The invention concerns a water treatment method which consists in introducing coagulated water in a flocculation zone, to enable flocculation of microflocs in the presence and around a ballast; introducing the mixture in a decantation zone; separating the treated water in overflow and a mixture of sludge and the ballast in underflow; conveying at least part of said mixture to a sludge/ballast separating system and recycling into or upstream of the flocculation zone the ballast and part of the sludge introduced in said separation system. The invention is characterized in that it comprises steps which consists in conveying the mixture to the sludge/ballast separating system; in subjecting said mixture to a ballast concentration, extracting the ballast from the sludge extracted from the separation system; and more than 20% of the volume entering the sludge/ballast separating system is recycled into or upstream of the flocculation zone, after passing through at least part of the sludge/ballast separation system; and the ballast has an effective diameter greater than 60 micrometers, and the sludge extracted from the treatment system has a concentration higher than 5 g/L.

A phosphorus removal system is operable to remove phosphorus from an influent. The system includes a first section receiving the influent and discharging a first flow. A first coagulant inlet is positioned upstream of the first section and is in fluid communication with the influent to introduce a first coagulant selected to precipitate phosphorus. A second section receives the first flow and discharges a second flow, and a third section receives the second flow and discharges an effluent. A second coagulant inlet is positioned downstream of the first section and upstream of the third section to introduce a second coagulant selected to precipitate phosphorus.

A method of cleaning a membrane surface immersed in a liquid medium with a fluid flow, including the steps of providing a randomly generated intermittent or pulsed fluid flow along the membrane surface to dislodge fouling materials therefrom. A membrane module is also disclosed comprising a plurality of porous membranes () or a set of membrane modules () and a device () for providing a generally randomly generated, pulsed fluid flow such that, in use, said fluid flow moves past the surfaces of said membranes () to dislodge fouling materials therefrom.
