| Abstract: | A lot of washing wastewater is produced from surface grinding as well as electroplating of copper, nickel and tin during the production of printed circuit board (PCB). It is significant to recover the wastewater due to its low contamination and large amount. The effluent from chemical treatment of common washing water produced by PCB manufacturing was recovered via a combined ultrafiltration-nanofiltration (UF-NF) process. The removal of CODCr, Cu2+ and TDS (total dissolved solids) and recovery rate in diff... |
