Towards sustainable wastewater treatment by biological methods - A challenges and advantages of recent technologies

Water is one of the most emerging substances on earth. All living things, including plants and animals, must have water to survive. Rapid urbanization and industrialization afford several pollutants, and their derivatives, which are discharged into the environment. The source of the pollutants includes domestic agriculture, nutrients, and industrial water, which are highly toxic to living organisms. In the current scenario, environmental laws have become stringent towards health, economy, and reduction of pollution. Hence it has become an essential need for the current environment to protect water from pollutants or need cost-effective strategies to protect water from getting polluting. The convention methods have several disadvantages; however, biological method attracted much more attention in recent years. The current objectives of the paper are to make a wide range of reviews on the recent bio-remedies role in wastewater treat-ment. Also discussed it's the advantages and limitations of bio-remedies technologies.

Automated summary

Water is vital for all living things on earth, and protecting water from pollution has become an essential need due to rapid urbanization and industrialization. Traditional methods of water treatment have drawbacks, but biological methods have gained more attention in recent years. This paper aims to review the role of bio-remedies in wastewater treatment, along with their advantages and limitations.
