectively removes various ions from water, with effluent conductivity often reaching very low levels, such as less than 0.1 μS/cm, meeting the extremely high purity requirements of the fine chemical industry.
- Flexible process combination: Often employs a combination of multiple water treatment processes. For example, in addition to basic ion exchange resin treatment, technologies like reverse osmosis and ultrafiltration are integrated to address complex raw water quality and diverse production water needs.
- High-quality materials: Components in contact with water, such as pipelines and tanks, are generally made of corrosion-resistant materials like stainless steel 316L to prevent contamination of water quality.

Main Components

- Pretreatment unit: Includes multi-media filters (such as quartz sand and activated carbon) to remove suspended solids, organic matter, and residual chlorine from water, reducing turbidity and color of the raw water and easing the burden on subsequent treatment.
- Reverse osmosis system: Utilizes the principle of semi-permeable membranes to perform preliminary desalination of pretreated water, removing 95%–99% of salts and most impurities. This is a critical step in deionized water production.
- Ion exchange system: Typically uses mixed-bed ion exchange resins, where anion and cation exchange resins are mixed together to rapidly and thoroughly exchange the remaining anions and cations in water, further enhancing water purity.

Application Scenarios

- In paint production: Used to dilute paints, ensuring product quality and stability, and preventing issues such as precipitation or discoloration caused by ions in water.
- In cosmetics manufacturing: Used in the production of products like toners and lotions, providing consumers with safer and purer products.
