Investigations on the Cleaning Agent in A RO Hollow Fine-Fiber Module
This work was carried out to the make-up water for the boilers at the Tabriz power plant in Iran is treated by a reverse osmosis (RO) process.In this work foulants, cleaning agent on the membrane surface were investigated.The results for EDTA and oxalic acid for removal of foulant on the hollow fine-fiber surface, indicated that SDS and Goli cleaner are not suitable. It was concluded that EDTA and oxalic acid are more effective.
