Printed Circuit Board manufacturing and populating are processes which require attention to detail, in both pure water and wastewater treatment. Evoqua supplies services and equipment to supply high purity deionized (DI) water for rinse water and process wash water makeup.
Spent process and wash waters can contain metals waste (Ni, Cu, Ag, Au, Pb, Sn) as well as other unwanted contaminants (pH, TOC, TDS) which must be treated prior to discharge or recycle. Evoqua’s wastewater ion exchange systems and capital equipment are used to remove the hazardous components, allowing the treated rinse water to either be recycled back to the washers or discharged to the POTW. The contaminant-laden ion exchange media is shipped back to Evoqua’s owned and operated RCRA treatment facility for compliant processing which epitomizes the “cradle to grave” waste treatment approach.
