“…Time-varying RO processes, like batch and semi-batch RO and pulse-flow RO, have been reported to have high resistance toward fouling, and in particular, scaling [17][18][19][20]. Closed-circuit RO (CCRO) is a semi-batch RO process introduced by Efraty et al [21] and is commercially distributed by Desalitech (DuPont).…”

Cost-efficient operation of inland brackish water reverse osmosis (BWRO) demands a high recovery. As recovery of BWRO is often limited to scaling, antiscalants (AS) are applied, whose environmental impact is disputed. In this paper, different systems (conventional single-and two-stage plug flow RO (PFRO) and closed-circuit RO (CCRO)) were simulated in various configurations (AS dosing, ion exchange (IEX) pretreatment, elements per vessel) to determine the recovery limiting factor for a hard feed. The novel proposed IEX-CCRO reached the highest recovery without AS dosing. PFRO configurations had lower recoveries, mainly due to hydraulic limitations. Utilizing RO brine reduced both the water demand and salts necessary for IEX regeneration.

“…The HDH system has a simple construction, so it is easy to maintain compared to other thermal and membrane technologies (Aref et al 2021). Despite the HDH systems, technologies such as multi-stage flash distillation (MSF) and multiple effect distillation (MED) need intensive heat energy sources, and reverse osmosis (RO) systems should be placed where there is an electricity supply (Liberman et al 2020).…”

Humidification–dehumidification desalination (HDH) is one of the suitable methods for desalination of saline and brackish water in a small scale. In this research, a HDH desalination method with a direct contact dehumidifier has been analyzed theoretically and experimentally. The setup consists of two similar packing towers for humidification and dehumidification, 10 inches in diameter, which are filled up to 1 m with Rushing packing. In this new HDH configuration, seawater and freshwater recirculation has been used in humidifier and dehumidifier sections, respectively. A steady-state mathematical model based on the mass and energy equations for each system component is presented. The effect of various input parameters on the freshwater production, gain output ratio (GOR) and specific energy consumption has been investigated. The results revealed that the inlet seawater and air temperature to the humidification tower had the highest and the lowest effect on the produced freshwater, respectively. Also, the maximum value of the GOR is 3.3, which is obtained in the equilibrium condition of the dehumidifier. The experiments show that the freshwater production of the proposed HDH device is 300 L/day, which can provide water for domestic consumption of a small family.
