“…In addition to this, many scientists also tried the combination of MF–NF–RO membrane systems along with membrane distillation (MD)/membrane chemical reactor (MCR) units, for desalination of seawater (Drioli et al, 2006; Tian et al, 2020; Tufa et al, 2019). Also, combination of MF–UF and UF–RO systems has been successfully applied for the treatment of refinery wastewater (Nadjafi et al, 2018). Hybrid membrane technology has been demonstrated for the removal of dangerous and hazardous chemical components from the refinery wastewater.…”

“…The efficiency for removal of salts and organic chemicals from the refinery wastewater was very high for UF–RO than that of MF–UF system. Also, the treated wastewater had fallen in the acceptable category for the utilization in the boilers and coolants or environmental discharge standards (Nadjafi et al, 2018). Treatment of municipal wastewater for the removal of salinity, nutrients, and toxic pollutants by using combination of RO and membrane bioreactor (MBR) has also been reported by Cartagena et al (2013) in which almost 100% removal of TSS and 98% COD removal by using flat sheet combined with hollow fiber module was demonstrated from wastewater.…”

Different industrial activities such as agro‐food processing and manufacturing, leather manufacturing, and paper and pulp production generate highly saline wastewater. Direct discharge of saline wastewater has resulted in pollution of waterbodies by very high magnitudes. Consequently, an enormous number of pollutants such as heavy metals, salts, and organic matter are also released into the environment threatening the survival of human and biota. Saline wastewater also has significant effects on survival of plants, agricultural activities, and groundwater systems. Several treatments and disposal technologies are available for saline wastewater, but the selection of the most appropriate treatment and disposal technology still remains a major challenge with respect to the economic or technical constraints. Considering the sustainable management of saline wastewater, the present review is an attempt to compile the existing and emerging technologies for the treatment of saline wastewater. Among all the individual and hybrid technologies, land‐based treatment systems are proven to be the most efficient technologies considering the energy demands, economic, and treatment efficiencies. Likewise, new and sustainable technologies are the need of hour integrating both the treatment and management and the resource recovery factors along with the ultimate goal of the protection in terms of human health and environmental aspect.

“…In fact, high-purity water with an electrical conductivity lower than 0.06 µS cm −1 is a critical factor for several industrial applications, such as semiconductor manufacturing and pharmaceutical formulations [6], as well as for steam generation in high-pressure boilers in the petrochemical industry [7]. These boilers require high-quality water to protect equipment and to prevent scaling and corrosive processes [8], in addition to avoiding other undesirable problems, such as a reduced heat exchange rate and increased fuel consumption, reduced steam production, the overheating and rupture of pipes, and the fouling of instruments and control devices [9].…”

“…In this context, boiler feed water requires a very refined treatment, which generally employs conventional treatment systems (coagulation/flocculation plus sedimentation or flotation) together with one or more advanced ones [10], such as ion exchange resin [1,11], reverse osmosis (RO) [8], electrodialysis reversal (EDR) [12], and electrodeionization (EDI) [13,14].…”

This study investigated a hybrid membrane and electro-membrane separation process for producing demineralized water from tertiary petrochemical effluent, reusing it as feeding water for high-pressure boilers for steam generation. The effluents were treated in a pilot plant with a 1 m3 h−1 capacity by using a hybrid process of ultrafiltration (UF), reverse osmosis (RO), and electrodeionization (EDI). The physicochemical parameters of interest and maximum limits in industrial water were pre-determined by the industries. Operating parameters such as flow rate, pressure, percentage of recovery, and electric current were monitored, along with the frequency of chemical cleaning. The UF and RO systems operated with average permeate fluxes of 17 ± 4.06 L h−1 m−2 and 20.1 ± 1.9 L h−1 m−2, respectively. Under optimal operating conditions (flow rate of 600 L h−1, voltage of 22.2 ± 0.7 V, and electric current of 1.3 A), EDI produced high-quality water with an average electrical conductivity of 0.22 μS cm−1. Thus, the industrial water produced reached the quality required for reuse as make-up water for high-pressure boilers in the petrochemical industry. In addition, the specific energy consumption; the use of chemicals, spare materials, equipment; and labor costs were determined to support the technical feasibility study for implementing an industrial plant with a 90 m3 h−1 producing capacity. This resulted in a cost of USD 0.64 per cubic meter of demineralized water produced, a cost similar to values reported in the literature.

“…Effluents from industrial sectors, including paper, plastic, leather, food, and pharmaceutical industries, contain numerous pollutants such as dyes, heavy metal ions, pesticides, oils, and organic compounds [1][2][3][4][5]. Research has recently been focused on using agricultural wastes to remove pollutants from wastewater [1,2,6] because these natural materials are inexpensive, abundant, renewable, and eco-friendly. They include orange and banana peels, cotton, wool and date palm fibers, rice husk, coconut tree, sawdust, alfa, sisal, luffa, among others [7,8].…”

The significance of using date palm surface fiber as a biosorbent to remove pollutants from wastewater is evaluated. This material, which has advantages over other natural adsorbing materials, for being inexpensive, renewable, eco‐friendly, and available in large scale worldwide, has been widely used for the removal of several types of pollutants such as acid and basic dyes, heavy metals, pesticides, oils, and organic compounds. In addition to its use as an effective biosorbent to remove pollutants from wastewater, date palm surface fiber exhibits wide future perspectives in several other applications.
