Freshwater is crucial for human well-being and sustainable socio-economic development. Worldwide, an estimated 748 million people remain without access to an improved source of drinking water, and water demand for manufacturing is expected to increase by 400 percent between 2000 and 2050, globally. About 2.5 billion people remain without access to improved sanitation, especially in Sub-Saharan countries. A large quantity of water is wasted as wastewater, arising from several activities, such as industrial and agricultural activities. Environmental pollution, arising from the discharge of untreated wastewater, is increasing, and the quest for finding different water and wastewater treatment methods is highly encouraged, especially for developing countries and for areas which lack community piped drinking water and sufficient energy supply. Therefore, this Special Issue seeks to highlight new studies and research highlighting recent advancements with regard to water and wastewater treatment and re-use.
Potential topics include, but are not limited to:
- New techniques for water and wastewater treatment
- Methods for water analysis and water quality monitoring
- Development of different materials for water and wastewater treatment
- Application of nanotechnology in wastewater treatment process
- Description of water utilities in developing countries
- Case studies for the application of adsorption process for real wastewater treatment:
- Optimization of the treatment process
- Production of biofilters
- Reuse of treated water and its environmental impact
- Contaminants in water and wastewater
- Biological wastewater treatment:
- Zero liquid discharge
- Brine treatment

Abstract: Water scarcity and water pollution is a concerning problem worldwide and has driven research into eco-friendly and low-energy cost efficient remediation, intending to the reuse of wastewater for non potable purpose, after proper treatment. Advanced Oxidation Processes (AOPs) based on the in-situ generation of hydroxyl radicals have been intensively investigated for this purpose. Hydroxyl radicals generated by AOP, follow unselective multi-step pathways which limit their efficiency in complex environmental matrices. To overcome such limitations, AOP treatment based on generation of sulfate radicals have been developed and widely investigated. This current review study will cover the most recent developments regarding emerging contaminants removal using sulfate radicals generated by activated persulfate or peroxymonosulfate, with focus on on application to wastewater effluents for possible wastewater reuse.

Abstract: As climate becomes more unpredictable and water-related extremes such as floods and droughts are intensified, water management and infrastructure developments are intensively challenged. Municipal infrastructure technologies and designs are long-term investments and capital projects that cannot be quickly replaced or adapted and may not only be inadequate for handling increased intensity, duration and frequency of water-related climate extremes but actively erode community resiliency to those extremes. Results from interview and survey methods in rural agriculturally-driven communities indicate that respondents are significantly more concerned about infrastructure capacity and response to flood conditions (78%) than drought. Not only are infrastructure technologies more vulnerable to performance and capacity impacts of excessive water, but the communities relying on those infrastructures for protection, control, and mitigation of extreme water events are similarly increasingly vulnerable. The results of this research indicate impacts not only on the physical infrastructure of communities, but the social fabric and community resiliency in response to flood and drought.

Abstract: Arsenic contamination of groundwaters is one of the major human health threats that humanity is facing. Treatment of arsenic usually involves oxidation and then removal by coagulation with iron or aluminium salts or adsorption. This is because conventional treatment methods do not remove efficiently the trivalent arsenic from water. Therefore, in this work, we examined several pre-polymerized coagulants of iron and aluminium for As(V) and As(III) removal under various conditions in order to investigate the efficiency of these materials for removing both species of arsenic without the need for pre-oxidation. From all coagulants tested, including the conventional ferric chloride, only poly ferric sulphate (PFS) was able to remove arsenic(III) to concentrations below 10 μg/L. With a s dose of 5 mg/L of PFS, treatment of water containing 25 μg/L As(V) and As(III) respectively, resulted in water with less than 5 μg/L arsenic, without the need of any additional treatment. Use of conventional coagulants could not achieve similar results.

Abstract: This study aims to review the technological innovations applied for the treatment of leachate. The review shows that both biological and physical-chemical treatments are not able when applied in single treatment to achieve the requested quality level for treated leachate, according to the limits established by regulations for the discharge into the sewer system or into surface water. One of the few exceptions can be reverse osmosis, as it is able to remove most of the pollutants reaching almost the highest percentages compared to other single treatments, and because it achieves such results for any type of young, medium or old leachate. In order to respect the current limits fixed by regulations, the construction of depuration systems combining biological chemical-physical treatment methods is considered of utmost importance, because each of them can contribute to depuration in different ways.
Title: Efficiency of iron-based oxy-hydroxides in removing antimony from groundwaters to levels below the drinking water regulation limit

Abstract: Τhis study evaluates the efficiency of iron-based oxy-hydroxides to remove common antimony from groundwaters at the requirements of drinking water regulation limit. Results obtained by batch adsorption experiments and rapid small-scale column tests indicate that iron oxy-hydroxides designed to maintain a high positively charge density, achieve residual concentration of Sb(III) below 5 μg/L, by providing an adsorption capacity of 3 mg/g. This is more than double compared to similar commercial Fe or binary Fe/Mn adsorbents. Considering the rapid kinetic of the process and the compliance to the leaching test regulations, the developed adsorbents may be promoted as possible materials for water treatment at the household level for application at vulnerable communities.

Abstract: Cr(VI) is a very toxic and carcinogenic element, which is widely present in groundwaters, mainly due to geogenic conditions. The limit of Cr(VI) in drinking water is expected to be reduced to 10 μg/L in both USA and the European Union. Cr(VI) removal by conventional methods has been proved inefficient in reducing Cr(VI) levels to below 10 μg/L, unless reduction of Cr(VI) by Fe(II) or other reducing agents is used. In the present study, we investigated the use of a novel treatment method for Cr(VI) removal comprised by Fe(II) dosing, pipe flocculation enhancing Cr(VI) reduction to Cr(III) and removal of particles by microfiltration. One part of the filtered solids is recirculated into the pipes, where flocculation takes place. This provided additional solid surfaces and enabled the reduction of Cr(VI) with less amount of Fe(II), as in conventional Fe(II) reduction treatment systems. The results showed that water containing 300 μg/L of Cr(VI) could be efficiently treated with 1 mg/L of Fe(II), with a ratio of around 3:1 at pH 7. Final Cr(VI) and total chromium concentrations were below 10 μg/L. Fouling of membrane did not take place even after one year of operation.

Abstract: The use of Fe(II) for the reductive removal of Cr(VI) from groundwaters is well demonstrated. Fe(II) reacts with Cr(VI) and the result is the formation of Fe(III) hydroxides and reduction of Cr(VI) to Cr(III). Cr(III) is then either precipitated as Cr(III) hydroxides or is adsorbed in iron hydroxides and is removed from water through filtration. However, until to date the role of natural organic matter in the water has rarely been investigated and is not sufficiently understood As a result the required treatment for Cr(VI) from groundwaters in waterworks is a delicate task to be realized, especially if very low concentration (< 10 µg/L) in product waters are envisaged. The present paper will give insides on fundamental mechanisms in Cr(VI) removal under varying pH, dosages of Fe(II) coagulants and content of natural organic matter. Kinetic issues will be matter of investigation as well.
