Jinling Petrochemical's double-membrane device wastewater treatment reuse volume hits a new high

From January to June, Jinling Petrochemical continued to strengthen the management of energy conservation and emission reduction.
By implementing measures such as "micro-chemical cleaning", optimizing operating parameters, and eliminating equipment defects, the dual-membrane device for advanced wastewater treatment and reuse was kept stable and tall.

The company’s advanced wastewater treatment and reuse dual-membrane device is one of the key devices for water saving and emission reduction.
After the wastewater is pretreated, it undergoes advanced treatment through a multi-media filter, ultrafiltration + reverse osmosis double-membrane process, and produces The qualified water supply device is used as part of the raw material water supplement
.

Since the beginning of this year, plant management personnel have innovatively implemented the "micro-chemical cleaning" method through in-depth investigations, full analysis of water quality, simulation experiments and other methods.
Under the condition of ensuring the normal operation of the system, the membrane elements are cleaned and maintained in a non-stop cycle, and regularly Test the performance of the membrane system, adjust the concentration of the agent, and improve the operation cycle and efficiency of the device
.

At the same time, the equipment personnel delay the commissioning time of the spare unit exchanger according to the actual water tank level, and reduce the frequency of exchanger failure regeneration
.

Statistics show that in the first half of the year, the single-cycle operation time of the dual-membrane device was extended from 20 days to 125 days, and the load increased to about 480 tons per hour.
