On the basis of theory analysis, the average transmitted light intensity ( correspond to dc value ) was determined as characteristic parameter of raw water using photoelectric method for monitoring the fluctuation of transmitted light and photometric dispersion analyzer ( pda ). the dc value was closely related to both particle concentration and surface area of sand clay simultaneously. the experimental results shows that there is an exponential function relation between dc and surface area of sand clay in unit volume water ( sp ) : dc = asbp in which a and b are empirical coefficients. then the formula of macromolecule flocculant dosage is found to be d = f ( dc ) = e ( dc ) f in which e and / are empirical coefficients and the average correlation coefficient equal to 0. 981. so the model of automatical control system of water treatment plant was established using the formula
