- Abstract:
- In order to save energy of the 60×104 m3/d pressurized ultrafiltration membrane system in Beibu Waterworks of Guangzhou, the energy consumption control was researched. The results showed that the lifting pumps to feed the ultrafiltration membrane process have the highest operating energy consumption among all the equipments in the system, accounting for 76.02% of the total energy consumption. By optimizing the process control program, the setting operation mode of the inlet main header pressure of the ultrafiltration membrane stack and the instantaneous flow of the lift pump were changed into the automatic adjustment operation mode, which resulted in the operating energy consumption of the lift pump to drop by 18.75%, the total energy consumption of the ultrafiltration membrane system to drop by 19.00% simultaneously, and the average specific energy consumption to drop from 0.046 79 kW·h/m3 to 0.037 9 kW·h/m3, realizing a more economical, intelligent and refined operation of the ultrafiltration membrane process.
