Iranian Scientists Utilize Nanomembranes to Purify Wastewater of Olive Oil Plants

Tehran, Iran | Posted on August 20th, 2015

The researchers introduced a special arrangement of synthetic nanomembranes as the best system to obtain the highest efficiency in the purification process and to reduce the costs.

Studies on purification of olive oil wastewater showed that membrane processes have the highest efficiency while their operational cost is reasonable. Therefore, various types of ultrafiltration with nanometric pores and nanofiltration membranes have been produced in this research, and they have been compared to the existing commercial samples in the field of olive oil purification process. The aim of the study was to find the best membrane to decrease the contamination as much as possible.

According to the research, the membrane purification system with a consistent arrangement is better than other methods reported in the previous researches to purity olive oil wastewater. The unique arrangement proposed in this research has two stages of nanofiltration, and it is able to purify olive oil wastewater at very high efficiency. In general, the results showed significant decrease in the amount of pollution based on the environmental standards.

Using nanofiltration membranes decreases the operational pressure in the final purification stage in comparison with reverse osmosis process. This fact has numerous positive effects by decreasing operational and investment costs.

Results of the research have been published in Desalination and Water Treatment, vol. 53, issue 5, 2015, pp. 1254-1262.
