This diagram illustrates the complete water flow path of a 5-stage deep purification system:

1. Water Inlet → PP (sediment filtration)
2. → UDF (granular activated carbon adsorption)
3. → PP (fine filtration)
4. → RO (reverse osmosis membrane purification)
5. → UDF (post-carbon polishing) → Water Outlet

A separate Drain Outlet channels wastewater away, ensuring efficient separation and delivering thoroughly purified water.
