    Water Scarcity and the Construction Industry: Implementation of Alternative Sources of Drinking Water for Civil Works
    (2023-12-19) Bonell, Valentina; Canova, Eliana Evelyn
    Abstract— This article focuses on the importance of using potable water, a limited and essential resource, in the production of concrete in the construction industry. It is also highlighted that the use of non-potable water in the production of concrete is inefficient. Additionally, it explores various innovative solutions to obtain drinking water that does not depend on conventional water sources. These solutions include desalination, transforming wastewater into drinking water, rainwater harvesting, and modifying concrete mixes to make them less sensitive to the type of water used. It is expected that this work can generate a significant impact on readers and encourage the adoption and promotion or alternative ways of generating safe water for civil works.

    Lack of Sanitation: Algae Ponds for Wastewater Treatment in Remote and Rural Areas
    (2023-12-19) Ibarra, Bruno; Acosta, Ramiro
    Abstract— Millions of people around the world do not have decent access to sanitation to meet their basic hygiene and health needs, leading to disease and thousands of deaths per year. The objective of this work is to address wastewater treatment for domestic or agriculture uses and sanitation installations in rural areas so that the inhabitants of these communities have a better quality of life. To achieve this aim, this work addresses the problem, causes and consequences of lack of sanitation in rural and remote areas of cities. Secondly, a system of algae ponds to treat wastewater will be presented. Finally, an analysis is made of the benefits and disadvantages that may arise from the proposed solution. It is expected that this paper may promote the implementation of alternative and sustainable methods for wastewater treatment.

    Industrial Wastewater Treatment: Efficient Management and Reuse by means of Batch Recirculation Electrocoagulation
    (2023-12-19) Moya, Natanael; Ríos Balsells, Nicolás
    Abstract—In the last few decades the exponential urban growth and the development of new technologies have been demanding more resources from the earth. The minerals extraction and the following production processes that are part of the elaboration chains have been contaminating the air with emission gases, as well as the soil and especially bodies of water with dangerous chemicals. In this paper, the water treatment processes are approached with the purpose of providing information about the different methods and solutions to treat wastewater effectively and efficiently. Therefore, an innovative treatment, the batch recirculation electrocoagulation (BRE) process, for certain kinds of wastewater which are difficult to clean, is presented and analyzed in terms of cost-effectiveness, efficiency, and efficacy. It is expected that this work might help other researchers to do their investigations by giving more information about the wastewater issue. Thus, there will be more contributions and further research about green alternatives to combat wastewater contamination consequences.

    Sustainable water consumption: Options for grey water filtration systems for homes
    (2023-11-15) Baudino, Lucio; Pross, Luisina
    Abstract— Water is one of the most important resources for the existence of life on our planet and to keep it. Nowadays, this resource is in danger due to the careless use that it has been given over the years, growing demand and climate change. For these reasons, several countries in the world have serious water crises or they are on the way to having them. One way to fight against the water crisis is the recovery of otherwise discarded water through greywater treatments. The aim of this paper is to delve into the technologies available today to realize greywater treatments at homes anywhere. In this paper, different types of filter systems which use physical and chemical methods will be presented. In addition, it will show advantages and disadvantages of each treatment system and their application in homes.

    Lack of clean water access in rural schools in Northern Argentina: Air humidity water collection and dust filtration technology to obtain clean water
    (2023-11-15) Cornet, Tiago; Strack Garcilazo, Juan Pablo
    Abstract— The water scarcity problem is critical in rural schools in northern Argentina, where geographical challenges, limited financial resources and alternative water sources contribute to the lack of water access. The United Nations’ Sustainable Development Goals #4 and #6 encompass the problem stated in this paper, and it is a central problem to the 2030 Agenda. Once the drivers of the problem are understood two options will be presented to obtain clean water: Fresh Water Ecco System and the P&G Purifier Packets. Finally, pros and cons of each innovation will be discussed. It is expected that this work might provide insight into this topic that needs urgent attention, and also raise awareness about deficiencies that there exist in some parts of Argentina, and how these affect the education and social development of the inhabitants.
