wastewater is a serious problem when it is discharged without the proper treatment. In this work, wastewater generated by textile industry was treated coupling a homogenization-decantation treatment with polyvinylidene difluoride (PVDF) ultrafiltration membranes. Initially, the wastewater was aerated in a homogenization-decantation tank where 17%

Members of the genus Spirochaeta are free-living obligate or facultative anaerobes. They are probably the spirochetes occasionally seen in activated sludge ,wastewater treatment, systems (Figure 10.29), where they are indicative of anaerobic conditions. In some species the length may exceed 200 mm. Figure 10.29 Spirochetes in activated sludge.

Abstract Decoloration of acidic ,scarlet, GR by pyrolusite is studied in this paper. The effects of pH in solution, dosage and granularity of pyrolusite, reaction temperature, and vibration speed on decoloration efficiency are discussed. According to experiment results, the decoloration efficiency may exceed 95% for 40 mg/L GR solution by pyrolusite. pH is most important among all factors which ...
