Abstract

See full text

A system, that may be portable, for purifying liquid flowing gravitationally from a source/reservoir into a purified liquid receptacle is described. The system includes a housing with a generally horizontal filtering space. More than one liquid inlet disposed at a top portion of the filter is provided as well as one or more liquid outlets disposed at a bottom portion. The liquid flows in a generally lateral direction through the liquid treatment medium. Two or more first walls extending upwardly into the filtering space from a bottom wall thereof and ending with an apex are provided inside the device. One or more second walls downwardly extending into the filtering space from a top wall thereof are also provided. Each of the walls defines a closed path. The first and second walls jointly cause the liquid to flow in a curvilinear flow path from the inlet to the outlet. Apexes of the first walls may be defined such that each apex more distal along the liquid flow path is at a lower level than an apex of a first wall more proximal along the flow path. One or more venting ports may be formed at a top wall portion of the housing for releasing gas from the filter.
