Electroplating Wastewater Treatment
Metal Hydroxide Clarification for Surface Finishing
Plate settler systems for electroplating and metal finishing wastewater — clarifying precipitated metal hydroxides after neutralization.
Electroplating Wastewater Treatment
Electroplating and metal finishing generate wastewater containing dissolved heavy metals, acids, alkalis, and complexing agents. After hydroxide precipitation, the resulting metal flocs must be efficiently separated to meet strict discharge limits.
Plate settlers clarify precipitated metal hydroxide sludge following neutralization and flocculation. The inclined plate geometry provides high solids capture in a compact footprint, producing a clear overflow suitable for discharge or polishing.
Settled metal hydroxide sludge is thickened for dewatering and disposal, while stainless steel construction withstands the aggressive chemistry of plating rinse waters.
Treatment Challenges & Solutions
Heavy Metals
Hydroxide precipitation upstream forms flocs that plate settlers clarify.
Aggressive Chemistry
SS 316L resists acidic and alkaline plating rinse waters.
Discharge Limits
High clarity supports compliance with strict metal discharge standards.
