Ultrapure water equipment is a device used to prepare high-purity water. Its main purpose is to remove impurities, ions, microorganisms and other pollutants in water to meet the high requirements for water quality in different fields. Such equipment usually adopts a series of advanced technologies such as filtration, reverse osmosis and distillation to ensure that the purity of water meets high standards.The working principle of ultrapure water equipment mainly includes the following steps: first, remove large particles of impurities and suspended solids in water through a pretreatment unit; then, remove organic matter, residual chlorine and other chemical substances in water through an activated carbon adsorption unit; next, deeply purify water through a reverse osmosis membrane unit to remove ions and microorganisms; finally, disinfect and sterilize water through a post-treatment unit to ensure the safety and reliability of water quality.Ultrapure water equipment is widely used in va...

2025-12-31Whether the water produced by ultrapure water equipment is pure enough depends not only on the quality of the equipment, but also on four key links: "raw water, equipment parts, operation settings, and daily maintenance". Even a small problem in one link may cause the water quality to fail to meet the standards. The impact of each factor is explained in simple terms below:Raw Water Quality: No Matter How Powerful the Equipment Is, It's Hard to Save Poor "Raw Materials"Ultrapure water is purified from raw water (such as tap water, well water). The amount of impurities in the raw water directly determines the difficulty of purification:Hard Water or Water with High Impurities: Well water and groundwater are often "hard water" (containing more calcium and magnesium ions), or raw water with high dissolved salts will form a layer of "scale" on the surface of the RO membrane (core filter component) in the equipment. This scale will block the small ...
2026-01-081.Pretreatment Unit: The First Line of Defense to Protect Core ComponentsPretreatment needs to remove impurities in raw water to avoid blockage or damage to subsequent equipment. Four types of components need to be maintained:Quartz Sand Filter: Backwash once every 1-2 months (pressure 0.2-0.3MPa, duration 15-20 minutes) to rinse the intercepted sediment and colloids; replace the quartz sand every 1-2 years (shorten the cycle when the raw water turbidity >5NTU) to ensure the effluent turbidity <1NTU and prevent RO membrane blockage.Activated Carbon Filter: Backwash once a month, replace the activated carbon every 6-12 months (replace in advance if the effluent residual chlorine >0.1mg/L); select food-grade carbon with an iodine value ≥1000mg/g, and regularly detect the effluent TOC to avoid releasing organic matter to pollute water quality after adsorption saturation.Softening Resin Filter: Regenerate with 8%—10% industrial salt water every 3-6 months (soak for 4-6 hour...
