| 摘要 |
The present invention relates to a process for the selective removal of nitrates from ground water using a hybrid nanofiltration (NF) - reverse osmosis (RO) filtration system. The process generates product water that is low in nitrate and can be used for drinking, irrigation and other purposes, as well as waste water that is relatively low in salinity and can be safely discarded to sewage systems and recycled, e.g., for irrigation purposes. |
