Wastewater from Semiconductor Manufacturing Solution

The wastewater treatment system for electroplating and semiconductor industries is used for finishing and metal plating industries. The system completely removes heavy metal residues, oil, and suspended solids before discharging into the environment. The treated wastewater complies with the national technical regulation QCVN 40:2011/BTNMT on industrial wastewater.

The electroplating industry generates wastewater in various processes such as washing, rinsing, plant cleaning, equipment cooling, etc. The most notable pollutants in electroplating wastewater are low pH and heavy metals - initial materials used include chromium, nickel, copper, zinc, etc., each with different concentrations. Metal ions can cause serious harm to humans, animals, plants, and the environment. Therefore, the most important goal is to eliminate these substances.
