A dual“waste-to-resource”innovation in nutrient enrichment and recovery from domestic black water using a sea salt bittern(SSB)-driven forward osmosis(FO)process is proposed and *** performance of SSB as a“waste-to-resource”draw solution for FO was first evaluated.A synthetic SSB-driven FO provided a water flux of25.67±3.36 L/m2 h,which was 1.5-1.7 times compared with synthetic seawater,1 M NaCl,and 1M *** compromised performance regarding reverse solute selectivity was *** compensation,the enhanced reverse diffusion of Mg+suggested superior potential in terms of recovering nutrients in the form of struvite *** nutrient enrichment was performed using both the pre-filtered influent and effluent of a domestic septic *** 80%of phosphate-P recovery was achieved from both low-and high-strength black water at a feed volume reduction up to 80%^90%.With an elevated feed pH(~9),approximately 60%-85%enriched phosphate-P was able to be recovered in the form of precipitated *** the enrichment performance of total Kjeldahl nitrogen(TKN)largely differed depending on the strength of black *** concentration factor(i.e.,3-folds)and retention(>60%)of TKN was obtained in the high-nutrient-strength black water at a feed volume reduction of 80%,in comparison with a weak TKN enrichment observed in low-strength black *** results suggested a good potential for nutrient recovery based on this dual“waste-to-resource”FO system with proper management of membrane cleaning.

This work investigates the performance of various forward error correction codes, by which the MIMO-OFDM system is deployed. To ensure fair investigation, the performance of four modulations, namely, binary phase shift keying(BPSK), quadrature phase shift keying(QPSK), quadrature amplitude modulation(QAM)-16 and QAM-64 with four error correction codes(convolutional code(CC), Reed-Solomon code(RSC)+CC, low density parity check(LDPC)+CC, Turbo+CC) is studied under three channel models(additive white Guassian noise(AWGN), Rayleigh, Rician) and three different antenna configurations(2×2, 2×4, 4×4). The bit error rate(BER) and the peak signal to noise ratio(PSNR) are taken as the measures of performance. The binary data and the color image data are transmitted and the graphs are plotted for various modulations with different channels and error correction codes. Analysis on the performance measures confirm that the Turbo + CC code in 4×4 configurations exhibits better performance.

forward osmosis(FO), as an emerging technology, is influenced by different factors such as operating conditions,module characteristics, and membrane properties. The general aim of this study was to develop a suitable(flexible,comprehensive, and convenient to use) computational tool which is able to simulate osmosis through an asymmetric membrane oriented in pressure retarded osmosis(PRO) mode in a wide variety of scenarios. For this purpose, an agent-based model was created in NetLogo platform, which is an easy-to-use application environment with graphical visualization abilities and well suited for modeling a complex system evolving over time. The simulation results were validated with empirical data obtained from literature and a great agreement was observed. The effect of various parameters on process performance was investigated in terms of temperature,cross-flow velocity, length of the module, pure water permeability coefficient, and structural parameter of the membrane. Results demonstrated that the increase in all parameters, except structural parameter of the membrane and the length of module led to the increase of average water flux. Moreover, nine different draw solutes were selected in order to assess the influence of net bulk osmotic pressure difference between the draw solution(DS) and feed solution(FS)(known as the driving force of FO process) on water flux. Based on the findings of this paper, the performance of FO process(PRO mode) can be efficiently evaluated using the NetL ogo platform.
