Cả hai nước uống và nước quá trình chất lượng cao có thể được khử trùng bằng công nghệ tia cực tím (UV). Điều tương tự cũng giữ cho nước thải được xử lý. • hướng dẫn chính xác áp dụng cho việc thiết kế các thiết bị. Rất thường xuyên các thông tin có sẵn cho khách hàng vẫn còn một chút kinh nghiệm và chỉ đơn thuần là thương mại. • Bằng cách tích hợp kiến thức và kinh nghiệm hiện tại, nó có thể tích hợp các quy tắc thích hợp cho thiết kế và phương pháp. | 6 General Conclusions Both drinking water and process water of high quality can be disinfected by available ultraviolet UV technologies. The same holds for treated wastewaters. Precise guidelines apply to the design of equipment. Very often the information made available to the client remains somewhat empirical and merely commercial. By integrating present knowledge and experience it is possible now to integrate adequate rules for design and methods for evaluation of performance. Depending on the case tentative general rules are indicated in this text Sections and . The choice of a given technology and the performance of a given option of the UV lamps are determinants depending on the expected result. Tailoring to measure is possible at present see Chapter 2 . The selection of the lamp is a determining issue that depends on any particular application. Constant progress is being made in the field see Chapters 2 and 3 . Appropriate design of reactors is an element for the success of the method to be evaluated in each case see Chapters 3 and 5 . In all instances essential data on the general quality of the water remain necessary such as total suspended solids transmittance of UV light concentration of dissolved oxygen turbidity iron content and general ionic balance. Fundamental principles of the application are at present thoroughly grounded and explained in this text. Cost parameters may be very case dependent. These are not commented on in this contribution and should be evaluated for each specific application. 2002 by CRC Press LLC Glossary absorption coefficient. See Beer-Lambert law. Beer-Lambert law. Quantifies the absorption of a monochromatic wavelength by an homogeneous substance relating the incident radiant intensity Io to the transmitted intensity I by I Io X 10-ACd where A is the absorption coefficient C the concentration of the absorbing species and d the optical path length usually in centimeters . The units for A are either in liters
