Description

Water system and water purification equipment

technical field

The invention relates to the technical field of water purification equipment, in particular to a waterway system and water purification equipment.

Background technique

The dissolution-diffusion theory believes that the RO membrane is a non-porous and complete membrane. Solutes such as water molecules and salts can be dissolved in the membrane. The water molecules and solute molecules dissolved in the membrane will move to the RO membrane under the action of external pressure. Lateral diffusion, but the diffusion speed is different. During normal water production, the diffusion speed of water molecules under external pressure is much greater than the diffusion speed of solute molecules. Therefore, water molecules will quickly pass through the RO membrane and most of the solute molecules will be enriched on the raw water side, so as to realize the elimination of solute molecules. separation of water molecules.

However, when the water purifier is shut down for a long time, the concentration of solute molecules on the raw water side is much higher than that on the pure water side, solute diffusion will occur under the drive of the concentration gradient, and the solute molecules will gradually penetrate the RO membrane and eventually reach the diffusion balance. This results in a water TDS (Total dissolved solids) on the pure water side. . The higher the TDS value, the more dissolved substances contained in the water. ) increased. Therefore, when the water purifier makes water again, the first cup of water that the user receives is the high TDS water flowing out from the RO membrane element, and the water quality cannot meet the requirements.
