“…In nature, one of wastewater treatment processes that occur spontaneously is where bacteria or other micro-organisms in the wastewater stream digest the sewage and other organic matters, yielding new micro-organisms, carbon dioxide and others [8]. In community, wastewater treatment plant is to speed up the natural processes from which the water is purified.…”

The global agricultural sector consumes a large amount of fresh water for irrigation. Less than half of agricultural wastewater is properly treated before discharging to environment or recycling. Treatment of agricultural wastewater for reuse in irrigation can alleviate burden on water resources as well as protect the environment from detrimental effects caused by various organics, pesticides, and soluble ions in the wastewater stream. This work reviews several current membrane technologies that are applied at removing the pollutants in agricultural wastewater. Subsequently, several strategies to further improve membranes' performance are highlighted. The advancement of materials science at the nanometer scale can assist the fabrication of membranes with higher selectivity of pollutant removal, higher permeate flux, and lower membrane fouling.

“…98 The sludge composting process is composed of three stages based on evolution in temperature, including the growth of mesophilic microbiota, the activation of thermophilic microbiota and the maturation phase which involves a diminution in temperature and reactivation of mesophilic population. 99 General technologies for sludge composting include windrows composting (conventional system), aerated static piles, bunkers, and in-vessel systems. 100 Sludge composting is not only a good cultivation matrix and soil additive, but also regarded as a slow release fertilizer.…”

Sludge is regarded as a potential source to achieve valorization via strategies such as resource recovery, sludge based adsorbents preparation, bioflucculants production, sludge manufacturing construction materials preparation, sludge composting and thermal valorization, which are currently common and effective strategies. Appropriate treatment strategies of sludge are of great importance worldwide for the fast growing population and rapidly increasing waste. This mini review summarized some widely used and effective strategies to achieve sludge valorization based on whether the strategy would utilize or reuse the potential of sludge to obtain valuable product and eliminate secondary pollution. Anaerobic digestion of sludge is perceived as a potentially cost‐effective method to achieve sludge reduction and resource recovery including carbon, nitrogen, phosphorus resource recovery coupled with other technologies. Utilizing sludge as raw material for preparation of valuable products including sludge based adsorbents, bioflocculants and construction materials is another aspect to achieve sludge valorization. Sludge composting and thermal valorization are also introduced in the mini review since the two strategies could also achieve sludge valorization. In addition, the strategies mentioned were discussed and analyzed in the mini review from environmental and economic aspects. © 2017 Society of Chemical Industry

“…The paramount objective of the processes carried out in wastewater treatment plants is to minimize the hazards that wastewater could cause in the environment. These hazards arise from dangerous, often toxic, contaminants, that after cleaning the water are found in sewage sludge [2]. For this reason, the sludge must be pre-processed prior to utilization (e.g.…”

“…Although exergy performance assessments of the waste water treatment plants have been widely considered [6], [9]-[18], exergy analysis of the treatment of sewage sludge with cavitation pretreatment is also greatly required, as the methods based on hydrodynamic cavitation are currently being intensively developed [2], [8], [19]- [23]. Despite the fact that the presented results are valid only for assumed data, the methodology described in this article may also be used for real data from industrial plants to show the exergetic potential of their modification.…”

A number of papers present exergy analyses of various wastewater treatment systems. The current development of these systems is mainly aimed at improving their energy efficiency, reducing the share of sludge subject to storage, and reducing their harmfulness. Some of these systems can be supported by the use of the cavitation phenomenon in the processing. The generation of cavitation requires, however, the use of devices or machines and thus additional energy consumption. Therefore, this treatment should be objectively justified, e.g. through exergy analysis, which takes into account not only the amount of energy used in processes, but also its quality. The paper treats the methodology for determining the impact of the use of cavitation in the exergy balance of sewage sludge treatment system. Then, it presents the results of an exemplary analysis comparing sewage sludge treatment systems (with and without application of cavitation phenomenon) in which biogas is produced during the fermentation, then burned in a co-generator, finally receiving useful energy in the form of electric current and hot flue gas stream.
