Description
Technical field
The present invention relates to a kind of product water device, especially relate to a kind of novel reverse osmosis sub-prime and produce water device.
Background technology
In existing reverse osmosis design, the product water of 1 grade of reverse osmosis is the system or the water tank that enter next stage after merging together, if needing to enter next stage system to do further process, it is necessary to processed by all product water of reverse osmosis.
The defect of prior art is now described with such as a certain case history, and in new technology illustrates, introduces the advantage of new technology for this case history.
Certain reverse osmosis system influent quality (water source is tap water, and ultrafiltration is as the pre-treatment of reverse osmosis):
Table one influent quality
This engineering produces water water quality requirement; Specific conductivity��10 �� S/cm
