| titleOfInvention | COMBINED MEMBRANE TECHNOLOGIES FOR THE REMOVAL OF GRIND METALS FROM RESIDUAL WATERS FROM THE FIELD INDUSTRY |
| abstract | The invention relates to a process for the removal of chromium, zinc and nickel from waste water from the leather industry. According to the invention, the process consists in the chemical treatment of waste water in a microfiltration membrane equipped installation, passing the permeate through a membrane with reverse osmosis at 2 bar, the resulting solution being subjected to membrane separation in the emulsion obtained from a mixture of emulsifiers tensides in the class of the amyphiphiles, and a classical tenside at a ratio of 1: 1: 1 and a concentration of 0.5-3%, for heavy metals using a specific complex, such as a quaternary ammonium salt, when there are obtained two phases, a heavy-metal emulsion-type membrane phase, and a purified residual water phase. |
