Pollution is direct or indirect change of any component of the biosphere that is harmful to the living components and in particular undesirable for man. It adversely affects the industrial progress, cultural and natural environment. Water pollution refers to the contamination of water bodies such as rivers, oceans, lakes, and groundwater caused by human activities. This can be harmful to plants and organisms which live in these water bodies. Different type of needle punched nonwovens of 100% bamboo charcoal polyester fibre (BCP), 100% polyester fiber and BCP: Cotton blends with different GSM were selected. Domestic untreated sewage water, treated sewage water and tap water were filtered using the developed nonwovens at standard speed and time. The DO, BOD, COD, and TDS were evaluated using standard procedure. The experimental results reported that the BCP nonwovens showed greater reduction of COD, BOD and TDS when the thickness was higher. The dissolved oxygen level has increased after filtration indicating that filtered water provides suitable survival condition to the aquatic life. On the other hand BCP: Cotton blend and polyester fibre showed less reduction than 100% BCP fabric. The presence of the bamboo charcoal nanoparticles in nonwovens influenced the waste water filtration. This may reduce the chemical usage of the effluent treatment.
