Research paper thumbnail of Reclamation of dye wastewater using a flat sheet nanofiltration membrane: Study of permeate flux and quality

This study presents treatment of dye containing wastewater in a nanofiltration pilot plant using ... more This study presents treatment of dye containing wastewater in a nanofiltration pilot plant using hydrophilized polyamide membrane of flat sheet module. Permeate flux (PF) decreased with time of operation due to concentration polarization. Effect of trans-membrane pressure (TMP) showed a quasi-linear increase in flux with increasing pressure. PF (1.44 × 10-6 m 3 /m 2 .s) at 5 kg/cm 2 was enhanced as PF (1.62 × 10-6 m 3 /m 2 .s) at 10 kg/cm 2. Flux increased considerably with increase in dilution of wastewater. Maximum PFs obtained with 5 fold and 10 fold dilutions were 3.95 × 10-6 and 7.06 × 10-6 m 3 /m 2 .s respectively. Substantial removal of colour (98.3%) was achieved with a marked reduction in COD (89%) and TDS (77.2%).

Research paper thumbnail of Catalytic Rates & Pressure Drop in PFR Reactors: HYSYS 3.0 Reactor Types in HYSYS

Objectives: 1. In this session you will learn how to convert a first order catalytic reaction rat... more Objectives: 1. In this session you will learn how to convert a first order catalytic reaction rate for use in the PFR. 2. In addition you will use the Ergun Equation to simulate the pressure drop within a PFR. (The reverse reaction or equilibrium will be ignored in this tutorial.)
