Choosing a pure water system that suits your needs is an important decision, as different applications require different water quality standards. Here are some recommended steps for choosing a pure water system:
1. Clarify what type of water quality your application requires. Different applications require different water quality standards, for example, general laboratory work may require Type II pure water, while molecular biology or cell culture may require higher levels of ultrapure water (Type I). Ensure that you understand the minimum water quality standards required for your application.
2. Understanding water source quality: You need to understand the quality of your water source, as it can affect the performance of the pure water system. If there are specific pollutants or issues in your water source, you may need to consider additional pre-treatment steps.
3. Choose the appropriate pure water system: Based on your application needs and water source quality, choose the appropriate pure water system. Here are some common types of pure water systems:
Ultra pure water system: including reverse osmosis and other purification steps, suitable for applications that require highly pure water, such as molecular biology and cell culture.
Ion exchange resin system: used to remove specific ions, suitable for specific applications such as ion analysis.
Mixed bed ion exchange system: used for producing high-purity water, such as electronic grade water.
Additional equipment for pure water machine: Some applications may require additional equipment, such as TOC analyzer or microporous filter.
4. Maintenance and operating costs: Consider the operating costs of the system, including consumables replacement, maintenance, and calibration. The operating costs of different systems may vary.
5. Installation and Training: Consider the training needs for installing and operating pure water systems. Ensure that your staff understands how to operate and maintain the system correctly.
6. Budget: Consider your budget. Different types and scales of pure water systems have different prices, so it is necessary to find a balance between quality and performance.
