Coagulation/flocculation of textile effluent using a natural coagulant extracted from Dillenia indica.

The aim of this study was to assess the efficiency of mucilage extracted from the fruit of Dillenia indica for enhancing coagulation in the treatment of textile effluent. The mucilage extraction was carried out in water at room temperature. The pH, concentration of coagulant FeCl.

Optimization of photocatalytic degradation of biodiesel using TiO/HO by experimental design.

This study reports on the investigation of the photodegradation of biodiesel (B100) in contact with water using TiO/HO. The TiO was characterized by X-ray diffraction analysis (XRD), pH point of zero charge (pH) and textural analysis. The results of the experiments were fitted to a quadratic polynomial model developed using response surface methodology (RSM) to optimize the parameters.

The use of a natural coagulant (Opuntia ficus-indica) in the removal for organic materials of textile effluents.

The goal of this study was to investigate the activity of the coagulant extracted from the cactus Opuntia ficus-indica (OFI) in the process of coagulation/flocculation of textile effluents. Preliminary tests of a kaolinite suspension achieved maximum turbidity removal of 95 % using an NaCl extraction solution. Optimization assays were conducted with actual effluents using the response surface methodology (RSM) based on the Box-Behnken experimental design.
