Abstract
The purpose of this research was to compare the RO membrane performance such as permeate flow rate, flux, recovery ratio according to the membrane CIP(Clean-In-Place) methods(One-way CIP and two-way CIP). The seawater used in this research was sampled at a depth of 3∼5 m in the sea located in B City. The average water quality of seawater was found to be turbidity of 1.28 NTU, TDS 30,335 ㎎/L, hardness 3,330 ㎎/L as CaCO<sub>3</sub>, and SO<sub>4</sub><sup>2-</sup> 1,890 ㎎/L. The flux of the new RO membrane, fouled RO membrane, one-way CIP membrane and two-way CIP membrane were 97.3 L/㎡·hr, 66.5 L/㎡·hr (recovery ratio : 68.0 %), and 81.1 L/㎡·hr (recovery ratio : 83.3 %) and 94.1 L/㎡·hr (recovery ratio : 96.7 %), respectively. It was found that the two-way CIP membrane washing method showed higher washing efficiency than the one-way CIP membrane washing method.
