Summary
In the production process of PCB industry,there exists two problems:1.Large water consumption;2.a variety of pollutants whose constituents are complex And its major pollutants include acid,alkali,Cu,SS and COD,etc.

                                                 
Characteristics
1.  Considerable economic benefits.The equipment cost can be gain back within 3 years.
2.  The recovery rate can be up to 75%—95%.
3. Stable recovering water quality which is lower than 30us/cm.
4. The wastewater recovering cost can be reduced to less than $0.2/m3
5. The equipment can guarantee the continuous production during the period of being limiting water or lacking water.
6.  There is no need to increase the quantity of equipments if the users want to expand the scale of production.
7.  Automatical and continuous system is appropriate for wastewater with large flow.
8.  The recovering water can be used in pure water system or recycle to production lines directly.
9  Low trouble and convenient maintenance.
10.  Low operation cost
