**4. Conclusion**

The treatment of wastewater is crucial because of its effect on the environment. Due to increased urbanization and industrialization, wastewater generation and treatment have become a growing concern in the twenty-first century. Wastewater treatment ensures the long-term viability of the ecosystem. Many wastewater treatment options are employed to address the problem of growing environmental pollution, including physical, chemical, and biological (primary to tertiary treatment) technologies. The employment of some treatment strategies has the potential to produce secondary contaminants. The effective implementation of wastewater treatment options in water resource management necessitates planning, activity, design, storage, and operation. Advances in wastewater recycling have made it possible to produce water of virtually any quality. Water recovery systems incorporate a variety of safety precautions to reduce the environmental risks associated with various reuse applications. Continuous advancements have been made in the fundamental science of water treatment methods, as well as the innovation used in the process. However, based on the known treatment methods, attaining considerable wastewater treatment with a single treatment technology is difficult. Under the present conditions, improved or integrated wastewater treatment technologies are critically required to ensure high-quality water, reduce chemical and biological pollutants, and enhance industrial production operations. Integrated approaches, which may overcome the limits of single treatment techniques, seem to be viable options for efficient wastewater remediation. Regrettably, most viable treatment techniques are on the small scale and lack commercial application feasibility.
