| Produce discharge (ml/min) | 150 | 150 | 150 | 150 | 150 | 150 |
| Return flow (ml/min) | 0 | 50 | 100 | 150 | 200 | 250 |
| System's flooding velocity (ml/min) | 450 | 400 | 350 | 300 | 250 | 200 |
| Reverse-osmosis membrane element flooding velocity (ml/min) | 450 | 450 | 450 | 450 | 450 | 450 |
| Wastewater flow (ml/min) | 300 | 250 | 200 | 150 | 100 | 50 |
| Reverse-osmosis membrane element producing water ratio (%) | 33 | 33 | 33 | 33 | 33 | 33 |
| Total producing water ratio (%) | 33 | 37.5 | 42.8 | 50 | 60 | 75 |
Producing water ratio=product discharge/flooding velocity * 100%
2, in further improvement of the utility model, increased the water softening filter core, the water softening filter core can be converted to soluble salt such as muriate etc. with difficulty soluble salt such as carbonate, vitriol etc. in water inlet and the recovery condensed water, thereby has guaranteed that the obstruction and the pollution of membrane element can not take place under the running condition of condensed water high-recovery and water purifier high yield water rate reverse-osmosis membrane element.
3, in further improvement of the present utility model, regeneration salt tank and regeneration magnetic valve on the condensed water return line, have been increased, when the usefulness of soften resin in the water softening filter core is used up, by in the regeneration salt tank, adding sodium-chlor, sodium-chlor and through water dissolution, flow into and make soften resin regeneration in the water softening filter core, thereby recover the water softening function of water softening filter core, make constantly softening water of water softening filter core.
