The scarcity of the most limited natural resource, "clean water" for daily use is decreasing day by day. So, the present study was done to assess various harmful effects of wastewater and techniques to overcome these effects through different plant-based wastewater treatment methods. There are few researches conducted to overcome the problem of wastewater biologically, the researchers used different plans to treat wastewater which absorb toxic substances up to a greater extent and clean the water efficiently.
