“…The objective of the hybrid RO‐CDI system study is to analyze the enhancement in the quantity of water production and to assess its energy requirements in comparison with two‐stage RO. This paper uses the experimental data of brackish water found in 26 to analyze the suggested hybrid RO‐CDI system. In order to calculate the permeate flux and concentration, a computer program in the FORTRAN language was developed incorporating Broyden's method to simultaneously solve highly nonlinear membrane transport equations.…”

“…RO simulation means the estimation of the solute flux and prediction of salt rejection. The model presented in 29 was used to predict the permeate flow rate and permeate concentration for the experimental data given in 26. The model parameters used in the simulation were obtained from 28, 29.…”

“…In a recent work 25, the use of an RO membrane prior to multi‐effect evaporators to minimize wastewater in the paper industry has been proposed. In order to treat the industrial refinery effluent, Abbasi et al 26 have presented experimental data on a hybrid pilot plant (microfiltration‐ultrafiltration‐RO).…”

Hybrid Reverse Osmosis‐Capacitive Deionization versus Two‐Stage Reverse Osmosis: A Comparative Analysis

Reverse osmosis (RO) is a high-pressure single-phase desalination process used to obtain freshwater from seawater/brackish water. The RO system shows high energy consumption for a given unit volume of pure water produced. The reported hybrid system of RO and capacitive deionization (CDI) aims at improving the RO water recovery and minimizing energy consumption. The RO-CDI system is simulated and compared with two-stage RO, to determine the effectiveness of the new hybrid system. The energy recovery from RO brine was also studied. The specific energy consumption by two-stage RO for two different arrangements of the energy recovery device is higher than for RO-CDI. The hybrid RO-CDI system is energy efficient for the production of freshwater from brackish water.

“…Among the different membrane technologies, MF/UF-RO following suitable pretreatments with regard to feed water quality such as dissolved air flotation, flocculation and coagulation has shown promising results in oily wastewater treatment [29][30][31]. However the number of WWTPs based on such a technology is scanty, especially in large capacities which may have economic benefits considering economy of scale.…”

This article discusses the use of a multi-cyclone separator, which is a simplified form of a degassing hydrocyclone, in the separation of sweeping nitrogen bubbles and dissolved oxygen from water. The motion of the nitrogen bubbles and mass transfer of dissolved oxygen is discussed. It was observed that the Sauter mean diameter and gas volume in the swirling flow region as well as the total gas holdup increased as the volumetric ratio of gas to liquid flow increased. Almost all bubbles were found to exit through the gas outlet, indicating optimum performance of the bubble-separation process. The multi-cyclone separator was found to achieve good performance for the mass transfer of oxygen from water to nitrogen. This work is important in predicting the destination of bubbles and dissolved gas in swirling flow.
