- Abstract
To evaluate the effect of the organic chlorination in the uniformity of water distribution and in the outflow of a tubedripper with 2,2 L h-1, had been tested four levels of concentrations of dicloroisocianurato of sodium (N1 = 0, N2 = 15, N3 = 30 e N4 = 45 mg L-1 of free chlorine). The evaluations had been carried through in the beginning of the experiment and to each 100 hours of functioning of the system, totalizing 8 evaluations. In the calculation of the uniformity of water application had been used the coefficients of uniformity of Christiansen (CUC), of distribution (CUD) and emission (Us). Also the study of the discharge and the coefficient of variation of the discharge (CVq). It was verified that in the level N1, reductions of 23; 30.2 and 8.35%, for the CUC, CUD and US, respectively. The discharge presented a 6.13% reduction, reflecting in an increase of the CVq. The treatment with dicloro was efficient to prevent against clogging for all the used concentrations and the system was classified with excellent uniformity in practically all the evaluations.
