“…Its main advantage is that they allow obtaining high quality water and can be applied to the community supply as they can produce large volumes of water. Some examples of SSS based on ultrafiltration which have been implemented successfully at commercial level are: Aquapot [16], Aqualogix® [17], SkyHydrant®, AquaBoy® and SkyStation® [18] or Mobil watermaker [19].…”

a b s t r a c tDrinking water must be colorless, odorless and tasteless, and free of substances or micro-organisms that can cause disease. The process to obtain drinking water is purification, understood as the treatment to make water suitable for human consumption. Water purification is traditionally composed of a sequence of standard treatments including coagulation-flocculation, sedimentation, filtration, and disinfection. Some compounds named coagulants are used for coagulation-flocculation, which is the stage in which the suspended matter is removed and the water is clarified. Coagulants are usually synthetic, therefore represent a high cost and are difficult to gets in some areas, especially in developing countries. In addition, their use is being revised and restricted in different international standards, in order to control or prohibit its use because of the possible hazard effects that the remains of these products in treated water can cause to people. In contrast to synthetic coagulants, there are several natural compounds with coagulation properties which have some advantages such as easy availability and safety. At present, scientific community is paying more attention to natural coagulants as legal restrictions to synthetic ones are becoming more severe. This paper is a review of natural coagulants as an alternative to chemical coagulants, in which their potential application in the treatment of drinking water is analysed.

“…Some examples of UF-based SSSs that have been successfully tested are the AQUAPOT system [3], Aqualogix® (made by Garrow Ltd.), SkyHydrant® [24], AquaBoy®, SkyStation® [22] and Mobil watermaker [25]. These systems differ in terms of production, water quality, pretreatment and post-treatment, costs and energy requirements.…”

Access to drinking water is a basic human right which has become an international goal. However, despite the efforts made in the framework of the Millennium Development Goals of the United Nations, about 700 million people are still without access to an adequate source of drinking water in rural areas of developing countries, especially in Africa Sub-Saharan. The AQUAPOT project, developed by the "Instituto Universitario de Seguridad, Radiofísica y Medioambiental (ISIRYM)" of the "Universitat Politècnica de València (UPV)", both in Spain, has been focused research on the design, development and installation of decentralised drinking water systems as an alternative to existing water management systems in developing areas. AQUAPOT systems are based on ultrafiltration technology and have been successfully applied in different localities in Ecuador and Mozambique to produce safe drinking water for human consumption. The present paper describes the main actions carried out within the project AQUAPOT over the last 20 years. It describes the main features of the installed plants and the protocol to choose the best location; it also shows the main results achieved within the project, and discusses the lessons learned throughout the years in relation to the operation of the plants as well as the quality of the treated water.

several misprints remained in the text. The correct text reads as follows: Page 954, Column 2, Equations (4) and (6) For the reader's convenience, we take this opportunity to correct Equations (4) to (6): V Fe3O4 À V consumed Fe ¼ N h À 1 ð Þ 4 3 p R 3 0 À R 3 À Á (4) where R (m) is the radius of the consumed iron particle and h the coefficient of volumetric expansion. The proportion of consumed iron (% consumed Fe) is given by: % consumed Fe ¼ 100 R 3 0 ÀR 3 R 3 0 (5) It is possible to determine the proportion of consumed iron when the volume of the iron corrosion product without the volume of the consumed Fe (V Fe3O4-V consumed Fe) is equal to the initial porosity F 0 (m 3) according to: % consumed Fe V Fe3O4 À V consumed Fe ¼ F0 ð Þ ¼ 100 F 0 N hÀ1 ð Þ 4 3 p R 3 0 (6)
