N2 - Industrial water saving is the focus of the world's attention. A new theoretical algorithm is explored in this paper: firstly, based on the basic formula of mass and concentration, the theoretical minimum water flowrate is calculated by drawing a concentration-interval diagram and concentration-composite curve. Secondly, based on the proportional mass-transfer assumption, and the basic formula of mass and concentration, the preliminary design for the water-using network of a multiple-contaminant system, is produced using a concentration-interval design method. Thirdly, the water-using network is optimized, and the minimum number of water-using units is calculated by the method of loop breaking. Using this theoretical algorithm, automobile factory A, of Hei Long Jiang province in China, was selected as the test site. By the application of the scheme, the minimum water flowrate can be achieved, saving as much as 19 percent of the original freshwater. The research methods, procedures and results of calculations, are all provided in this paper. Project (HIT. MD 2002.29) supported by the Scientific Research Foundation of Harbin Institute of Technology.
