Remediation of dyes in textile effluent by membrane based treatment techniques: A critical review

The most important industry implicated in our exposed population is the textile industry arena because of their undeniable contributions to basic human needs satisfaction and to the world economy. These industries are utilizing higher volume of water that finally results in an abundant wastewater generation; these are the major water polluting sources of ecosystem.The present paper provides a review of the management of the membrane technology towards textile effluent treatment. The concept of water reuse is also catching on quickly through membrane based techniques, including the prospect of turning textile sewage into the clarified water. We are using the microfiltration, ultrafiltration, nanofiltration and reverse osmosis.    

The optimization of experimental parameters of the synthetic polymer containment in the conditioning of solid radioactive wastes used in the purification of the circuits of TIGA Mark II reactor

In this study, we treated the conditioning of radioactive wastes by the method of management [1] using the ion exchange resin (IER) as radioactive waste [1, 2, 3]. From the values ​​obtained by experimental studies [2], we were able to optimize the conditioning process by the experiments plan approach using the NEMRODW software.The objective of this article is an in-depth theoretical study of the conditioning of radioactive wastes with the introduction of an adjuvant which is the synthesized polymer. The optimization of parameters by this software has enabled us to determine the optimal conditions for a better packaging.The influenced theoretical parameters results in the most adopted parameter to optimize the number of experiences used for the conditioning of ion exchange resins to obtain a better formulation to reduce the number of the realized tests on the one hand, and to increase the resistance to the compression of matrices in polymer on the other.

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
