Abstract: The invention relates to a water treatment line and a process for removing suspended solids, such as ferrous scale, and in particular also oils and greases, from cooling waters of metallurgical or steel processing. A sedimentation tank is included in which there is a lamellar pack filter with inclined sedimentation surfaces comprising a plurality of adjacent, essentially parallel and inclined tubular profiles, in particular with an angle of inclination with respect to the bottom of said tank of 50-65°. The application of the laminar packs in the tank which separate suspended solids, in particular ferrous scale, by sedimentation avoids the use of sand filters or the like.

Abstract: A method of providing water suitable for irrigation use includes feeding pre-treated water to an electrodialysis apparatus, treating the pre-treated water in the electrodialysis apparatus by selectively removing either one or both of monovalent anionic and monovalent cationic species from the pre-treated water while retaining either one or both of multivalent anionic and multivalent cationic species to produce a treated water stream having a lower ratio of monovalent ions to multivalent ions than the pre-treated water, and directing the treated water into an irrigation water distribution system.
