Municipal Waste Water Treatment using Plant Adsorbents

Access to safe drinking water is still a dream to certain category of people in urban and peri-urban areas of many
important cities in India. The waste water contains a wide range of toxic derivatives, in particular heavy metals,
aromatic molecules and dyes which causes a serious environmental problem owing to their potential human toxicity. Therefore, there is a need to develop technologies that can remove toxic pollutants present in waste water. Adsorption is a procedure of choice for treating industrial effluents, and a useful tool for protecting environment. This research aims to determine the best method for sustainable water purification using polysaccharides obtained from locally available waste from plants such as fruit seeds, leaves, and tubers that will help in purifying water. Large amount of municipal waste water released into environment can be treated and reused for gardening, cleaning, and washing purpose using this proposed filtration system. A unique filtration system was developed and the various types of wastewater (sewage, grey waste and dye effluent) were treated. After water analysis it was observed that the TDS was consumer acceptable, pH was neutral and we also obtained permissible limits of Mg/Fe concentration.
