Roll-type nanofiltration membrane concentration scheme
Thread Content
A sugar factory needs 300 T of sugar solution to be concentrated daily, with a concentration of 5%. The results of the field experiment showed that after membrane concentration, the concentration of the concentrated solution was 10%, with a stable flux of 300 ml/min. The experimental temperature ranged from 40 to 60°C, and the operating pressure was between 2.5 and 3.5 MPa. It is known that the customer requires 22 hours to complete the process, and the area of the experimental membrane is 1.8 m2. I would like to ask the experts: what size should a circulation pump be? How should it be arranged properly? What size should the pipe be? Are there any calculation methods or companies for these?
The process conditions in question are completely unacceptable – 60 degrees is too high; there are very few membranes that can be used continuously at such temperatures. The concentration of substances like xylose that I work with is carried out at temperatures below 35 degrees. I hope this reminder will be useful to you
