2. Evaluating the Potential of Biodiesel Production through Microalgae Farming in Photobioreactor and High Rate Ponds from Wastewater Treatment
In the last decade, the research works on microbial as a potential source of lipid for biodiesel production have been growing. In this work, the potential of a sludge from high-rate lagoons in urban sewage treatment, composed mainly by Chlorella sp., as oil source for biodiesel production, was studied. The potential of Chlorella sp. growth in photobioreactor

4. Characterization of Lipase from Bacillus subtilisI-4 and Its Potential Use in Oil Contaminated Wastewater
ABSTRACTA lipase producing bacterium was isolated from oil contaminated effluents of various industries from Sheikhupura Road, Pakistan, and, on the basis of biochemical and 16S rRNA ribotyping, was identified asBacillus subtilis. The optimum temperature and pH for the growth of the culture were 37ºC and 7.0, respectively.B. subtilis I-4 had a lag phase of

5. Industrial wastewater as raw material for exopolysaccharide production by Rhizobium leguminosarum
The objective of this study was to evaluate the exopolysaccharide (EPS) production by Rhizobium leguminosarum cultivated in wastewater generated by oil companies (WWOC1 and WWOC2) and fish processing industry (WWFP). The results obtained in Erlenmeyer flasks indicated that the rhizobial strain grew well in industrial wastewater. Generally, wastewater composi

8. Characterization of produced water in the oil industry for disposal and optimization of oil water separation. / Caracterização de água produzida na indústria de petróleo para fins de descarte e otimização do processo de separação óleo/água
The oil industry has several segments that can impact the environment. Among these, produced water which has been highlight in the environmental problem because of the great volume generated and its toxic composition. Those waters are the major source of waste in the oil industry. The composition of the produced water is strongly dependent on the production

11. BORON REMOVAL FROM OIL PRODUCTION WASTEWATER AND EFFLUENTS BY ADSORPTION / REMOÇÃO DE BORO DE ÁGUAS E EFLUENTES DE PETRÓLEO POR ADSORÇÃO
The presence of boron in waters has increased continually and in parallel to the industrial development. And also, the harmful effects to the organisms and living creatures has increased as well, especially on plants, where the gap between the deficiency and the toxicity is very short. In the present work it was investigated the effects of different operatin
