“…Recovering average cost for each P removal structure allows us to compare these structures to other technologies. For example, it is estimated that removal of P in wastewater treatment plants varies between $88 and 1760 per kg of P removed. , The wide range of costs reflects the different technologies, influent P concentration, and scale of wastewater treatment. Stormwater treatment areas, a reliable BMP to reduce total P loads, have a reported average cost of $921 per kg of P removed .…”

Excess phosphorus (P) is a major pollutant in aquatic systems. Phosphorus removal structures, landscape-scale filters designed to capture dissolved P from runoff, drainage, and wastewater offer promise in curbing P pollution. While the environmental benefits of various P removal structures are well documented, the cost-effectiveness of each structure's ability to sequester P is lacking. In this study, we compare the costeffectiveness of P removal of the most prominent P removal structures. Specifically, we calculate the average cost per kilogram (kg) of P removed by eight different P removal structures across a range of parameter assumptions. Absent constraints, we found that (1) larger structures that use (2) regionally available phosphorus sorption materials that are (3) byproducts of industrial production (e.g., metal shavings and steel slag) rather than manufactured are more cost-effective. The average cost of P removal for most structures varies from $100 to 1300 per kg in our baseline estimations, which is comparable to the average cost for wastewater treatment. This work provides further information to guide the optimal implementation of P removal structures for conservationists.

“…Based on the size exclusion principle, a membrane is a selective layer that permits some components to pass through while blocking unwanted constituents [ 23 ]. Researchers have focused a lot of attention on the removal of pathogens using advanced membrane technologies, such as membrane distillations, nanocomposite membranes, membrane bioreactors, and photocatalytic membrane reactors, in addition to traditional membrane filtration techniques [ 27 , 28 ]. Advanced membrane technologies provide the ability to combine filtration properties with other functionalities, hence enhancing the properties of the original membrane [ 29 ].…”

“…In order to improve the understanding and the representation of the individual foulants, starting with the late 1980s, mathematical models have been developed to include the contribution of the SMPs into the MBR bioprocesses either individually [ 59 , 60 ] or as an extension of the ASMs [ 61 , 62 , 63 ]. This stage represents the inception of the hybrid biological models for MBRs, which continues with the inclusion of further aspects such as processes associated with EPS [ 64 , 65 , 66 ]. These new representations enhance the performance of the ASMs in the modelling of the biomass kinetics inside the MBR without the need for calibration with experimental data.…”

Prolonging the Life Span of Membrane in Submerged MBR by the Application of Different Anti-Biofouling Techniques

The membrane bioreactor (MBR) is an efficient technology for the treatment of municipal and industrial wastewater for the last two decades. It is a single stage process with smaller footprints and a higher removal efficiency of organic compounds compared with the conventional activated sludge process. However, the major drawback of the MBR is membrane biofouling which decreases the life span of the membrane and automatically increases the operational cost. This review is exploring different anti-biofouling techniques of the state-of-the-art, i.e., quorum quenching (QQ) and model-based approaches. The former is a relatively recent strategy used to mitigate biofouling. It disrupts the cell-to-cell communication of bacteria responsible for biofouling in the sludge. For example, the two strains of bacteria Rhodococcus sp. BH4 and Pseudomonas putida are very effective in the disruption of quorum sensing (QS). Thus, they are recognized as useful QQ bacteria. Furthermore, the model-based anti-fouling strategies are also very promising in preventing biofouling at very early stages of initialization. Nevertheless, biofouling is an extremely complex phenomenon and the influence of various parameters whether physical or biological on its development is not completely understood. Advancing digital technologies, combined with novel Big Data analytics and optimization techniques offer great opportunities for creating intelligent systems that can effectively address the challenges of MBR biofouling.
