Article
This research analyzes the water-energy nexus contribution to climate change from the integral water cycle perspective. A prior analysis of the sectors involved in global warming showed that clear water/energy interdependence was a crucial factor in increasing greenhouse gas (GHG) emissions. Although the analysis of water consumption in the energy...
Article
Because of their geographical isolation, many areas depend mainly on imported fossil fuels for their water and energy production. In this context, the Canary Islands are one such remote area. Due to the topography of the islands, there are numerous isolated areas on each of the islands far from the major population centres. These are known as ‘isla...
Article
This paper is a review of the history of desalination in the Canary Islands. There are many problems relating to the water supply in the Canary Islands, such as the scarcity of natural resources of drinking water, energy issues, dependency, and overexploitation. Some of these problems are common to many other areas in Europe. Technologies and innov...
Article
Nowadays, the most important problems that affect the world are carbon footprint decrease, fossil fuel use, and climate change. As proof of that, all environmental international agencies impose different laws and rules related to greenhouse effect. European Union policy is a clear example, which is explained in the document “2020 Strategies (COM/20...
Article
Recent studies and projects have shown that a combination of a reverse osmosis desalination plant with a wind power supply is technologically feasible if the plant operates with fluctuating and intermittent loads and in this way follows the variable energy supply characteristic of a wind turbine. The direct integration of renewable energy into a re...
Article
The reverse osmosis (RO) brackish water desalination plant described in this article has been operating without acid in the pretreatment and only using two types of antiscalants (this was the first experience of 40,000 operating hours in Canaries). This work describes the graphical evolution of all the daily operating information of the first five...
Article
This study proposes a simple design method of the Reverse osmosis (RO) system in RO brackish water desalination plants. This method is based on the application of maximum available recovery without scaling of any of the compounds present in the water as silica, calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, and calcium fluor...
Article
The purpose of this study is to undertake the characterisation of industrial-type wastewaters and to provide the design and application of a treatment system using membrane technology backed up by multiple laboratory-based experimental trials to observe and determine the stages required in the process. An analysis of the various industrial sectors...
Article
This paper presents the results of research work conducted as part of a doctoral thesis and undertaken with the aim of resolving the problem of accelerated fouling of reverse osmosis membranes (made from spiral-wound polyamide), as a result of the deposition of colloidal particles (particulate fouling), the precipitation of inorganic salts (scaling...
Article
This paper proposes a simple calculation method to estimate the maximum conversion level in reverse osmosis (RO) brackish water desalination plants. The method is based on the scaling potential of different compounds found in the water to be treated. These compounds include silica, calcium carbonate, calcium sulphate, barium sulphate, strontium sul...
Article

Semi-arid coastal zones often suffer water-stress, as water demand is high and markedly seasonal, due to agriculture and tourism. Driven by scarcity of surface water, the communities in semi-arid coastal regions turn to aquifers as prime water source; but intensive exploitation of coastal aquifers causes seawater intrusion, which degrades the quali...

RESUMEN: La desalación de agua de mar, por ósmosis inversa, representa una importante alternativa de abasto de agua potable, para la ciudad de Puerto Peñasco, Sonora México. Este proceso consiste en forzar la separación del agua de sus sales en membranas y la energía que consume es proporcional a la salinidad del agua y además requiere agua libre d...
Article
The paper presents the experimental results of several tests that have been carried out in a reverse osmosis plant powered by renewable energies. Mainly, the variations on feed flow, reject flow, recovery and power consumption are displayed as well as its relation with the available power. The plant studied has a production over 115m3/day at nomina...
Article
The direct integration of renewable energy into a reverse osmosis plant has been studied through this paper, as well as its relation with energy consumption, as a consequence of the plant working in variable loading conditions. The main objective is to display the adjustment of a reverse osmosis plant with a renewable energy source that is, without...
Article
Operation of an experimental RO plant connected directly to a wind system without energy storage was studied. The data obtained confirm the wide spectrum of operation of the plant with respect to the power available and the operation of the system.
Article
Brackish water or seawater desalination can be used to supply potable water in areas with scarce water resources. Brackish water of 1,000–10,000 ppm TDS can be desalinated at a significantly lower cost, i.e., about one-third of that of seawater, and requires lower energy input, an important consideration for areas with limited energy supply. Howeve...
Article
Following laboratory-scale research as part of the LIFE programme, a pilot plant with a capacity of 30 m 3 /d was built. This plant allowed the optimization of the parameters necessary for the engineering analysis, as well as the extrapolation of results and the development of a treatment plant with a capacity of 500 m 3 /d. The latter includes all...
Article
This article reports on the adverse effects on the microbiological quality of sea water with a high degree of biological contamination captured by an open intake system when it is subjected to intermittent, or shock treatment, doses of an oxidising biocide, such as sodium hypochlorite NaClO (KmnO4 O3, H2 O2), even though the purpose is to control m...
Article
This article reports the results of a process of optimising the dosage of Sodium hyplochlorite and Metabisulphite, performed on sea water in the pre-treatment division of the "Las Palmas III" reverse osmosis desalination plant, currently operated by Empresa Mixta de Aguas de las Palmas (EMALSA), responsible for providing drinking water to more than...
Article
It is hoped to make it sufficiently clear with this article that it is of fundamental importance that the reverse osmosis membranes and the conditions under which they will operate be appropriately selected. It is obvious that this choice must be made primarily in function of the quality of the water that will be processed in the water treatment pl...
Article
A study was carried out on a NaCl H2O RO thin film composite reverse osmosis membrane system to characterize these membranes, determine their performance and predict the effects of pressure and solute concentration in the feed using the correlation from the Kimura Sourirajan analysis. The effect of the solute concentration in the feed (0.0043–0.086...
Article
In the field of reverse osmosis (RO) there are several theories from which mathematical models have been developed, allowing for the simulation of processes and the prediction of results. This study used the model developed by Slater and Col, based on the solution-diffusion model for the simulation of RO processes. It was developed with an M20 RO L...
Article
The total production capacity of desalination plants in the Canary Islands is 212,000 m3/d. Brackish water plants, with 39,000 m3/d capacity, use membrane units of different sizes. Sea water plants include MSF, VC and RO units. Sizes range from small units for tourist resorts to large plants for urban water supply. New sea water plants, being built...
