A roll ultrafiltration module comprises a central tube with radial holes, around which one or more membrane packages are spirally wound, which consist of two membranes with a grid-turbulator placed between them and separated from each other by a drainage sheet. On the grid-turbulator an impermeable partition is applied, with initial coordinate, which coincides with location of the impermeable partition in the central tube and is determined by the dependence.where- height of the flow channel, m;- number of discharged liquid in m/h;- amount of supplied liquid in m/h;- width of the end of discharge channel, m;- width of the beginning of flow channel, m;- width of the central tube, m,and end coordinates of impenetrable partition on the grid-turbulator, which have the following values depending on the mode of operation;;;;where L - length of the membrane. |
