Performance Evaluation of Hybrid Coagulation/Nanofiltration Process for AT-POME Treatment

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...

Chitosan/Polyethersulfone Composite Nanofiltration Membrane for Industrial Wastewater Treatment

Chitosan/polyethersulfone (CS/PES) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. The Substrate membrane was prepared by phase inversion technique using polyethersulfone (PES) and dimethylacetamide (DMAc) as solvent with and without the addition of polyvinylpyrrolidone (PVP) as pore-forming agent. The effects of the composition of the c...

Nanofiltration and Reverse Osmosis Process for the Treatment of Distillery Spent Wash

Thin-film composite nano-filtration (NF) and reverse osmosis (RO) membranes based NF followed by ROpilot plant at a feed pressure of 20 atm.and flow rate of 10 L/min. was used to remove colour, total dissolved solid (TDS) and chemical oxygen demand (COD) of distillery spent wash. NF was found to be effective for high rejection of TDS, colour and COD by 85%, 99% and 95%, respectively. Furthermor...
