Duraflow’s Tubular Membrane Application
Bulletin “Printed Circuits”

This bulletin describes the use of Duraflow Tubular Membranes for treating various sources of heavy metal bearing or high COD wastewaters generated during the manufacturing of printed circuits. The bulletin documents the challenges facing the electronics manufacturing industries that use heavy metals and provides a list of targeted contaminants that have been treated and separated with the Durafow Tubular Membrane product.

Since every circuit board manufacturing facility that uses copper, tin, gold, lead and nickel has different manufacturing processes, Duraflow has developed a standard procedure for approaching each customer location. This procedure uses waste compatibility segregation, process development to meet the customer's objectives, membrane microfiltration total system engineering design, and detailed analysis of the possibility for recycling this treated Duraflow filtrate.
