Graphene Oxide (GO)-Blended Polysulfone (PSf) Ultrafiltration Membranes for Lead Ion Rejection

Autor: Harish Ravishankar, Jens Christy, Veeriah Jegatheesan

Publikováno v: Membranes, Vol 8, Iss 3, p 77 (2018)

Graphene oxide (GO) has been widely reported and used for treatment of heavy metals from different waste streams. Although their use as additives for membranes has greatly enhanced membrane properties, there is still a bottleneck in obtaining membran

Performance evaluation of A2O MBR system with graphene oxide (GO) blended polysulfone (PSf) composite membrane for treatment of high strength synthetic wastewater containing lead

Autor: Veeriah Jegatheesan, Shamima Moazzem, Harish Ravishankar

Publikováno v: Chemosphere. 234:148-161

High strength synthetic wastewater containing 5 mg L−1 of lead was studied for treatment using an A2O MBR system. The system showed 99% removal of ammonia and COD, a maximum removal of 52% of total phosphorus and an average minimum removal of 72% o
