The following study of the head loss in filters, whether of upstream or downstream flow, is of main importance in the projection and mainly in the operational control of such units in a water treatment plant (WTP). However, ...

With the frequent difficulty both due to lack of water availability and quality, new treatment technologies aimed at ensuring water quality in supply and better use of water resources have been the target of research and ...

Pre-filtration followed by slow filtration is highlighted by its ability to promote greater efficiency in removing variable physical characteristics from raw water. The study aimed to apply different filtration rates to ...

Removal of oocysts in drinking water has on granular bed filtration, with previous coagulation and with or without sedimentation an efficient barrier for Cryptosporidium control. USA regulation for Cryptosporidium control ...

The decrease of physicochemical and microbiological quality of surface supply source for human consumption, requires specific complementary treatments to ensure the supply of safe drinking water. This study evaluated the ...

Changes in the quality of surface water sources have been recurrent in developing countries due to their accelerated urbanization processes. In this sense, it is essential that water treatment plants (WTPs) in these ...

Atrazine is one of the most often used herbicides in the world. It reaches the surface water body by runoff, direct application or airborne dispersal. Conventional water treatment methods do not efficiently remove these ...

The present study was conducted to determine if TRPC6 regulates glomerular filtration rate (GFR) and the contractile function of glomerular mesangial cells (MCs). GFR was assessed in conscious TRPC6 wild type and knockout ...

Compreender e quantificar os mecanismos relacionados à perda de carga e à remoção de partículas em um meio filtrante granular é de importância fundamental para o estudo do processo da filtração. Este trabalho apresenta o ...
