Simulation of Colored Waste Water Treatment Using Photo Fenton in Continuous System Waste water from coffee processing was treated by the Photo Fenton method. Experiments were carried out in a 2 liter batch reactor equipped with ultraviolet lamp for 4 hours. The synthetic waste water was made by dissolving 300 mg instant coffee in 1 liter water. Reagents used are 700 ppm H2O2 prepared from 30 % H2O2, and 15 ppm FeSO4.7H2O. The experiment was carried out at pH= 3. Prior to treatment, the color of the waste water was brownish yellow.

Hence selectivity is the real problem.

The BARD project was a continuation of a previous BARD funded research project. It was aimed at characterization of the 12kDa immunodominant protein and subsequently the cloning and expression of the gene in E. coli. Additional immunodominant proteins were sought among genomic B. abortus expression library clones using T-lymphocyte proliferation assay as a screening method. The 12kDa protein was identified as the L7/L12 ribosomal protein demonstrating in the first time the role a structural protein may play in the development of the host's immunity against the organism. The gene was cloned fro
