| Abstract: | Aiming at raw water quality and requirements of environmental protection,reverse osmosis(RO)technique was adopted for wastewater treatment.In this paper,process flow and main equipment are introduced,the applied experience and effect of wastewater treatment by reverse osmosis technique for steel factory are expounded.Through the observation on the variation of electric conductivity,water yield,operating pressure,the genesis of membrane fouling is analyzed and cleaning program is put forward;issues of operational management for reverse osmosis system are discussed.It is shown that the acid-alkali-acid cleaning program is efficient for controlling RO membrane fouling. |
| Keywords: | reverse osmosis wastewater reuse membrane fouling cleaning operational management |
