Effect of Oil and HPAM in Polymer Flooding Wastewater on the Desalination Process by Electrodialysis
A lab-made static electrodialysis (ED) unit was used to study the effect of oil and HPAM on the desalination process by electrodialysis. To do so, various kinds of wastewater samples were prepared to simulate the polymer flooding saltwater treated by ultrafiltration. The demineralization process and the fouling of the ion-exchange membranes could be studied by comparing the removal rates of salt by the desalination processes under different experimental conditions. Results showed that effect of oil on the desalination processes by electrodialysis was quite minor, while the polymer in simulated saltwater has much more effect on the desalination process, indicating serious fouling of ion-exchange membranes caused by HPAM.
