The application in Electroplate and hull painting industry
In Electroplate and hull painting industry, in order to increase the accessory smooth finish of a surface, luminance, adhesive force, it has to use the pure water under 15uS/cm-5uS/cm of conductivity. In addition the plating needs to wash with pure water under 10uS/cm of conductivity too. And also ultra filtration and reverse osmosis can be used for recycling the valuable metal ion rinsed in the liquid, while pure water permeated can returns to wash planting again.
The closed production line and less sewerage
equipment:
The closed production line and less sewerage equipment includes pure water
treatment for washing accessory and sewerage equipment for recycling the
valuable metal ion and washed water.
