An optimization of reverse osmosis (RO) networks for seawater desalination with spiral-wound modules (SWM) was presented in this work. The membrane transport model, which based on the mass and momentum equations, took into consideration longitudinal variation velocity, pressure, salt concentration modules. pressure exchanger (PX) included RO superstructure, salinity increase caused by volumetric mixing PX considered. results obtained from model were compared actual plant operational data...
Abstract Imino hypercrosslinked polymers (NH‐HCPs), amino (NH 2 ‐HCPs), and carboxyl (COOH‐HCPs) were synthesized through cross‐linking Friedel‐Crafts reactions to serve as highly efficient adsorbents for doxycycline hydrochloride (DOX) in water. These polymers, NH‐HCPs, NH ‐HCPs, COOH‐HCPs, exhibited specific surface areas measuring 450, 267.576, 94.39 m /g, respectively. The adsorption kinetics of DOX onto these consistent with the pseudo‐second‐order model, while isotherms followed...
Novel polymers applied in economic membrane technologies are a perennial hot topic the fields of natural gas purification and O2 enrichment. Herein, novel hypercrosslinked (HCPs) incorporating 6FDA-based polyimide (PI) MMMs were prepared via casting method for enhancing transport different gases (CO2, CH4, O2, N2). Intact HCPs/PI could be obtained due to good compatibility between HCPs PI. Pure permeation experiments showed that compared with pure PI film, addition effectively promotes...
Increasingly strict constraints on the boron concentration for safe drinking and irrigation water present a tremendous challenge design of seawater reverse osmosis (RO) desalination systems. This work presents an optimization study RO network with permeate split (PS) under restrictions. Front part permeates better quality higher flux are sent directly to product, back reprocessed in pass 2 high pH value. The irreversible thermodynamic model is employed describe membrane transport behavior...
We presented economic, energy, exergo-economic, and environmental analyses multiobjective optimization (MOO) of seawater reverse osmosis (RO) desalination systems with boron restrictions. Exergo-economic unit cost for flows exergy destruction components were included. Life cycle assessment (LCA) principles the contributions construction operating introduced. An improved augmented ε-constraint method was adopted solving MOO problems. Unnecessary iterations avoided by bypass parameter. Results...
In this work, the two-phase flow behavior of a falling film on horizontal smooth and finned tube systems was investigated compared using three-dimensional computational fluid dynamics model based volume method. The established to capture microscopic gas–liquid interface for tubes. film, including liquid spreading, thickness, velocity distribution, effect Reynolds number (Re) systematically. results show that spreads rapidly forms thickness distribution "crest-stable-crest", while axial...
In the production of acrylic acid, concentration acid solution from adsorption tower was low, which would lead to significant energy consumption in distillation process purify along with a large amount wastewater. Reverse osmosis (RO) proposed concentrate aqueous taken specific tray absorption tower. The effects operating conditions on permeate flux and retention were studied two commercial RO membranes (SWC5 SWC6). When pressure 4 MPa temperature 25 °C, fluxes about 20 L·m−2·h−1. acetic...
Simultaneous optimization of size and operation for the seawater reverse osmosis (RO) system is proposed through a superstructure-based mixed-integer differential-algebraic programming approach. The influences operating conditions on performance pumps, RO membrane, properties are considered. permeate split (PS) design, interstage (ISPS) on–off model could give more operability cost saving. For constant feed conditions, nearly profiles control variables obtained with larger water tank....
Two-stage reverse osmosis (RO) processes with intermediate concentrate demineralization (ICD) provide an efficient strategy to treat brines high CaSO4 contents and reduce discharge. In this paper, SRO is treated using ICD remove then mixed a PRO for further desalination in SRO, thereby reducing the discharge of concentrate. We investigate selection degradation scale inhibitors, as well seeded precipitation two-stage RO process ICD, achieve water recovery rate. A inhibitor added restrain...
Horizontal-tube falling film evaporators (HFE) are widely used in the thermal desalination industry due to their increasing advantages. The liquid distribution state of tube bundle directly affects heat transfer performance evaporator. To improve uneven among rows, a balanced structure (BDS) that can balance HFE was proposed. A general distributed parameter model built describe steady-state with and without BDS, taking into account different odd even rows. is applied simulate multieffect...
Capacitive Deionization (CDI) technology represents a potent approach towards energy-efficient and sustainable access to potable water, with minimal environmental impact. However, the ion removal capacity of CDI systems remains inadequate for desalination saline water. Herein, mesopore-enhanced graphene foam modified hydrophilicity via O2-plasma treatment (MGFP) is proposed ultrahigh CDI. This developed MGFP encompasses abundant mesopores, outstanding electrical conductivity good...
