Abstract Soil Aquifer Treatment System is one of method used for treating rural wastewater. SAT is used for treating various wastewaters. SAT is a geo-purification system which utilizes physical, chemical, biological processes during infiltration of wastewater effluent through soil strata to improve quality of water. A large section of people lives in villages and they are mainly engaged in agriculture. The scarcity of water which creates more problems in living organisms. Due to this problem treatment is adopted for reuse of water. SAT system provided maximum removal efficiencies for various parameters such as Total Suspended Solids 76.53%, for Total Dissolved Solids 84.97%, for Chemical Oxygen Demand 87.55%, for Biological Oxygen Demand 85.08%. Keywords- Soil Aquifer Treatment, Rural Wastewater, Adsorbents, Soils
I. INTRODUCTION Water is naturally occurring in nature due to water many activities are carried in the world. Water is the major source for the living and non-living organisms. Now a days peoples are facing shortage of water due to increasing in population, urbanization, industriazation, modern agriculture practice causing more contamination in various water sources. The various countries public communities faced these problems and they took decision for water resource management to meet the increasing needs of water and maintain the sustainable environment. To solve these problems the treatment of wastewater through land use has come into force as alternative technology other wastewater treatment methods, in this treatment of wastewater by land. The wastewater which is pretreated is allowed to percolate through an unsaturated aerated soil region although the soil which was purifying capacity of wastewater through operation and process such as adsorption, Filtration, chemical process and biological degradation. The wastewater is treated by soil flows in lateral direction for the considerable amount of space through an underlying aquifer (saturated Zone) where it receives more purification by means of dilution and dispersion. In this type of land treatment soil and aquifer involve in recovery process, hence this treatment process is called as soil aquifer treatment (SAT) system. Soil aquifer treatment is an economical and aesthetic wastewater recovery system. The soil and aquifer acts as a natural filter. SAT system can eliminate suspended solids, biodegrable materials, bacteria, viruses and other microorganisms. Significant reductions of phosphorous and nitrogen were reported and removal of heavy metals from wastewater is also possible with the sorption and physic-chemical stabilization. Due to shortage of water, re-use of discharged water from the sewage treatment plant can be an alternative water resource considering the huge amount of discharged water from the plant it is directly discharged to river and the sea without reuse and the cost effective and easy operation of SAT system, application of SAT to reuse wastewater can be a good way to secure water resource.
II. MATERIALS AND METHODOLOGY A. Waste Water Sample Collection Rural wastewater was collected from a gutter flowing near Lakshmipura village Davangere district, Southern part of India. Sample was collected from single point where water was not stagnant. – Collected Location-Lakshmipura village,Davangere – Collection season-Summer – Date and Time-15th march 2017 at 4:20 pm – Temperature-30̊
