| BACKGROUND The press juices resulting from a compacting operation on fish by-products were subjected to a depuration treatment in order to reduce the high COD (120 g O2 L–1). The process included an initial de-particulation step by means of two metallic filter cartridges of 465 µm and 250 µm, followed by concentration with a 200 nm ultrafiltration ceramic membrane. The polishing efficiency of each unit was assessed in terms of COD and protein removal. RESULTS Dead-end metallic filtration of the press waters reduced their suspended matter content by 28%, but achieved only 5.6% decrease in chemical oxygen demand (COD), which suggested further processing by membrane ultrafiltration. The de-particulated stream was then subjected to ultrafiltration for 8 h in... |
