Abstract

On-line turbidity detecting is widely used in water purifying control and waste water processing. In this paper, scattering turbidity measurement is analyzed in terms of Mie scattering theory. An on-line turbidity measurement system using surface scattering technique was established. The receiving optics was elaborately designed to reduce the influence of sample's watermark change. The turbidity accuracy of smaller than +/- 5 percent was obtained over the range from 0 to 1000 NTU.
