Abstract: A process for treating waste waters with TDS?20 g/l, possibly containing organic substances, includes the following steps: a. separating the saline wastewater or waste waters from suspended solids and heavy pollutants by physical separation, forming a saline stream free of suspended solids and heavy pollutants; b. subjecting the saline stream to reverse electro-dialysis, using a reservoir solution to reduce the saline concentration and forming a diluate and a diluted stream (waste water) with TDS not higher than 20 g/l; and c. biologically treating the diluted stream obtained in (b) forming biological sludge, or excess sludge, and clarified water.

Abstract: An acid gas absorbing mixture and a process for the removal of acid gases from gaseous mixtures containing them, such as natural gas, air and flue gases and an absorbent mixture usable for the removal of acid gases from gaseous mixtures containing them includes at least one diol of general formula R(OH)2 having a normal boiling point equal to or greater than 100° C.; at least one organic base having a pKb (in water) lower than or equal to 3; and a polar aprotic solvent having a dielectric constant F at 25° C. greater than or equal to 30, a viscosity p at 25° C. lower than or equal to 40 cP (centipoise). The organic base/diol weight ratio is lower than or equal to 0.6, and the aprotic solvent/diol weight ratio is between 0.05 and 0.6.

Abstract: There is a method for extracting bio-oil from algal biomass, in particular oily microalgae, using solvents of a Deep Eutectic Solvents (DES) capable of producing a bio-oil with a low content of phospholipids and inorganic salts, mainly sodium chloride.
