Análise da viabilidade técnica da utilização de lodo de estação de tratamento de água na produção de corpos cerâmicos

Abstract

The problem of water shortage has worsened every decade in the world. The amount of usable water in the world is little and poorly distributed. Part of the Middle East, Africa and Central America are already lacking water, and this scenario is making desalination of seawater something increasingly attractive, especially for the regions mentioned. However, desalination of sea water also has its obstacles. The processes for desalinating water are also generators of waste. The water treatment plants generate enormous amounts of sludge, being necessary to seek alternatives for reusing these wastes in order to not harm the environment. This research aims to analyze alternatives of seawater desalination in the world, discoursing about the use of their main residue and verify, by experimental way, the feasibility of using this waste in the ceramic industry
