Description

Waterway system and water purifier with same

Technical Field

The utility model relates to the field of water purification waterway, in particular to a waterway system and a water purifier with the same.

Background

In the theory of dissolution-diffusion, the RO membrane is considered to be 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 normal system water, the diffusion velocity of hydrone under ambient pressure will be far greater than the diffusion velocity of solute molecule, therefore the hydrone can permeate the RO membrane rapidly and most solute molecule can be at the raw water side enrichment to the realization is to the separation of solute molecule and hydrone, however, when the water purifier shut down and is stood for a long time, the solute molecule concentration of raw water side is far higher than the pure water side, can take place the solute diffusion under the concentration gradient drive, the solute molecule can permeate the RO membrane gradually, and finally reach diffusion balance. This results in an increase in the pure water 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. Therefore, when the water purifier produces water again, the first cup of water that the user received is the water of the high TDS value that flows out from the RO membrane element promptly, and quality of water can't satisfy the demands.
