- Abstract
The activated sludge process is a biological treatment consisting basically of agitation and aeration of a waste water mixture and a selected microorganisms sludge. The oxidation of organic matter was determined with several tests such as BOD5 (Biochemical Oxygen Demand), TSS (Total Sedimented Solids), SS (Sediment Solids), TDS (Total Dissolved Solids), FVS (fixed and volatile solids) and finally a measurement of treated water turbidity. The results obtained for the reduction of the organic load during the first two days of treatment (samples 1, 2 and 3) are visible in each of the organic loading tests; during the last two days according to the samples 4 and 5 the solids showed an increase in organic load. The related organoleptic properties such as color showed a notable decrease. As for the tests performed at pH show a change, samples 1, 2 and 3 approaching a range where they are neutral and the last two samples (4 and 5) the pH has an elevation until it becomes alkaline. The efficiency of the method used for the treatment of residual water during the first days reduced the organic load with a variation of TS and TSS of 760, 569 ppm respectively. This is a viable alternative since this is a low cost method with short term results because organoleptic properties such as odor and color were lost during the first day of treatment.
