Evoqua (Formerly Siemens) Water Purification System
Features :
- Only new, specially selected and certified materials are used for the treatment steps in our ultrapure water systems.
- High quality, virgin electronic grade ion exchange resins are used in cartridges and systems. Resins and treatment media go through a rigorous R&D stage before approval for use to ensure high quality and zero leachable material that could interfere with water quality. Upon delivery, each resin must pass incoming quality control inspection tests. Materials are strictly stored and handled according to our standard operating procedure to prevent contamination.
- Carefully selected activated carbon is used in the systems to produce pure water with extremely low organic contaminants. However, different types are available depending on the required water quality or application.
- All activated carbon materials undergo a complete cleaning process prior application to remove particles and impurities. This involves an acid wash followed by rinsing the carbon with ultrapure water.. All wetter parts within the systems are specially selected and tested to ensure purity. Tests are performed to determine there are no extractable metals or TOC released from the water contact parts.
- The purification modules are accurately designed to ensure complete wetting of the activated carbon to remove entrained air and purge the systems.
- Mixed bed resin modules must have the correct moisture content and fill level to ensure quality & operating capacity. Rapid filling of the modules is essential to prevent excess air contact and avoid the uptake of carbon dioxide.
- An environment free of organic contaminants during the cartridge filling process plays a vital role in producing ultrapure water. Modules are sealed with airtight end caps to prevent drying and are shrink-wrapped to prevent contamination.
- Modules should be stored in a cool, dry location (< 20 °C) away from light.
