Abstract
Provided concerns a device for treating water of the kind intended for treating running water from a domestic water supply system or other sources of pressurized water, to obtain filtered or treated water, for example, of drinking water quality.
Claims15
A water treatment device for treating running water from a pressurized water source, comprising a housing with a running water inlet and a treated water outlet, the housing defining:
- two or more cylindrical water treatment compartments, each having a longitudinal axis and having a water compartment inlet and a water compartment outlet, the treatment compartments being arranged in parallel one to the other;
- a water inlet-manifold having an inlet-manifold ingress in liquid communication with said running water inlet, and at least two inlet-manifold egresses, each of the egresses being in liquid communication with one of the water compartment inlets;
- a water outlet-manifold having an outlet-manifold egress in liquid communication with the treated water outlet, and at least two outlet-manifold ingresses, each of the ingresses being in liquid communication with the water compartment outlets;
- each of the two or more water treatment compartments comprising treatment media that comprises:
- a first water treatment medium in the form of a tubular porous block made of a first composition and having a tubular block diameter, and formed about an axial lumen having a lumen diameter, the ratio between the block diameter and the lumen diameter being between 1.5 and 2, and
- a second water treatment medium enveloping the first water treatment medium, the second water treatment media being in the form of a pleated fibrous sheet;
- in each of the two or more water treatment compartments, the water compartment inlet feeds water into a space formed between the second water treatment medium and an internal face of the compartment, such that the water flows (i) radially through the second water treatment medium, then (ii) radially through the first water treatment medium and into the axial lumen.

- a second water treatment medium enveloping the first water treatment medium, the second water treatment media being in the form of a pleated fibrous sheet, and
- a third water treatment medium that comprises polyphosphate and positioned within the axial lumen, such that the axial lumen envelops said third water treatment medium;
- in each of the two or more water treatment compartments, the water compartment inlet feeds water into a space formed between the second water treatment medium and an internal face of the compartment, such that the water flows (i) radially through the second water treatment medium, then (ii) radially through the first water treatment medium and into the axial lumen, and then (iii) through the third water treatment medium positioned within the axial lumen.
