This paper studies how to increase the share of renewable energy by using solely stand-alone renewable energies to drive the water cycle. A case study is undertaken of El Hierro (Canary Islands, Spain), an island already on the path to becoming a 100% renewable energy island thanks principally to a wind-hydro power plant that covered around 60% of the annual electricity demand in 2018. The island's water cycle includes groundwater extraction, seawater desalination and water pumping and distribution, representing altogether around 35% of the annual electricity demand of the island. The idea is to investigate the possibility of driving the entire water cycle solely with the wind energy surplus. For this purpose, two scenarios are considered and developed: one based on the existing decentralised water cycle, and the second on an alternative centralised one, with just one modular reverse osmosis desalination plant and a centralised water storage system. The aim is to establish which model adapts best to an intermittent energy source such as wind energy without conventional backup systems. Results show that both scenarios lead to an increase in the overall renewable energy contribution in the island. Moreover, the centralised water model, specially due to its centralised water storage system, allows a higher contribution from renewable energy sources, increasing their overall annual penetration.

The water-energy nexus, together with the need for sustainable management of these interconnected resources, has attracted growing attention from the scientific community. This paper focuses on this nexus from the point of view of the energy that is required by wastewater treatment plants, which are intensive energy consumers and major emitters of greenhouse gases. The main objective of the study is to investigate the possible use of a wastewater plant’s internal chemical, potential, and kinetic energy, and the addition of external renewable technologies with a view to achieving clean energy consumption and reducing greenhouse gas emissions. For this purpose, an analysis is made of the feasibility of introducing alternative technologies—anaerobic digestion, hydraulic turbines, wind turbines, and photovoltaic modules— to meet the plant’s energy needs. The plant chosen as case study (Jinamar plant, Canary Islands, Spain) has an energy consumption of 2956 MWh/year, but the employed methodological framework is suitable for other plants in locations where the renewable energy potential has previously been analyzed. The results show that a renewable energy production of 3396 MWh/year can be obtained, more than enough to meet plant consumption, but also confirm the need for an energy storage system, due to seasonal variability in energy resource availability. In terms of climate change mitigation, the emission of 2754 tons/year of greenhouse gases is avoided. In addition, the economic viability of the proposed system is also confirmed.

Ultrafiltration (UF) membrane is an attractive pretreatment technology used in desalination water system. However, the unavoidable membrane fouling over time is the key problem in the development of this technology. Fouling evaluation in the initial stage may provide relevant information about the fouling tendencies. In this work, the extent of fouling was investigated through a new method allows evaluating the fouling in cross-flow UF in the initial filtration stage. An empirical adjustment of flux decline data based on a bi-exponential equation with 4 coefficients is proposed for determining the Rcfi and RV − CF parameters. The first parameter Rcfi is defined as the initial cross-flow resistance. The second parameter RV − CF is defined as increasing resistance per specific volume of permeate in cross-flow. The measurement of the fouling parameters is evaluated in a laboratory facility with the following established conditions: (1) operation in cross-flow mode and (2) a flow measurement period limited to roughly 1 h. The procedure is intended to detect two different flow decline zones with different fouling processes at the initial stage of cross-flow filtration. The method applicability was tested with two cellulosic membranes of 10 kDa and 20 kDa and solutions of 4 kDa and 35 kDa polyethylene glycol (PEG) and alginate at different concentrations. In the case of the Rcfi parameter, the results show measurable values with high colloidal concentration of PEG. The RV − CF results shows a sensitive increase with foulant concentration, in different degree, depending on the type of solution and membrane used.

This research analyses the feasibility of supplying the energy demand of a grid-connected large size desalination plant by wave energy. One drawback of the wave technology is that it is not yet fully commercial and, therefore, many different technologies are available. Different arrays of wave energy converters have been selected for this study, comprising different type of technologies and technical characteristics. Two scenarios have been deployed, one based on wave energy and another one that combines wave energy and solar photovoltaic energy. The hourly analysis shows the matching between demand and supply. The aim is to establish if solar photovoltaic energy can improve the hourly matching between demand and production. The methodology proposed has been applied to a practical case which is a 15,000 m3/day reverse osmosis desalination plant located in the North of Gran Canaria, whose annual energy demand is 19 GWh per year. Results show that most of the wave devices selected are able to meet the yearly energy demand of the desalination plant although there are significant differences depending on the wave technology and in the hourly analysis. The combination of photovoltaic and wave energy improves the hourly matching in some cases but not in all. Thus, an hourly analysis of the specific technology is needed in each case.

Much of the deterioration of water resources is anthropogenically caused as a consequence of the incessant production of chemical compounds to obtain the quality of life that society demands today. This constant presence and harmful accumulation of these pollutants in different ecosystems have seen them emerge as a major concern both for human health and for environmental safety. Scientific advances have succeeded in legislating against, reducing and even eliminating priority pollutants, while new technologies are being constantly developed to identify and treat newly emerging pollutants. The objective of this work is the evaluation of the seawater reverse osmosis membrane as a method for the removal of an antibiotic present in seawater. The novelty of the study is that the tests were undertaken using water of high ionic strength. A critical selection of the antibiotic to be used in the study was carried out. The experiments were performed under constant pressure conditions, employing synthetic seawater in a pilot-scale unit with a commercial spiral-wound reverse osmosis membrane. Results are shown in terms of selectivity of the reverse osmosis process for antibiotic removal. The RO membrane element successfully reject most of the ciprofloxacin (removal rate >90%), with maximum rejection value of 99.96%.
