Abstract: The water treatment system and method incorporating the use of a hydrodynamic separator to remove most of the total suspended solids (TSS) in source water being treated to thereby lighten the load on membrane filtration in the water treatment system and lower energy costs.

Abstract: A non-filtration pre-separation device and method for the removal of algae using the same, comprising a system having a hydrodynamic separator including at least one curved structure for the removal of bio-organisms from seawater, such structure having an inlet in operative connection with a source of raw seawater and a bifurcated outlet operative for passing pre-treated effluent fluid to a downstream filtration system and the removal of waste fluid. Various fluidic structures, implementations and selected fabrication techniques to realize such a device, whether singular or in stacked and/or packed parallel configuration are also provided.

Abstract: 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.
