TL;DR: Among the WWTPs considered, soil biotechnology (SBT) obtained the lowest environmental impact in all the evaluated impact categories, except for eutrophication potential, and the results obtained from the evaluation of benefit from treated effluent reuse clearly indicate that there is a drop in the toxicity potential when the rate of Effluent reuse is increased.

TL;DR: It is concluded that conventional regression models generally overestimate particle Froude number for the non-deposition condition of sediment transport, while DT, GR and MARS outputs are close to their measured counterparts.

TL;DR: High adsorption capacity, reusability, fast kinetics and simple synthesis method indicate that prepared nanocomposite can be suggested as a high-performance adsorbent for Pb(II) removal from polluted water.

TL;DR: The thoughts and opinions collected during the closing session of the 6th IWA/WEF Water Resource Recovery Modelling Seminar 2018 are described, which presents a concerted and collective effort by individuals from many different sectors of the wastewater industry to offer past and present insights, as well as an outlook into the future of wastewater modelling.

TL;DR: A molecularly imprinted polymer was synthesized for the specific recognition of efavirenz and then applied as the SPE sorbent for its extraction from wastewater and surface water samples and showed better selectivity than did non-imprinted polymer.

TL;DR: The presented work aims at clarifying the current state-of-the-art in gas-liquid mass transfer modelling of oxygen and other gases, but also to direct academic research efforts towards the needs of the industrial practitioners.

TL;DR: The treatment techniques along with the characteristics of all such kinds of wastewater, including coal washery wastewater, are reviewed and the challenges and future perspectives are identified.

TL;DR: Tackling sewer leakage is of primary importance to today's environment in China and recommendations for the inspection of sewer systems and the rehabilitation of damaged sewers as well as the development of design and operation guidelines of municipal WWTPs tailored to the specific local sewage characteristics and other conditions are proposed.

TL;DR: It was observed that marshes and steppe areas decreased while water and agricultural areas expanded from 2005 to 2012, which could be the results of water transfers to the marshes from neighboring watershed.

TL;DR: Comparison of sawdust and alginate as carriers for degradation of phenol at high concentrations demonstrated that sawdust improved biodegrades better, and immobilized P53 into sawdust entrapped in sodium-alginate beads can be used for biodegradation purposes.

TL;DR: The TiO2 photocatalytic membrane is a feasible technology for RB 19 decolorization in wastewater by decreasing the contact angle, scanning electron microscopy and porosity and being coated with titanium dioxide.

TL;DR: Overall, the MWS could achieve efficient removal of nitrate under the simplest operating conditions and Thermodynamic parameters suggested that the adsorption process was exothermic, feasible and spontaneous in nature.

TL;DR: Sources of methane emissions of an anaerobic digester (AD) system at a municipal wastewater treatment plant with 260,000 population equivalent (PE) capacity were detected by a non-dispersive infrared (NDIR) camera and evaluated qualitatively and documented with photographs and video films.

TL;DR: Results show that a portion of the nitrogen was converted by nitrification-denitrification, and that traditional anammox proceeds simultaneously with SRAO.

TL;DR: It was found that the TC degradation kinetics in the Cu(II)/PDS/UV system can be divided into two parts and these two parts had good agreement with the pseudo-first-order kinetics model, respectively.

TL;DR: Thermodynamic studies show that adsorption of the heavy metals using SCG is spontaneous, endothermic and results in increased randomness at the solid/solution interface.

TL;DR: Two techniques of neuro-fuzzy (NF) and gene expression programming (GEP) are implemented for particle Froude number (Frp) estimation of the non-deposition condition of sediment transport in rigid boundary channels, proving the suitable accuracy and applicability of the NF method in Frp estimation.
