In this paper the electrolytic process application as a water purification treatment stage from the Ipe neighborhood lake (Ilha Solteira - Sao Paulo, Brazil-) was evaluated. The treatment efficiency for apparent and true ...

The aim of this research was to determine the efficiency of activated carbon obtained from coconut (Cocos nucifera) endocarp in the reduction of color in runoff water to improve its quality. For this purpose, activated ...

In this research the color removal through electrolytic process, followed by direct filtration with six different doses of Al-2(SO4)(3) for the Parana river potabilization in Ilha Solteira-Sao Paulo was evaluated. The ...

Azo dyes are a class of dye most used industrially, being also some of the main contaminants of industrial effluents. Among these, the dye yellow dye is an azo dye highly used in the food industry and must be efficiently ...

Acrylic resins have been widely used due to their acceptable esthetics and desirable characteristics such as easy handling, good thermal conductivity, low permeability to oral fluids and color stability. Flexible resins ...

The dyeing process in textile industries generate effluents with high levels of coloration and difficult degradation, becoming a menace to the environment where it is discarded, In the treatment of these waste, the color ...

Sometimes it is said that white is not a color but “the sum of all colors.” Surely this confusion comes from considering colors only those that appear in the spectrum. If these were the only colors, then magenta would ...

En el presente trabajo se estudió la oxidación química con permanganato de potasio y un oxidante a base de manganato de nombre comercial manhídrox, del lixiviado tratado previamente en un reactor biológico anaerobio de ...
