Abstract

Technologies to be applied under the context of protection and revitalization of surface water must be developed and improved in order to enhance the quality of aquatic ecosystems. In this way, this study aimed to evaluate the treatment performance of an inverse margin filtration system (IMF) applied in surface water treatment. The IMF was monitored during 1 year through the classic water quality parameters, and thus the treatment performance along the filtration path was identified. The results showed an average removal efficiency of 41% for turbidity, 35% for apparent color, 43% for true color, 26% for total suspended solids and total organic carbon, 53% for nitrogen, 46% for phosphorus, 91% for iron, 8% for manganese, and 100% for fecal coliforms. In this way, the IMF system proved to be a technology that can be applied in the treatment of water in lentic environments.

Highlights

In tropical countries, water bodies such as rivers, lakes and seas have always had multiple functions, acting as means of transport, in the production of food, and as a direct source for public supply (Walsh, 2000)
A very important characteristic of the groundwater level position is that the configuration varies according to the season, due to the recharge of groundwater, which is the addition of water above the surface of the saturated zone, and is related to the quantity and precipitation distribution (Arantes, 2003)

Summary

Introduction

Water bodies such as rivers, lakes and seas have always had multiple functions, acting as means of transport, in the production of food, and as a direct source for public supply (Walsh, 2000). The urbanization and the development of cities are increasingly prevalent in these places. This dynamic makes it difficult to manage water resources, mainly due to the demand for water, both in terms of quantity and quality (Shamsuddin et al, 2014). The RF has been showing positive results regarding water treatment. In some places, such as America, this technique is used as a preliminary treatment of water, while in the Europe, for example, this technology is used as the sole treatment of water supply public, plus chlorination only (Grünheid et al, 2005)
