1. Raw water pump. 2. Raw water tank. 3. Quartz sand: removes large suspended particles from water. 4. Activated carbon: removes some discoloration and odor. 5. Scale inhibition equipment: prevents the binding of calcium and magnesium ions in water, preventing the formation of scale. 6. Security filter: deeply filters impurities in water and removes discoloration. Filtering accuracy: 5 microns. 7. High pressure pump: using high-strength water pressure to transport water into the reverse osmosis membrane. 8. Reverse osmosis: a membrane with a pore size of 0.0000001 microns that intercepts small impurities in water. The effluent is pure water. 9. Pure water tank. Stainless steel water tank, water quality is not prone to secondary pollution
