Zhenjiang Environmental Protection Electroplating Park is the only professional electroplating zone in Zhenjiang. It treats 10,000 tons of electroplating wastewater for Zhenjiang every day, and cooperates with the Environmental Protection Bureau to implement 24-hour online monitoring.

In this Zhenjiang Environmental Protection Electroplating Park project, the pH meter of Supmea was successfully used in the treatment of waste gas spray tower. By monitoring the pH and ORP values on the lye circulation device, it can automatically control the online dosing and measure the content of sodium hydroxide and sodium hypochlorite in the absorption waste liquid. The alarm value setting function of the American pH meter provides the possibility to control the peristaltic pump to feed and ensure that the exhaust gas spray effect reaches the expected effect.
