Abstract

In this paper, we present the design and evaluation of a prototype Autonomous Water Purifier (AWP) for removing heavy metals from contaminated water. The AWP prototype uses solar energy for its operation; the autonomous photovoltaic system is designed to operate up to 8 hours per day and to generate a water flow of 112 liters per day. The prototype was designed to remove biological and chemical agents. It was achieved the elimination of total coliforms, fecal coliforms, total alkalinity, total hardness, total solids, chloride and sulfate from 50 to 100%, as well as the removal of heavy metals. The Pb2+, Hg2+, Cd2+ and Cu2+ were eliminated from 80 to 99%. This wide range of contaminant removal shows a unique way to treat contaminated water in comparison to existing purification systems. The prototype was evaluated with river and spring water from different rural communities of Chiapas, Mexico. The results indicate that the prototype is able to completely remove contaminants in natural waters and get water that meets the guidelines that mark the Mexican official standards. This work helps to solve problems in marginalized communities and natural disaster areas where they have no access to clean water, electricity and suffer from waterborne diseases

社区规模自主净水器(AWP)原型机的开发，以去除重金属

在本文中，我们提出了一个原型自主净水器(AWP)的设计和评估，以去除污染水中的重金属。AWP原型机使用太阳能来运行;自主光伏系统被设计为每天运行8小时，每天产生112升的水流。原型机的设计目的是去除生物和化学制剂。总大肠菌群、粪便大肠菌群、总碱度、总硬度、总固形物、氯化物和硫酸盐的去除率达到50% ~ 100%，重金属的去除率达到100%。Pb2+、Hg2+、Cd2+和Cu2+的去除率为80% ~ 99%。与现有的净化系统相比，这种广泛的污染物去除显示了一种独特的方法来处理受污染的水。该原型用来自墨西哥恰帕斯州不同农村社区的河水和泉水进行了评估。结果表明，该原型能够完全去除天然水中的污染物，并获得符合墨西哥官方标准的水。这项工作有助于解决边缘化社区和自然灾害地区的问题，在这些地区，他们无法获得清洁水和电力，并遭受水传播疾病的折磨
