Investigation of membrane fouling in surface treatment plant using reverse osmosis process

The surface treatment industry is likely to bring pollution, nuisances and hazards that require a rigorous treatment of the effluent. The membrane technologies Wake great interest in the treatment of industrial waters, it depends on membrane type, the effluent to be treated and the operating conditions, the membranes may lose its characteristics over time. Clogging or fouling is the most important problem related to the use of the membranes, which results in an allows flow and decrease in an increase in passage of salts and of the differential pressure. In addition to the deterioration of the reverse osmosis, fouling can damage irreversibly the membranes and prevent effective cleaning it. For a better recovery of the membranes, it is necessary to have all information related to the deposited material is for this reason that the realization of an autopsy is becoming a necessity in order to undertake a comprehensive review of the filing of the membrane and the integrity of all components of the same. Definitely, the autopsy of the membrane allows to study the reasons clogging detail that can be used to develop the best cleaning conditions and manner of the avoided in the future. The objective of this work is to conduct a study deepens on the material deposited on the active layer of the membrane previously used in the treatment of effluents from a surface treatment plant with the completion of an autops
