Abstract
A modular filter assembly for cleaning and polishing of potable waters including a fabric turbidity removal module and an adsorptive taste and odor removal module. The modules are connected in series so as to have turbidity removal prior to taste and odor removal to extend the operating life of the taste and odor removal module. The turbidity removal module includes a porous, fabric material assembly which is of a rolled or wrapped construction which provides a large filtration area to prevent its clogging prior to the utilization of the adsorptive capabilities of the taste and odor removal module. The turbidity removal module includes a flow grid assembly having inner and outer flow grid to maximize the distribution of the fluid being filtered over the filtration area of the module and to assure lateral flow of the filtered fluid through the module. The modular construction enables the turbidity removal module to be utilized separately and renders the module self-cleaning when operated under certain flow conditions. The taste and odor removal module is provided with flow dispersion means which serves to reduce the flow velocity of the filtering fluid through the module to prevent …
