Two-Stage Reverse Osmosis Ultra-Pure Water Purification Equipment for Electronics Factories

● The two-stage reverse osmosis pure water treatment equipment adopts a dual water supply system, featuring two separate pipelines: one for domestic water—tap water, and the other for direct drinking water. Direct drinking water is purified using reverse osmosis technology and delivered directly to households through food-grade environmentally friendly pipes and a closed-loop special pipeline network. This method is widely adopted in developed countries such as the United States.

● Application scope of two-stage reverse osmosis pure water treatment equipment: 1. Preparation of pure water and ultra-pure water in industries such as electronics, food, and pharmaceuticals. 2. Purification and production of space water, distilled water, and water for food and beverage formulation. 3. Desalination of low-salinity brackish water and seawater.

● Typical process flow: Process one: Tap water pressure pump - multi-media filter - activated carbon filter - cation softener - safety filter - two-stage reverse osmosis unit - ozone generator - stainless steel water storage tank - variable frequency constant pressure water supply pump - water supply pipeline. Process one meets the national standard GB17323-1998 <>.

● Process two: Tap water pressure pump - multi-media filter - activated carbon filter - cation softener - safety filter - hollow fiber ultrafiltration membrane/reverse osmosis membrane/nanofiltration membrane - ozone generator - stainless steel water storage tank - variable frequency constant pressure water supply pump - water supply pipeline. Process two complies with the Ministry of Construction standard CJ94-1999 <>.
