Analysis of Physico Chemical Characteristics of Bioadsorbent Treated Paper Mill Effluent

The paper mill effluent containing heavy metals that are toxic to plants, reduces the plant yield and even the soil fertility, although these toxic substances could be removed by plants and dried plant materials. Agricultural waste remediation is an effective low cost biotechnological tool for cleaning polluted environment. Research work focused on the dye from the paper mill effluent was treated with dried powdered Datura, Calotropis, Abutilon and Typha. After the treatment, the physico-chemical characters were studied and compared with untreated effluent parameters. It showed drastic changes in physico-chemical characteristics over the untreated effluent and also the heavy metals were found to be absorbed from the paper mill effluent by dried weed plants. Dried weed plants are low cost bio adsorbent for removing heavy metals from paper mill effluent.
