Optimization of experimental parameters in the treatment of textile effluents charged by colorant blueTelonthe using the experimental design method

In the present paper, a systematic study of the influence of experimental parameters and operating conditions on the effectiveness of the adsorption process using olive active as adsorbent. The influence of the parametersis studied at two levels, fractional factorial designs and a Doehlert uniform shell design to determine the influence of the adsorption conditions. The analysis of the experimental responses (mass adsorbent (Natural Resin)and Temperature and Time and pH, respectively) shows that the parameters which have the greatest influence change depending on the response. The results concerning the theoretical parameters, allowed us to give better treatment by adsorption (Natural Resin (NR), blue Telon (BT)) in optimal conditions, namely: the temperature in the range (80 °C), mass Natural Resin order (50mg), the agitation of the order (1000Torr/min) and the pH of the order (10
