Abstract

Изобретение относится к устройству и способу очистки бытовой сточной воды. В частности, изобретение относится к очистке в домашних условиях бытовой сточной воды, образующейся из водных растворов после стирки и/или полоскания белья, с целью экономии воды за счет повторного использования. Неожиданно было обнаружено, что можно разработать устройство и способ, в которых с помощью непрерывного продувания воздуха, разрушения пены и сепарации вода после стирки и полоскания белья может стать, по существу, не содержащей поверхностно-активных веществ. Затем эту воду предпочтительно фильтруют для получения отфильтрованной воды, которую можно повторно использовать во множестве применений.
