Technical Field

[0001] This utility model relates to the field of disc tube reverse osmosis water treatment technology, specifically a disc tube reverse osmosis water treatment device. Background Technology

[0002] Disc-tube reverse osmosis water treatment is a water treatment process based on reverse osmosis technology, which purifies water through the pressure difference of a semi-permeable membrane. Its core structure consists of disc-shaped membranes, a flow guide plate, and O-ring rubber gaskets. It adopts an open flow channel design to enhance its anti-fouling ability and is suitable for treating highly polluted and high-salinity water bodies.

[0003] Disc tube reverse osmosis water treatment uses a high-pressure pump to pressurize water molecules and force them through a semi-permeable membrane, where solutes are retained, thus purifying the water. Its unique structure creates turbulent flow, reducing scaling and contamination. During operation, a flow guide plate is required, and its alignment during assembly is crucial. Insufficient alignment will directly impact the treatment effect. Utility Model Content
