Features of ultra-pure water equipment in the steel industry

Thread Content

　　The steel industry’s ultra-pure water treatment equipment continuously incorporates advanced foreign technologies and uses high-quality components from abroad, thereby ensuring the quality of the equipment, as well as its efficiency and the quality of the water produced. 　　Process flow of ultra-pure water equipment in the steel industry:
1. Pretreatment – Reverse osmosis – Purification tank – Ion exchanger – UV lamp – Pure water pump – Water usage point
2. Pretreatment – Primary reverse osmosis – Secondary reverse osmosis (positively charged reverse osmosis membrane) – Purification tank – Pure water pump – UV lamp – Water usage point
3. Pretreatment – Reverse osmosis – Intermediate tank – Intermediate water pump – EDI unit – Purification tank – Pure water pump – UV lamp – Water usage point
4. Pretreatment → Built-in UV sterilization device → Primary RO unit → Secondary RO unit → Intermediate tank → EDI unit → Deoxidation device → Nitrogen-sealed purification tank → TOC removal UV device → Polishing mixed bed → Ultrafiltration unit → Water usage point

The water quality meets the American ASTM standards as well as the electronic industry’s standards for ultra-pure water (four levels: 18 MΩ*cm, 15 MΩ*cm, 2 MΩ*cm, and 0.5 MΩ*cm). 　　Features of ultra-pure water equipment in the steel industry: 1. It occupies less space, as it eliminates the need for mixed-bed and regeneration units. 　　2. The produced water is continuous and stable, with high quality; whereas in mixed-bed systems, the water quality deteriorates as the resin approaches its end of life. 　　3. Low operating costs: regeneration requires only electricity, no acids or bases are needed, thus saving on material costs. 　　4. The environmental benefits of ultra-pure water equipment in the steel industry are significant, enhancing operational safety. 　　Laitlead Hefei Water Treatment Equipment Company [www.hefeishui.com] provides professional ultra-pure water equipment solutions for the steel industry. The ultra-pure water treatment equipment provided by LiteLead utilizes advanced reverse osmosis and EDI technologies; it not only ensures the high quality of water output for use in the steel industry but is also environmentally friendly and energy-efficient, which has earned it popularity among many users. 　　I hope we can learn from each other, discuss together, and make progress as a group.
