Aplicações de geotêxteis em estações de tratamento de esgoto de reatores uasb: um mapeamento sistemático da literatura

Abstract

The upflow anaerobic sludge blanket reactor (UASB) got several improvements, mostly since the 1990s, so that currently many Sewage Treatment Stations in Brazil use UASB reactors. These stations have some stages, such as pre and post treatment, along with the final disposal of the treated effluent. Among the most promising alternatives to improve these stages, the geosynthetics, especially the geotextiles, show a great potential due to their low cost and operational ease. In order to target the ways in which these polymers are being used in the context of the Sewage Treatment Stations, a systematic literature mapping was carried out to obtain articles within the scope. In this way, six different ways in which the material is being used were observed, with the vast majority having satisfactory results.
