Abstract:
Objective To investigate the effect of liquid temperature, pressure, concentration, pH parameters on the membrane process and rejection in the process of using reverse osmosis membrane to concentrate oil-bearing water bodies ultrafiltrate of Compound Chuanxiong Capsules, and optimize the process. Methods With oil-bearing water bodies ultrafiltrate of Compound Chuanxiong Capsules volatile oil as the research object, the changes in flux under different operating parameters was measured. Results For this system, suitable operation parameters was as follows: pressure was 1.6 MPa, temperature was 35～ 40 ℃, pH was 9～10. Conclusion Using reverse osmosis membrane to concentrate oil-bearing water bodies ultrafiltrate of Compound Chuanxiong Capsules volatile oil, better flux and rejection can be obtained at the appropriate operating conditions.
