Poly-vinyl alcohol (PVA) is a well-known water-soluble synthetic polymer which is widely used in textile, paper and dyeing industry. in addition to this, it is widely used as food packaging and wrapping material to keep food safe inside of the container. PVA is a biodegradable polymer, that is a major concern for the pollution level of the environment. This study provieds the possible biodegradation level under suitable conditions of susceptible amount of micro-organism that are present in the working environment. Furthermore, experimental analysis was carried out into three major phases-enrichment of biomass, acclimation procedure and PVA degradation, considering the major parameters, likely pH, mixed liquor suspended solids (MLSS), mixed liquor volatile suspended solids (MLVSS) and chemical oxygen demand (COD). In this paper, the Finley method was adopted using a UV-VIS spectrophotometer with the help of a calibration curve to measure the concentration level of PVA. Thus, this study focuses on the biodegradation level of poly-vinyl alcohol (PVA).
