A water filtration module () is made of hollow fibers for filtration from the outside to the inside of the fibers, wherein the fibers are arranged inside a casing () made of multiple elements (). The module () and at least one element () include elements working together, which are designed to enable the element () to be mounted in the module () in a removable manner.

Water filtration module and method for the manufacture and use thereof

A module for ultrafiltration or microfiltration of water includes hollow fibers, of the type of filtration from outside inwards of the fibers, the water to be treated being introduced at the top of the module and the treated water being collected at the bottom of the module. The fibers are arranged inside a housing in multiple U-shaped bundles, the module being vertically arranged in use with the U-shape in the top part of the module. At the bottom of the module, each bundle is arranged in a sheath and individually potted. The sheaths are then urged to be housed in a distribution plate, and all the sheaths are interconnected by pouring (in reverse vertical position relative to that of the filtering mode) a potting resin.

Water filtering module with hollow fibers

The invention concerns a method for membrane filtering of water, characterized in that the filtering through membranes is performed by using as differential pressure source the water level in the tank wherein the membranes are immersed, and the membranes are of the fiber type with outer skin, substantially arranged in a U-shape and potted in their low section.

Method and device for membrane filtering of water

The invention concerns a water treatment method and installation, which consist in subjecting the water to be treated to membrane filtration ( ) to satisfy the requirement for a relatively high flowrate of water for ordinary use (UF), subjecting the water that has been subjected to membrane filtering to reverse osmosis filtering ( ) to satisfy the requirement for a smaller flowrate of water of improved quality (OS) and, outside periods of production of water filtered by reverse osmosis, sweeping the upstream face of the osmosis membrane ( ) with the flow of membrane-filtered water drawn off to be consumed.
