Forward osmosis (FO) is an emerging low energy membrane-based technology and can be applied if the diluted draw solution (DS) is directly utilized without additional recovery/treatment. In this study, FO process was applied for the treatment of textile industry wastewater using fertilizer as DS. This paper focuses on modelling and optimisation of FO process using machine learning techniques like Response Surface Methodology (RSM), Artificial Neural Network (ANN) and Adaptive Neuro-Fuzzy Inference System (ANFIS). To model the FO process, central composite design was utilized to examine the effect of initial draw concentration, initial feed concentration, time, initial feed pH and temperature on the water flux and reverse salt flux. The optimum water flux (8.527 Lm(-2).h(-1) (LMH)) and reverse salt flux (7.246 g.m(-2).h(-1) (GMH)) was obtained using initial draw concentration of 1.625 M, initial feed concentration of 1090 mg/L, reaction time of 90 min, initial feed pH of 7.33 and temperature of 35 degrees C. Under these conditions, FO performance was carried out experimentally and validated with the models. The model developed for the FO process by ANN and RSM was considerably better than that of other models in terms of precision of predicting the water flux and the reverse salt flux, respectively. About six different chemical fertilizer solutions were screened and tested at optimum conditions to identify the best suitable fertilizer DS for FO process using textile wastewater. The results indicate that Diammonium Phosphate (DAP) along with Potassium Chloride (KCl) fertilizer as DS gave better performance with respect to water flux. (C) 2020 Elsevier Ltd.

The adsorption of cyanogen halide gases (CNX) onto the surface of B-36 nanocluster was investigated using density functional theory (DFT). The results show that the N-head of CNX molecules interacts strongly with the B-36 nanocluster and adsorption sites on the edge of B-36 nanocluster are more reactive than those on other sites. The nature of the interaction and binding properties of CNX and B-36 nanocluster are calculated by molecular orbitals (HOMO and LUMO), topological analysis, global reactivity parameters, density of states, analysis of bond length and bond order. Based on the results, the electrical conductivity of B-36 nanocluster significantly increases in the presence of CNX molecules. These results suggest that the B-36 nanocluster could be a promising material in designing CNX sensors.

A novel cyclization reaction by using hexachloroacetone as C2 synthon has been studied. The optimal condition was obtained by synthesis of bibenzothiazole in the presence hexachloroacetone in water. Experimental results showed that the nucleophilicity of substrates played a key role in the cyclization reaction, and catalytical amount of oxygen in reactions was also vital to trigger ring fusion in the formation of target compounds. Accordingly, the mechanism of cyclization reaction was proposed: the thiazole ring is formed in the first place by a nucleophillic attack of 2-aminobenzenethiol, followed by CCl3 cleavage from hexachloroacetone. Then the second 2-aminobenzenethiol launches another nucleophilic attack, and three chloride ions leave to form the second thiazole ring. The method was applied to the substrates of 2,5-diaminobenzene-1,4-dithiol and benzene-1,2,4,5-tetraamine, respectively and two polymers of polyphenylene dithiazole and polyphenylene diimidazole were successfully prepared. The experimental conditions were mild, the yield was high and the application value was high.

This study presents the evaluation of an air conditioning system with enthalpy recovery for space heating and air humidification. Desiccant assisted air conditioning is potentially beneficial against other air conditioning processes in terms of air humidification, counteracting dry indoor air conditions during winter. Furthermore, the overall process can be operated efficiently relying on renewable energy sources. The objective of this work is to investigate a geothermal and desiccant assisted system for different system configurations experimentally and numerically during winter operation. The experimental investigation focuses on differences in system performance for two desiccant materials, lithium chloride and silica gel. Experimental results show that moisture recovery relying on a desiccant wheel with silica gel is beneficial against lithium chloride. An average moisture recovery efficiency of 0.83 was achieved for silica gel. Thermal comfort was maintained on a high level throughout the winter seasons investigated. Based on component and system simulation models, system performance is shown for different boundary conditions during winter requiring space heating and humidification to ensure comfortable indoor air conditions. The simulation results show a reduction in primary energy demand for heat supply by up to 54% by using a high efficient ground-coupled heat pump without backup system. (C) 2020 The Author(s).

Study on the effect of chloride ion ingress on the pore structure of the attached mortar of recycled concrete coarse aggregate

In this study, based on the porous interface of recycled aggregates (RA), the effects of chloride ion (Cl) ingress by drying-wetting cycles on the pore structure of recycled aggregate concrete (RAC) with a full replacement ratio under different temperatures conditions were investigated. Changes in the pore structure of the old and new mortars were determined by mercury intrusion testing. The surface morphology and morphological characteristics of the reaction products in the pores were observed via scanning electron microscopy. The results showed that the porosity, pore connectivity, fractal dimension and distribution of the pore size and pore volume were remarkably transformed by Cl ingress. During the wetting phase, the products dissolved and migrated between the pores and crystallized during the drying phase, and the increase in temperature promoted this process. With the dry-wet cycles, the original pore space was gradually divided and filled, forming a large number of new pores with smaller pore sizes. The model of RA partition-interface Cl ingress was presented based on the RA porous interface, and the mechanism of the effect of Cl ingress by drying-wetting cycles on the pore structure of RAC was in-depth analyzed.

