Abstract

This paper discusses the effect of calcium carbonate on spiral-wound membrane performance. Experiments were carried out in a Reverse Osmosis Desalination system (2000 l/d capacity) with spiral-wound polymer composite type membrane. Atomic absorption spectroscopy was used to measure the calcium concentrations in both permeate and reject streams. The parameters chosen for this study include applied pressure and calcium carbonate concentration. Results show that the ratio of sodium hydrogen carbonate to calcium chloride in feed affects the effectiveness of the spiral wound membrane. Increases in operating pressure has a pronounced effect on the build-up of calcium ions for various ratios of sodium hydrogen carbonate to calcium chloride solutions.
