Conventional desalination processes are considered as energy-intensive, as energy consumption represents 50–60% of water production cost. As an example, multistage flash evaporation (MSF), requires 19.58–27.25 kWhe/m3, and reverse osmosis (RO) 1.5–6 kWhe/m3. Thus, developing forward osmosis (FO), a membrane technology for water desalination considered as a potentially energy-efficient process, has gained growing interest. However, the technology is facing serious limitations concerning the availability of a high-performance draw solution and membrane, which represent the core of the process. In addition to the lack of energy-efficient recoverable draw solutes, as the regeneration process represents the main energy consumption of the overall FO process. In this paper, an updated state of the art of newly developed draw solutes such as deep eutectic solvents, ionic liquids, smart materials, and classical FO draw solutes have been carried out. Finally, FO technology challenges, opportunities, and future prospects have been discussed. Draw solutes have been categorized according to their recovery methods, innovations and draw solutes strengths and limitations have been critically reviewed. The necessity of theoretical energy consumption and water production costs estimation have been outlined, in addition to pilot-scale testing to demonstrate the process feasibility.

Seasonal use of pesticides can cause increased concentrations to be detected at potable water abstraction sites as a shock load which can be difficult for conventional treatment processes to deal with. Concentrations of pesticides above 0.1 µg/L in drinking water contravene the regulations as laid out in the Drinking Water Directive and cause significant reputational and financial impact to water companies. This review considers the relationships between the pesticides that have caused compliance failures and their physico-chemical properties, and factors such as weather and rainfall. It was found that over 50% of the pesticide compliance failures in England and Wales were caused by the molluscicide metaldehyde and that the majority of the problematic pesticides are considered to be polar and mobile. The review looks in further detail at five different pesticides with differing physico-chemical properties known to have caused compliance failures and to be of particular concern for water companies. In addition adsorption media which could be utilised in agricultural catchments were investigated to understand whether they could be applied to prevent the onward contamination of potable water sources.

These systems aim to utilise locally occurring water sources by collecting and using water within a discrete boundary. Alternative water technologies such as greywater and rainwater collection systems can reduce pressure on shallow groundwater resources, lessen infrastructure and maintenance costs of existing water systems by deferring new developments such as seawater RO desalination plants and wastewater treatment plants. Ultimately, large-scale HWS implementation can bring about the creation of a water trading market, either in the form of physical peer-to-peer water trading or via a credit-debit system. This review highlights the social, technical and administrative components and factors involved in establishing sustainable HWS. It describes traditional and future trends in urban water management, that is now guided by Water Sensitive Urban Design and Integrated Urban Water Management approaches. The technical aspects of HWS’, their components, benefits and drawbacks of their implementation are highlighted. Social implications from the viewpoints of water practitioners as well as consumers are discussed. An overview of the economics of hybrid water systems, both in terms of their cost and energy consumption per water unit is provided. Sections on the role of policy makers and governance arrangements for small-scale distributed water systems and an overview of the current status of rural and urban water trading schemes conclude the review.

The main aim of this review is to evaluate various biochar production methods, parameters affecting the production of biochar, facilities to investigate the composition and structure of biochar, mechanism associated with production of biochar as well as various modification procedures to suit biochar for different applications. Various methods used to synthesize biochar include pyrolysis, torrefaction, gasification, hydrothermal and flash carbonization. Several factors such as feedstock composition and type, pyrolysis conditions such as temperature and time strongly influences the property of synthesized biochar. The physico-chemical properties of biochar strongly influence the role of biochar in several applications such as fuel cells, biosorption, agriculture, supercapacitors, catalyst/support and environmental remediation. It was identified through research efforts that the properties of biochar can be altered using various chemical or physical agents to suit various applications. Thus, the present review consolidates recent advancements in biochar research with special attention towards contaminant remediation and agricultural applications.

One of these technologies, with high potential in wastewater treatment is the analysis of the particle size distribution (PSD) of contaminants. However, there are no detailed documented studies on the application of this technique. This study aimed at critically reviewing the technologies for PSD analysis and the application of chemical oxygen demand (COD) fractionation analysis for the characterisation of municipal wastewaters. The suitability of the PSD technology for wastewater depends on the type of wastewater and its treatment process applied. Despite the advancements in PSD technologies, many researchers and industrialists are yet to utilise PSD analysis for wastewater. It is possible to use PSD to map out the foulants distribution for optimal design of membrane treatment of municipal and other wastewaters. Biological processes increase colloidal particles which are predominantly responsible for membrane fouling. There should be more investigations on how different wastewater treatment processes alter the PSD of contaminants. More usage of PSD analysis will lead to faster and more optimal designs of the treatment processes for the removal of contaminants. It will also have great usage in the process design for the recovery of useful products from the wastewaters.

Although this control can be ensured through well designed joint treatment systems in cities, its application in rural areas is not as technically feasible. Therefore, the concept of decentralized treatment and source separation of domestic wastewater has been developed as a result of this requirement. This concept includes, not only control of nutrients, but also recovery and reuse of nutrients mainly for agricultural purposes. Among the source-separated fractions of domestic wastewaters, human urine or yellow water is of importance since it collects a significant part of all nutrients in a small volume. Therefore, studies have been focused on nutrient recovery from source separated human urine. This review evaluates the present state of urine treatment and resource recovery using struvite precipitation, ion exchange with zeolites and adsorption processes. The evaluation of these processes has been made by considering their theoretical bases, operational parameters, efficiencies, advantages and disadvantages. Coupling of these treatment and recovery processes with newly developed technologies such as electrochemical and biological means were considered. The impact of the use of these technologies on the environment was also evaluated. Further need of research for all processes has also been assessed and emphasized.

These membranes have negative or positive charged functional groups and can be named as cation- and anion-exchange membranes (CEM and AEM) depending on the sign of the permeating ions. As the electrical force is applied, the membranes allow the permeation of oppositely signed ions and separate the ionic species from an aqueous solution and from other uncharged species. Electromembrane processes are well-established techniques and have gained importance in many areas such as desalination processes, energy production, food processing, molecular separation, water treatment and recovery and membrane concentrate treatment. The desalination with electromembrane process is widely used today for the production of high-quality water from seawater or brackish water. The main electromembrane desalination processes are categorized as electrodialysis (ED), electrodeionization (EDI), capacitive deionization (CDI), reverse electrodialysis (EDR), electrodialysis with bipolar membranes (EDBM). In this review article, the most popular electromembrane desalination processes have been evaluated with their theoretical basis and technological background. The main objectives of the review are (1) to describe the technological background of electromembrane processes (2) to summarize past and present attempts towards scaling up and commercialization of electromembrane desalination process (3) to present a critical review of their advantages and limitations (4) to outline the R&D activities with cost analysis.
