Description
Technical Field
The utility model relates to a waterway system and water purifier.
Background
The theory of dissolution-diffusion considers that the RO membrane is a non-porous complete membrane, solutes such as water molecules and salts can be dissolved in the membrane, and the water molecules and solute molecules dissolved in the membrane can diffuse to the other side of the RO membrane under the action of external pressure, but the diffusion speeds are different. When water is normally produced, the diffusion speed of water molecules under the external pressure is far greater than that of solute molecules, so that the water molecules can rapidly permeate the RO membrane, most of the solute molecules can be enriched on the raw water side, and the solute molecules and the water molecules are separated; this results in an increase in the pure side water TDS (Total dissolved solids, also known as Total dissolved solids, measured in milligrams per liter (mg/L), which indicates how many milligrams of dissolved solids are dissolved in 1 liter of water, and higher TDS values indicate more dissolved material in the water). Therefore, when the water purifier produces water again, the first cup of water taken by a user is the water with a high TDS value flowing out of the RO membrane element, and the water quality can not meet the requirement.
