• Abstract

  With increasing environmental concern regarding the urban impacts on global warming besides the scarcity of fossil fuels, biofuels are rising as promising renewable energy sources. In this scenario, the microalgae have advantage because they use CO2 as a carbon source, and they can be grown in the sewage or even in some industrial wastewater. This project aim to evaluate an efficient sequ…

• Abstract

  Given the severe impairment of water quality of surface water sources, especially regarding the concentration of dissolved organic matter and algae, dissolved air flotation (DAF) have been increasingly used in drinking water treatment due to better performance of this technique compared to conventional systems. The new third generation of DAF system is more compact and capable of operatin…

• Abstract

  The dissolved air flotation ( DAF) as a technique for high-efficiency pre - clarified water supply has been established for decades. Consequently there is a growing number of treatment stations being built in large scale worldwide. According to Schofield (2001 ) , at the beginning of the last decade there were several FAD units around the globe. This demand by DAF occurs as the dissolved …
