Wesight - Water Treatment Ultra-Pure Water Equipment: Refers to water with a resistivity of 18 MΩ*cm (at 25℃). This water, besides water molecules, contains almost no impurities, no organic matter, and of course, no trace minerals needed by the human body, meaning it removes almost all atoms except oxygen and hydrogen. It can be used in the preparation processes for ultra-pure materials (such as semiconductor materials, nano-fine ceramic materials, etc.), including distillation, deionization, reverse osmosis technology, or other appropriate ultra-critical fine technologies. The methods for separating and recovering non-dissolved suspended pollutants in wastewater (including oil films and oil droplets) through physical means can be divided into gravity separation, centrifugal separation, and sieve filtration retention methods. Treatment units belonging to the gravity separation method include sedimentation, floating (air flotation), etc., with corresponding equipment such as sand traps, sedimentation basins, grease traps, air flotation basins, and their auxiliary facilities.
