Abstract - Water pollution arises from the
solvent, have the ability to dissolve a large range of chemicals. This property enables vital biological processes, from nutrient transport in organisms to the erosion of rock formations over millions of years.
discharge of domestic waste, which comprises residential, industrial, commercial, and agricultural wastewater. Traditional water treatment techniques involving aerobic/anaerobic processes may exacerbate the emission of greenhouse gases. To address this issue, a microbial-based approach utilizing polyvinyl alcohol biofilm supporting media has been introduced as a viable alternative. There is a pressing need for technologies that ensure low excess sludge yield rates and highly efficient biological treatment methods for domestic sewage. The moving-bed biofilm reactor shows significant potential in meeting these requirements. This study aims to estimate the bacterial diversity in polyvinyl alcohol (PVA) gel beads and proposes a method to mitigate excess sludge yield rates while treating domestic sewage through a moving-bed biofilm reactor system employing PVA gel beads as a biomass carrier.
Water is the essence of life; its unique properties make it vital for all known forms of life. Not only does water support us by quenching our thirst, but it also plays a vital part in different biological processes, from digestion to temperature control. Furthermore, its capacity to break down a wide extend of substances makes it a great solvent, facilitating chemical reactions essential for life. Water could be a primary ingredient in cooking and food preparation. It is utilized for boiling, steaming, washing, and rehydrating dried foods. Numerous cooking processes would be impossible if there were no water. The human body is composed of around 60% water, and keeping up appropriate hydration levels is crucial for overall wellbeing. Water is fundamental for substantial functions such as circulation, absorption, absorption of nutrients, and the regulation of body temperature. Water is fundamental for the right digestion of food and the absorption of nutrients within the digestive tract. It helps break down food particles, helps within the development of nutrients over cell membranes, and encourages the disposal of waste products.
The findings of the research demonstrate the efficiency of treating domestic wastewater across various parameters, including pH levels, biological oxygen demand, chemical oxygen demand, nitrate, ammonia, phosphorus, and total suspended and dissolve solids. Consequently, the use of polyvinyl alcohol (PVA) beads in domestic wastewater treatment proves effectiveness, reducing the necessity for constructing sewage treatment plants and eliminating the need for non-recyclable materials like synthetics and plastics.
Wastewater refers to any liquid waste originated from a community generally conveyed by a sewer is called as wastewater. it consists of wastewater from kitchen, washbasin, urinals, WC, bathrooms from public and private buildings; it also includes water from industrial processes, commercial activities, and agricultural practices and stormwater runoff and has become contaminated or altered in quality as a result, rendering it unsuitable for its original purpose. Domestic wastewater refers to water contaminated by human daily consumption. Domestic wastewater is the most polluting source of natural water bodies in India. According to reports, COD, BOD, and ammoniacal-nitrogen were among the pollutants that polluted more than 25% of India’s river basin. Commonly, Domestic sewage contains a low concentration of organic pollutants, a high content of suspended solids, and numerous pathogenic bacteria and worms. If it is directly discharged into bodies of water or groundwater, it will pollute the water and cause eutrophication of lakes and river. Wastewater typically contains a variety of pollutants, including organic and

1. INTRODUCTION Water is the Substance that All living things, from small bacteria to giant blue whales need water to survive. Life as we know it would not exist if there were no water, and life exists wherever there is water. Covering about 71% of the earth's surface. Water is an odorless, tasteless, and nearly colorless chemical substance with the chemical formula H2O. A molecule is formed by bonding two hydrogen atoms with one oxygen atom. It exists in three primary states: liquid, solid (ice), and gas (water vapor), and its unique properties make it essential for various physical, chemical, and biological processes. Water is known as a universal
