Pilot scale UF and RO studies on water reuse in corrugated board industry

摘要

The coloured effluents from pulp and paper mill industry are treated anaerobically and/or aerobically by a two stage membrane system with high efficiency. Three different types of membranes (UF and Ro (BW and SW)) were used in the experiments. Surface area of each membrane was 2 m~2. The combination of ultrafiltration (UF) and reverse osmosis (RO) treatment achieve a very high removals of COD (98-99
