Pharmaceutical contamination threatens both humans and the environment, and several technologies have been adapted for the removal of pharmaceuticals. The coagulation-flocculation process demonstrates a feasible solution for pharmaceutical removal. However, the chemical coagulation process has its drawbacks, such as excessive and toxic sludge production and high production cost. To overcome these shortcomings, the feasibility of natural-based coagulants, due to their biodegradability, safety, and availability, has been investigated by several researchers. This review presented the recent advances of using natural coagulants for pharmaceutical compound removal from aqueous solutions. The main mechanisms of natural coagulants for pharmaceutical removal from water and wastewater are charge neutralization and polymer bridges. Natural coagulants extracted from plants are more commonly investigated than those extracted from animals due to their affordability. Natural coagulants are competitive in terms of their performance and environmental sustainability. Developing a reliable extraction method is required, and therefore further investigation is essential to obtain a complete insight regarding the performance and the effect of environmental factors during pharmaceutical removal by natural coagulants. Finally, the indirect application of natural coagulants is an essential step for implementing green water and wastewater treatment technologies.

Membrane Treatment

The present Special Issue brought together recent research findings from renowned scientists in this field and assembled contributions on advanced technologies that have been applied to the treatment of wastewater and drinking water, with an emphasis on novel membrane treatment technologies. The 12 research contributions highlight various processes and technologies that can achieve the effective treatment and purification of wastewater and drinking water, aiming (occasionally) for water reuse. The published papers can be classified into three major categories. (a) First, there are those that investigate the application of membrane treatment processes, either directly or in hybrid processes. The role of organic matter presence and fouling control is the main aim of the research in some of these studies. (b) Second, there are studies that investigate the application of adsorptive processes for the removal of contaminants from waters, such as arsenic, antimony, or chromate, with the aim of the efficient removal of the toxic contaminants from water or wastewater. (c) Lastly, there are studies that include novel aspects of oxidative treatment such as bubbleless ozonation.

Real Time Applications

: Many studies reported the application of natural coagulants in removing pollutants with the help of the coagulation process, and coagulants showed their efficiency in comparison to the literature available. Yet, the utilization or acceptance of these coagulants in treating industrial wastewater is very low. Thus, there is a need for a strategy for enhancing the potential usage of coagulants for water treatment, presenting prevailing options and efforts for the development of coagulants. The utilization of coagulants can be improved by showing their efficiency in comparison to the advanced treatment technologies available in the present scenario. The coagulation efficiency with natural coagulants can be enhanced by mongrelizing the coagulants with other coagulants, enhancing the purity during extraction procedures, and by coalescence of coagulants. However, the research on natural coagulants are quite encouraging, perception of sustainable assessment studies revealed that commercialization/acceptance of coagulants for treatment options are hindered by their applicability and feasibility in real-time applications, and utilization of coagulants ignore the socioeconomic, ecological and technical aspects. The present review mainly focuses on the issues related to natural coagulants for clarifying the uncertainties and simultaneously moving the water industries to be more sustainable.

The suspended and dissolved particles presented in the water and wastewater in the size of 1-1000 nm which is more toxic and it causes severe effects to the aquatic life and living organisms. Nanotechnology is the method, which is newly developed in this world, to remove the very tiny particles presents in the water as well as wastewater with the help of nano-particles. Many nano-particles were used to remove the toxic contents presented in water and wastewater such as heavy metal concentration, dyes and some of the virus and bacteria etc. Compared to various nano-materials, Graphene is the type of smart material which is derived from the graphite, most widely used in all industrial sectors for various purposes. This review paper discussed about the importance of graphene usage in water and wastewater treatment technologies in recent days.

Life On Earth

Research aimed at solving important environmental problems at all scales ranging from global to individual will continue to be an essential part of the process by which sustainability of life on earth may be achieved. Solutions to environmental problems that relate to water are especially critical to this process and are likely to involve use of innovative technologies that emerge from research with sufficient promise to justify their development, a process that evaluates them at a scale that will yield engineering design parameters and confidence in their technical performance and economic value. Privatization of water and wastewater systems and mergers of equipment manufacturers may provide the economic bases needed for development of innovative water and wastewater treatment technologies in the 21st Century that have emerged from research in the 19th and 20th Centuries but have not as yet been fully developed or adopted.
