physiochemical processes may occur. This technique may be reused to recover water or Treated Red water [2].
determine how well okra seed and chicken feathers worked as adsorbents in a SAT system to clean wastewater from slaughterhouses. The goal of the study was to evaluate the removal of contaminants from wastewater, including TSS, COD, BOD, nitrate (NO3-N), phosphate (PO4), iron, and nickel. The findings suggested that okra seeds and chicken feathers could both function as effective and environmentally benign adsorbents for wastewater treatment. In a column of silty soils, the research investigated changing the adsorbent locations at different percentages (20%, 40%, 60%, and 80%). When silty soil was combined with okra seed powder and applied in the SAT system at a position 60 percent from the bottom of the column, the effectiveness of silt removal increased. The advancement of sustainable pollution reduction is aided by this study
Most wastes that are created, either beneficial to humanity or detrimental. The most of garbage, particularly solid waste, is conveyed to Runoff from the outside, however much runs into the soil, transports water to streams and lakes. Human activities like raising livestock and preparing meat detrimental effects on the land and waters natural makeup in numerous areas of the universe. Such soils, natural water supplies to the surroundings become contaminated as a result.[3] Typically, meat processing takes place in a specialized setting called an abattoir or slaughterhouse. Wherever animals are murdered for their flesh, it takes places in an abattoir. An abattoir is a place where the goods intended for people to consume processed, preserved, and slaughtered in a hygienic manner [7].
Key Words: Abattoir Wastewater, Soil Aquifer Treatment System, Okra Seeds, Chicken Feathers, Silty soil.
2.MATERIALS AND METHODOLOGY
1. INTRODUCTION
2.1 Collection of Soil
Water is the most precious resource on the planet. All living things, including people and plants, depend on water for their survival. Due to the increasing population, urbanisation, industrialization, and modern agricultural practises that are leading to increased contamination of various water resources, people are today facing a water crisis. The amount of water covering the surface of the globe is over 70.9%, with seas accounting for 97% of that total, polar ice caps for 2.4%, and other local surface water bodies, such as lakes and streams, for 0.60%. The treatment of wastewater by land has been made permissible as an alternative to conventional wastewater treatment methods in order to address these problems. Although the soil was able to purify wastewater by adsorption, filtration, chemical reactions, and biological processes [1]. The usage of water for feeding (storm rainwater or leftover water from the treatment plant output) during soil passage is now in better condition thanks to the controlled aquifer recharge method, also known as SAT, as well as soil section research. This method of wastewater recovery is both practical and aesthetically pleasing a system. The aquifer and soil serve as natural filters. The SAT method may eliminate solids that have suspended pathogens, viruses, and other microorganisms. Percolation causes filtration, and after water gets inside the aquifer, mixing and maybe other

2.3 Adsorbents Preparation Okra seeds are being purchased from the nearly full market. Collected seeds are occasionally rinsed with fresh water to eliminate pollutants and debris. The cleaned seeds are left to naturally dry in the sun for 24 hours. The large seed particles are then eliminated by sifting the powder through a mesh size of 600 microns after such dry seeds are ground into a fine powder using a pestle and mortar. Combine 10g of powder that has been sieved with 1000 ml of distilled water to create a 100-ml suspension. Using a fresh magnetic stirrer, thoroughly mix the suspension and let it sit for 5 minutes to extract the component. The solution is suspended for 15 minutes, filtered to remove any impurities, and then allowed to dry for 6 to 8 hours [4,8]. Chicken Feathers was collected from khan chicken centre in Hosadurga. Wash with fresh water and detergent, then air dry outside. Blend it thoroughly when it has dried. It should
