In the current scenario industrialization is increasing day by day. The by products are
released to air, water and soil. Certain industries like electroplating, pigments, metallurgical
process, mining, leather industries, dying industries, releases various concentrations of heavy
metals. Metal ion such as Cd, Ni, Cr, Cu, Pb, Zn, Mn and Fe are commonly detected in both
natural and industrial effluents. Among these, textile industries and dying industries are the
ones that pose major environmental issues, because they produce coloured waste water that
heavily pollute the environment. From certain studies, it was found that neem and activated
carbon has the ability to reduce metal concentration by certain processes. So certain
experiments are done using neem leaves and activated charcoal on wastewater collected from
Kripesh Textile Industry Pappinessery in Kannur, which has several components that
constitute to the increased level of pollution in the environment. Neem being antibacterial and
a good biosorbent, helps in reducing the toxicity present in industrial wastewater and to
improve its quality. Activated carbon purify and absorb heavy metals present in waste water.
Here we are comparing the efficiency of neem and activated carbon in removing toxicity
from wastewater.
