8.1.2 Fluid Flow Resistance MeasurementsTo carry out the fluid flow resistance measurements, first membrane films supplanted over thenon-woven fabric were cut with area section of 4.1 cm 2 in accordance with a 10 ml filtration cell(Amicon®) dimensions (Figure – 8.1a). The experimental set-up for the measurements (Figure – 8.1b)consists of a dead-end filtration cell containing the membrane. Water is supplied to the cell underpressure from a reservoir which is in turn maintained at the pressure by compressed air inlet. Thepressure can be regulated using the attached manometer. The filtration cell consists of a small outletfrom which the permeated water is collected into a very light weight plastic recipient. The recipient itselfis kept onto a weighing balance which in turn is connected to the computer to monitor the gain in themass of recipient. The software was used to register the mass gain as function of time. The waterpermeation experiments were conducted at various pressure drops by regulating the compressed airinlet and following the water flux through encased membrane films over time. The experiments wereended once an equilibrium state was reached.Figure – 8.1: Images of a) Exploded view of Filtration cell along with membrane supported over non-woven fabric,b) Experimental set up for water permeation and translocation experiments.143
