Special Issue Information

Dear Colleagues,

The water industry is one of the few modern sectors that has not yet experienced or benefited from significant infrastructure reduction. Additionally, it requires more land and energy due to the growing volumes of water that need to be treated over time. Over the past decade, there has been increasing interest in discovering new technologies and treatment processes that enable cost savings in both capital and operational expenses while also adhering to environmental sustainability and circular economy principles. The development of hybrid wastewater treatment technologies has led to significant inroads being made in the water sector, enhancing treatment efficiency and reducing costs. One example is a combination of physico-biological treatments allowing for the degradation of hard-to-break or toxic molecules.

This Special Issue, titled “Latest Research on Wastewater Treatment and Recycling”, invites high-quality contributions that explore recent advancements in innovative water and wastewater technologies designed to minimize energy consumption and align with the principles of sustainability and the circular economy. Other relevant topics include bioremediation, bioaugmentation, physico-chemobiological combined treatments, phytoremediation, the use of catalysts, stimulators, etc.

A pilot-scale treatment system was developed to manage winery wastewater (WWW) generated by small and medium wineries. The system incorporated three stages: pre-treatment for suspended solids removal and a two-step aerobic biotreatment. The biotreatment phase utilized a bioaugmented bioreactor with encapsulated Pseudomonas putida F1, employing the Small Bioreactor Platform (SBP) technology. This innovative encapsulation method enhanced the breakdown of recalcitrant compounds and accelerated the biodegradation process. The second reactor was operated as a Sequence Batch Bioreactor (SBR) to remove the remaining organics and solids. Over the 100 days of operation, the mean WWW flow rate was 0.5 m3/d with average organic loads of 3950 mg/L COD (chemical oxygen demand) and 2220 mg/L BOD (biological oxygen demand), operating with a hydraulic retention time (HRT) of 4 days. Reductions of up to 96% in BOD and 90% in COD values were observed with stable removal rates over time. The novelty of this study is that it offers a new, effective aerobic biological treatment process, embracing bioaugmentation of encapsulated biomass followed by SBR for WWW with a relatively short HRT, high organics removal, and a stable treatment process. The effluent quality from this treatment system met the regulatory requirements for release to a municipal wastewater treatment plant and potentially also for irrigation. Full article
