How TM720D-400 RO Membrane Works
The TM720D-400 membrane works using reverse osmosis technology to remove dissolved solids and impurities from water.
Step 1: Water Enters the RO System
Feed water containing dissolved salts and impurities enters the RO pressure vessel containing the membrane.
Step 2: Pressure is Applied
High pressure pushes water through the semi-permeable membrane surface.
Step 3: Filtration Process
The membrane allows only pure water molecules to pass through while rejecting salts, heavy metals, and contaminants.
Step 4: Clean Water Output
The purified water is collected as permeate, while rejected contaminants are discharged as concentrate.
This advanced filtration process makes TM720D-400 highly effective for industrial water purification.
