[0035] Working principle: Raw water is pressurized from the raw water tank and flows sequentially into the composite filter 5, activated carbon filter 6, and water softener 8 to pre-treat the raw water, reducing suspended solids, colloids, and organic matter. Salt is then added in the water softener 8 to prepare for subsequent reverse osmosis treatment. The water then enters the booster tank 9 and is pressurized by the booster pump 8. Once a certain pressure is reached, the water flows into the pressure tank 12. After the pressure tank 12 reaches the predetermined pressure, the water enters the first reverse osmosis filter 3. After primary reverse osmosis treatment, the high-quality water and concentrated water are separated and flow out separately. The high-quality water enters the second-stage reverse osmosis filter 2 and undergoes secondary reverse osmosis treatment. Finally, the high-quality water and concentrated water flow into the pure water tank and concentrated water tank, respectively, for further treatment.
