Abstract - Wastewater is primarily created by manmade
past few decades. A sustainable water management strategy necessitates that decision-makers view treated wastewater as a valuable resource rather than a waste product that needs to be expensively disposed of, which increases the focus on greywater utilisation. The water should be recycled or cleaned before being released to natural water sources like rivers or lakes or in open land as groundwater recharge due to the rising demand for groundwater in metropolitan areas and cities. Due to this, the home wastewater has undergone little treatment that is more or less successful and can be utilised for a variety of tasks, including
and natural processes. Following treatment, sewage may either be dumped into a body of water, such as a lake, stream, river, estuary, or ocean, or onto land. (Gulhane et al., 2014).The present work is intended to study the application of the comparative study between the Areca husk fibre and Agava sisalana(sisal fibre) as a fixed bed for treating domestic wastewater for different parameters such as turbidity, chloride, TSS, TDS and BOD. Column study was conducted. Sample was collected at 15, 30, 45, 60, 75 and 90 minutes at different depth 10, 20, 30, 40 and 45cm in different flow rate 10, 20, 30 and 40ml/min. The maximum removal efficiency was observed at a flow rate of 10ml/min and at an optimum time of 60 minutes at a bed depth of 40cm. And in the comparative study, Sisal fiber was observed to have maximum efficiency with removal efficiency of turbidity, chloride, TSS, TDS and BOD as 79.31%, 75.86%, 63.33%, 76.67% and 75% respectively. This work shows enhanced domestic wastewater treatment ability which is economically feasible and readily available.
Biobased fibres or fibres with vegetable and animal origins are examples of natural fibres. This definition covers all naturally occurring cellulosic fibres (such as cotton, jute, sisal, coir, flax, hemp, abaca, and ramie) as well as fibres made of protein, including wool and silk. Asbestos and other naturally occurring mineral fibres that are not bio-based are not included in this list (Lotfi et al., 2019).One such type of treatment procedure used is the weakening of residential wastewater utilising two different bed materials as filter media: Agava sisalana and Areca husk fibre. Due to intrinsic benefits over suspended growth systems, the use of fixed films for wastewater treatment is being investigated more frequently. The goal of the current effort is to examine how the Areca fibre and Agava sisalana as a fixed bed for treating domestic wastewater to know the comparative removal efficiency of BOD, chloride, turbidity, TDS, TSS and analysis of pH and compared with WHO standards.

1.INTRODUCTION The primary source is thought to be water. The water cycle on earth involves the constant processes of evaporation, transpiration, condensation, precipitation, and runoff, with the goal of eventually reaching the sea. Wastewater is the liquid waste that is disposed of after use in home settings, commercial settings, industries, and agriculture. In order to establish a hygienic environment, wastewater obtained from various sources needs to be handled very well. If adequate plans are not made for the collection, treatment, and disposal of all municipal waste, it will continue to build up and create an unfavourable situation where buildings and roads will be damaged due to wastewater buildup in the foundations, endangering the safety of the structures. In general, the main goal of wastewater treatment is to enable human and industry. (Gulhane et al., 2014).
2.MATERIALS AND METHODOLOGY Sisal and areca husk fibre were the two natural fibres used in this investigation. The mesocarp tissue or husk of the areca fruit is where the versatile natural fibre known as areca husk fibre is found. Areca appears to be the most promising natural fibre due to its low cost, wide availability, and high promise as a perennial crop. The botanical name for sisal fibre is agave sisalana. Although commonly cultivated in other nations, this kind of agave is endemic to southern Mexico. Rope and twine are made from sisal fibre, which is also used to make paper, textiles, footwear, headgear, bags, and carpets(Vijayalakshmi et al., 2019).
