Automatically adjust, it is ensured that the water inlet chlorine content of first-stage reverse osmosis device 113 is less than 0.1ppm.
Contain substantial amounts of CO2 in natural water body, CO2 is dissolved in product water, serious influence product water conductivity, and counter-infiltration
Removal efficiency to CO2 is almost nil, in order that the CO2 contents in reverse osmosis produced water are as far as possible low, that is, improve and produces water quality, anti-stopping leak
The CO2 of dew causes too fast, the influence producing water water quality that later stage EDI potting resin fails, and NaOH adder 115 is to two grades of high pressures
The inlet flow-patterm of pump 116 adds alkali to adjust to 8.2 or so, it is possible to prevent CO2 from passing through reverse osmosis membrane, all of under the conditions of this pH
Carbon dioxide can change into carbonic acid, and carbonic acid energy envelope is removed well.
Add alkali in the water inlet of first-stage reverse osmosis device 113, be easiest to produce precipitation of calcium carbonate in pH8.2 or so.
Above is specific embodiment of the present utility model, it is noted that for those skilled in the art
For, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
It is considered as protection domain of the present utility model.
