The working principle of automatic water purification equipment is mainly based on technical means such as physical filtration, chemical adsorption, and reverse osmosis.
Physical filtration: Blocking impurities in water through the pore size of the filter element. Common physical filtration methods include coarse filtration, fine filtration, and ultrafiltration. Coarse filtration is mainly responsible for removing large particle impurities such as sediment and rust; Fine filtration further removes small particulate matter and some microorganisms; Ultrafiltration has higher filtration accuracy and can intercept small particles and bacteria.
Chemical adsorption: Using the microporous structure of adsorbent materials (such as activated carbon filters) to adsorb harmful substances such as organic matter and residual chlorine in water. Activated carbon filter has a rich microporous structure, which can efficiently adsorb impurities in water and improve water quality.
Reverse osmosis (RO) technology: one of the most advanced water purification technologies currently available. RO membrane is a semi permeable membrane with a pore size of only 0.1 nanometers, which can effectively remove impurities such as dissolved salts, colloids, bacteria, viruses, bacterial endotoxins, and most organic matter from water. By increasing water pressure, water molecules pass through the RO membrane while harmful substances are trapped on the other side of the membrane, thus achieving the goal of water purification.
