A reverse osmosis membrane direct drinking machine

technical field

However, the current household direct-drinking reverse osmosis water purification equipment generally has water storage tanks or similar devices. Since the pure water entering the water storage tank lacks residual chlorine or other disinfection methods, the pure water is prone to dehydration when not used for a long time. At the same time, because the inner liner of the water storage tank is usually made of rubber, rubber product additives are easy to precipitate and cause secondary pollution of water; and when the reverse osmosis drinking machine stops working, the concentrated water side pressure decreases, due to The water concentration is high. Driven by osmotic pressure, the water molecules on the product water side will move to the concentrated water side through the reverse osmosis membrane, and the water volume on the product water side will decrease, resulting in the actual concentration of the product water and the increase of the salt content. ;

When the direct drinking machine is stopped for a period of time and then restarted, the salt content of the wastewater on the concentrated water side is relatively high. Driven by pressure, the water will move through the reverse osmosis membrane to the product water side, and the concentrated product water on the product water side and The newly produced water flows out together, and the first glass of water that the user drinks is often made before, resulting in a high salt content in the initial produced water, which cannot absolutely guarantee the health effect of drinking immediately after production.
