Wastewater containing titanium pigment was treated by microfiltration membrane, Nanometer titanium can be purified and concentrated by use of microfiltration. Operational conditions were optimized and the model was built. Finally, the amount of wash water was reduced. Based on the above research, the whole set equipment was designed, which can meet the needs in a titanium industry with a capability of 500 ton per year. Backflush and automatic control were used in the equipment, which has been steadily run two years, has been widely adopted in titanium industry. The technology has been widely adopted in titanium industry.In the recent years, whole set equipment of ceramic membrane was increasingly used in the recovery of desired production from fermentation broth in China. A new membrane process integrated with pretreatment of flocculation or coagulation was exploited to recover Inosine. ZrO2 ceramic membrane was used in the work, and the average permeation flux could reach 150L/m2.h under pH value of 3, transmembrane pressure 0.1MPa, CFV 3m/s, and temperature higher than 70C. The recovery ratio of inosine is higher than traditional recovery method, although inosine degraded under acidic and high temperature condition.
