Abstract
<MU><MU>"PROCESSO PARA REGULAGEM DE UMA INSTALAçãO FILTRANTE PARA LIMPEZA DE LìQUIDOS POLUìDOS"<MV><MV> e em especial líquidos poluídos com nitratos, como água poluída de origem industrial ou como água de solo, cuja instalação é feita principalmente de um barril do qual a parte de baixo tem uma parede que se afunila para baixo, que serve para colocação de uma camada filtrante de um material em forma de grãos, como por exemplo areia, com um cano em pé na camada filtrante para bombear, o qual contém um meio gasoso como ar, com um cano de entrada de ar regulável, com uma caixa de lavagem para a areia, sustentada pelo cano e posicionada acima da camada filtrante, e um sistema de canos até perto do fundo, para adição do líquido a ser filtrado e limpo, onde o fluxo de ar no cano de ar regulável esta regulado de tal maneira que sempre fique uma proporção constante entre o valor da resistência da camada filtrante real e o valor da resistência da camada filtrante desejada, onde o valor da resistência da camada filtrante desejada antes, está definido como a resistência de uma camada filtrante com um certo fluxo de alimentação.<MU> <MU> "PROCESS FOR REGULATING A FILTERING INSTALLATION FOR CLEANING POLLUTED LIQUIDS" <MV> <MV> and in particular liquids polluted with nitrates, such as polluted water of industrial origin or as soil water, which is installed mainly from a barrel from which the bottom has a wall that tapers downwards, which serves to place a filter layer of a material in the form of grains, such as sand, with a pipe standing on the filter layer to pump , which contains a gaseous medium like air, with an adjustable air inlet pipe, with a sand washing box, supported by the pipe and positioned above the filter layer, and a pipe system up to the bottom, for addition of the liquid to be filtered and cleaned, where the air flow in the adjustable air pipe is regulated in such a way that there is always a constant proportion between the resistance value of the real filter layer and the resistance value of the desired filter layer. where the resistance value of the desired filter layer is defined as the resistance of a filter layer with a certain feed flow.
