| 摘要 |
The invention relates to devices for carrying out processes of membrane separation of solutions and suspensions and can be used for treating sewage waters, cleaning potable water form underground and surface water sources and for concentrating solutions in the chemical, food and other industries. Said invention makes it possible to increase the performance and service life of a membrane apparatus. The inventive membrane device comprises connected by pipelines an initial solution container (1), an injection pump (2), a pumped-hydrostorage reservoir (3), a membrane apparatus (4), a regeneration unit (5) provided with a recirculation line and a range of shut-off-and-regulating valves. The novelty of the invention lies in that the inventive device is additionally provided with a bactericide filter (6) arranged upstream of the initial solution container, a pressure controller (7) disposed between the pumped-hydrostorage reservoir and the membrane apparatus, an additional pump (8) mounted on the pipeline for discharging a permeate. In addition, the body of the membrane apparatus comprises a carbon fibre layer which is impregnated with an epoxide resin and arranged on the external side thereof and the regeneration unit of the membrane element is provided with a vibrator placed on the end surface of the membrane apparatus body on the side of the permeate discharge. |
