For the industry brine denitrification process can only work in the status quo of light brine (NaCl concentration ≤ 200g/L), in order to solve the demand of sodium sulfate removal in the high salt system (NaCl concentration ≥ 290g/L), our company has developed the unique and original "FTM-High Salt Brine Denitrification Technology", which is a technological process using the nanofiltration film rolled up in depth customized by our company and the international famous membrane manufacturers, and it can be Long-term stable operation between NaCl concentration 290~305g/L, sodium sulfate removal rate can reach more than 98.5%. And can maintain a stable retention rate for a long time.

Technological Advantages：

1. Good concentration

Based on the material properties of the customized nanofiltration membrane sheet, it is possible to concentrate sodium sulfate up to 80 g/L in high salt systems.

2. Operational stability

Based on our mature process design, multiple protections are used to prevent damage to the nanofiltration membrane element or abnormal performance decay during normal operation. Greatly extend the service life of nanofiltration membrane. Existing performance has maintained stable operation for more than six years.

3. Good retention effect

Guaranteed low nitrate water sulfate below 1.5 g/l (initially below 0.5 g/l) during its three-year life cycle. The system has a certain retention of aluminum, iron and silicon ions.

4. Convenient operation

High degree of integration and automation of the device, the site only needs to be on duty personnel to regularly patrol, saving labor.
