Purified water rate refers to the proportion of the total purified water in the total inflow after the municipal water is purified by reverse osmosis system.

If the effluent rate is 3:1, it means that 3 liters of tap water is needed to get 1 jin of pure water, and the remaining 2 jin of tail water will be wasted if it is not fully utilized. The water efficiency grade of direct drinking water machine can be divided into five grades according to the water purification rate. The corresponding water purification rates from grade 1 to grade 5 are 60%, 55%, 50%, 45% and 35% respectively.
