Abstract: A control method and system for controlling the operation of a seawater injection system comprising at least one water treatment line in which seawater is forced through one or more coarse filtration unit(s), ultrafiltration unit(s) and at least one of a reverse osmosis unit and/or a nanofiltration unit to a water injection pump, and wherein the flowrate required to create differential pressure across membrane(s) of the ultrafiltration unit(s) is obtained by a boosting pump. A controller “C” implemented operation control is applied to adjust automatically the outlet pressure and flow of the boosting pump such that an average flowrate through the ultrafiltration units is maintained and determined as boosting pump flow divided by the number of active ultrafiltration units. A proportional-integral-derivative control mechanism is preferably applied to all adjustable flow/pressure regulating units in the seawater injection system.

Abstract: Method of recovering iron and/or phosphorus from sludge of waste water treatment plants, said sludge being obtained after precipitation by iron salts, wherein said method comprises separating sludge from waste water and submitting said sludge to a lactic fermentation to release a liquid phase where iron and phosphorus are dissolved. Lactic fermentation is performed with addition of a co-substrate rich in carbon, preferably rich in carbohydrate, in one single step of biological acidification or a sequencing biological acidification in two steps by first releasing phosphorus from the PAO contained in the sludge. Iron can then be recovered by means of a cationic exchange resin. Phosphorus can be recovered as struvite or calcium phosphate from the remaining solution substantially free from iron ions, after a precipitation step in presence of a magnesium or calcium source and a pH above 7.
