Disc tube reverse osmosis（DT）
Disc tube reverse osmosis is a membrane module specifically designed for treating high concentration wastewater, with the core technology being a disc tube type membrane column. Stack the diaphragm and hydraulic guide plate together, fix them with a central pull rod and end plate, and then place them in a pressure-resistant sleeve to form a membrane column.
