Wastewater Problems Analysis and Their Treatment Using Eco-friendly Techniques: An Overview

In the current changing environment where almost all activities involve the use of clean water, waste water is discharged in a huge amount, which not only pollutes the environment but also causes many diseases in human as well as in animal. 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. In the current study, some environmentally friendly wastewater treatment techniques—such as seaweed-based flocculants, mangrove plants, phyto-accumulation, Phyto remediation etc.—are discussed in order to better understand how they work and to advocate for their widespread use.
