Tianjin Auto Parts Product Quality Supervision and Inspection Center was formally established
Recently, Tianjin Auto Parts Product Quality Supervision and Inspection Center was formally established. The center covers an area of ​​2,500 square meters, and the first phase invests 20 million yuan. The existing environmental laboratories, functional laboratories and material laboratories can undertake import and export. Motor vehicle parts product inspection.
According to reports, the center can undertake a variety of automotive parts quality inspection tasks and undertake the task of quality inspection testing of parts and components commissioned by government agencies, intermediary organizations, and business units at all levels. The establishment of the center will become the first large-scale auto parts inspection center with wide inspection scope and strong detection capability in the Bohai Rim region, and it will help improve the overall level of Tianjin's auto industry and increase the technical added value of parts and components.
Secondary Water Supply Disinfection
Ultrasound (US) and chlorine dioxide (ClO(2)) were combined sequentially in an aim to improve Wastewater Disinfection. Results demonstrated that the combined effect of US and ClO(2) on Escherichia coli (E. coli) and total coliform (TC) inactivation in raw wastewater was synergistic involving high removal of bacteria from the solution. A sequential combination of US (150 or 300 W/L) and ClO(2) (2 mg/L) provided about 3.2-3.5 log reduction in the number E. coli and TC in raw wastewater, while the sum of log reductions by the individual treatments were 1.4-1.9. However, the measured inactivation rate with the combination of ultrasound and ClO(2) in synthetic wastewater or secondary effluent was the same as the sum of the log inactivations with individual treatments. The enhancement attained by combined US and ClO(2) disinfection methods was attributed to the presence of high concentration of particles in raw wastewater and their break up under shock sound waves.
