Study The Different Parameters of Sewage Treatment With UASB & SBR Technologies

Abstract

Every community produces both liquid and solid wastes and air emissions. The liquid waste-wastewater-is essentially the water supply of the community after it has been used in a variety of applications. From the standpoint of sources of generation, wastewater may be defined as a combination of the liquid or water-carried wastes removed from residences, institutions, commercial and industrial establishments, together with such groundwater, surfacewater and stromwater as may be present. This waste water through sewer comes to the sewage treatment plant so that parameters are reduced and treated wastewater be disposed into water or land. For treating the sewage UASB(UP FLOW ANAEROBIC SLUDGE BLANKET) and SBR(SEQUENCING BATCH REACTOR) technologies are mostly used. All the parameters of these samples were analyzed using standard methods prescribed in "Standard methods for examination of water and wastewater". It was observed that pH & temperature values at outlet by both the processes are almost same. Reading were taking on two consecutive days and value of Biochemical Oxygen Demand by UASB process was 32, 32mg/l and by SBR process was 11, 16mg/l. Chemical oxygen Demand by UASB process was 112, 96mg/l and by SBR process was 32, 34mg/l. Total Suspended Solids by UASB process was 58, 44mg/l and by SBR process was 10, 12mg/l. Both the processes were used for treating the wastewater and the SBR process showed better results as comparative to UASB. Objective oF Study: To study the degree of correction occurring on the sewage after treating with UASB and SBR technologies at STP, Village Balloke, LUDHIANA In this study attempt has been made to study the difference between two technologies after treatment process is done. Process followed is as under (1)Collection of the sample (2)Determination of the physical & chemical characteristics.