Removal of selected emerging micropollutants from wastewater treatment plant effluent by advanced non-oxidative treatment – A lab-scale case study from Serbia

The presence of 48 emerging micropollutants was tested in influent and effluent from primary and secondary treatment at a municipal wastewater treatment plant (WWTP) in Serbia. Sixteen emerging micropollutants (active pharmaceutical ingredients, bisphenols, parabens and UV filters) had concentrations >LOQ (max. conc. 33.4 mu g/L). The removal efficiency of primary treatment ranged from 2.0% – 96.0%. In the case of secondary treatment, except for ketoprofen (61.0%), diclofenac (62.6%) and carbamazepine (- 20.0%), all other measured micropollutants had removal efficiency above 77.0%. Advanced non-oxidative lab-scale treatments were investigated. Powdered activated carbon (PAC) adsorption achieved removal efficiencies in the range 52.4-99.9%, novel coagulation with natural coagulant isolated from beans achieved removal efficiencies in range 3.2-99.9%, conventional coagulation with ferric chloride 3.12-96.4%, combined adsorption/coagulation 2.69-99.9% and combined PAC/ultrafiltration (PAC/UF) 60-99.9%. For most of the micropollutants, their removal efficiencies were similar to that reported in the literature. Novel natural coagulant showed significant potential compared to the conventional coagulant during a short episode of sub-optimal WWTP operation. When natural coagulant was applied as a part of an adsorption/coagulation hybrid process, there was no negative effect on PAC adsorption, while for conventional coagulant that was not always the case. Also, a structure property relationship (SPR) study revealed correlations between the removal efficiency of the majority of treatments applied and total polar surface area (TPSA) of the micropollutants.

Effect of the chloride environmental exposure on the flexural performance of strengthened RC beams with self-anchored prestressed CFRP plates

Carbon fibre-reinforced polymer (CFRP) plates are widely used to strengthen reinforced-concrete (RC) structures. At present, most studies focused on the short-term performance of strengthened RC beams with a prestressed CFRP plate, and very limited information is available on their durability, which is of importance in certain cases, such as high-piled wharfs and bridges in marine environments. This study investigates the effects of chloride environment exposure on the flexural performance of strengthened RC beams with self-anchored prestressed CFRP plates. In total, seven RC beams, four of which were strengthened by a self-anchored prestressed CFRP plate, were fabricated and tested under three-point bending. The testing parameters included 25% and 40% prestress level of the ultimate tensile strength of the CFRP plate, 5% and 10% tensile steel rebar corrosion ratio of mass loss and 10% and 20% anchor corrosion ratio in the chloride environment. The evolution of time-dependent prestress losses in the strengthened beam was determined, and the flexural behaviour of the strengthened beams was analysed. A theoretical model is proposed to predict the flexural strength of prestressed CFRP strengthened RC beams in a chloride environment. The experimental results indicated that the coupling of the corrosion expansion of the metal anchor and rebar in the chloride environment had a large negative effect on the flexural performance of the beams strengthened by the self-anchored prestressed CFRP plates. After exposure to the chloride ion solution, the failure mode of the RC beams strengthened by the prestressed CFRP changed from concrete crushing in the compression section to anchor pullout. The proposed model, which considered the effect of a chloride environment to predict the flexural strength of the strengthened beams, agreed well with the test results.

Vacuum-assisted diamine monomer distribution for synthesizing polyamide composite membranes by interfacial polymerization

Polyamide composite membranes are still required to promote their structure uniformity and desalination performance. Herein, a vacuum-assisted strategy was used to deal with this challenge by improving the distribution homogeneity of diamine monomer in porous substrates for typical interfacial polymerization. Laser scanning confocal microscope analyses demonstrate that the piperazine solution can be adsorbed in the microporous substrates with a very homogeneous and stable way. This uniform diamine distribution shows great advantages for synthesizing the selective layers of polyamide on the substrate surfaces via the interfacial polymerization of piperazine and trimesoyl chloride. The as-prepared polyamide layers with a circular size of 30 cm exhibit uniform structures including thickness less than 20 nm, cross-linking degree up to 100%, surface roughness lower than 20 nm and pore diameter about 0.41 nm. Therefore, the polyamide composite membranes present nanofiltration performances of ultrahigh rejection above 99.6% to Na2SO4 and high water permeability of 20 L/m(2) h bar. These membranes also show a promising selectivity for NaCl/Na2SO4 up to 196, which is higher than most of the commercial and the reported nanofiltration membranes in recent years.

Evaluation of ion content, productivity and essential oil quality of garlic under saline conditions and biochar and polyamine treatments

In 2018, a pot experiment was carried out to evaluate the performance and essential oil quality of garlic under salinity and biochar and polyamine treatments. Results showed that about 18 compounds were identified in garlic bulbs essential oil, some of which only induced by the salt stress, 20 % of biochar and putrescine treatments. Diallyl trisulfide and diallyl disulfide were the major constituents of essential oil. The 1-propenyl methyl disulfide and methyl allyl trisulfide were only induced by salt stress. The butyl propenyl sulfide was only produced in biochar treated plants under salt stress. Application of putrescine stimulated the synthesis of 3-ethenyl1,2-dithiane and 2-ethenyl-1,3-dithiane under normal condition and 3,5-diethyl-1,2,4, trithiolane under saline conditions. Overall, biochar and polyamines improved growth and essence quality of garlic under salinity, which may have related to sodium (Na+) and chloride (Cl-) reduction and potassium (K+), calcium (Ca2+), and K+/Na+ enhancement.
