COMBINED SEWER

A sewer system that carries both sewage Colloids represents mixtures of particles that are capable of remaining evenly distributed throughout a solution. As colloids disperse, the substances remain separated but do not reach the bottom of the container. While the substance is dispersed, it is alluded to being in the dispersed phase, while the substance that it is dispersed in is referred to being in the continuous phase. In order to be labelled as a colloid, the substance must be larger than a molecule size but small enough not to be seen by the naked eye. If the dimensions of the colloid is lesser than the range of 1 and 1000 nanometers then it is categorized as a solution, and if they are larger than the substance is referred to as a suspension.
