An Experimental Study of Sequencing Batch Reactors (Sbrs) for Wastewater Treatment Under Local Conditions For Use in Irrigation

Abstract

The research is summarized in conducting a series of experiments on a laboratory model of a sequencing batch reactor (SBR) to verify its effectiveness in treating wastewater and its potential use for irrigation purposes.The research discusses the characteristics of wastewater and the risks of contamination,in addition to presenting the known methods of treatment. The research also includes a detailed presentation of sequencing batch reactors (SBRs), their design mechanism, and the calculation of the design parameters of the reactor under study based on the characteristics of the wastewater used in all stages of the test.The research methodology included the operation and steps followed to test the proposed reactor model under prevailing laboratory conditions.Samples were taken from the reactor over six consecutive days, and then the basic parameters necessary for evaluation were measured, namely: TSS, BOD5, nitrate, nitrite and phosphate. We have presented the results in special tables that allowed us to evaluate the effectiveness of the proposed method for wastewater treatment.The test results at the approved operating cycle times showed high effectiveness in removing BOD and TSS, while this effectiveness was lower in removing nitrate and phosphorus due to their already low values in the water undergoing treatment.Finally, an analytical reading of the results presented the conclusions, which allowed us to reach recommendations that we consider important to take into account in subsequent research in this field.
