- Abstract:
- The siphon submerged ultrafiltration membrane process with the capacity of 2×104 m3/d was adopted to reconstruct the original sand filter with the capacity of 1×104 m3/d in Luoqiao waterworks. The system has operated well, with large membrane flux and high interception accuracy. At the designing water yield of 2×104 m3/d, the transmembrane pressure was 5 kPa and the membrane flux was 35 L/(m2·h). At the peak-hours water yield of 3×104 m3/d, the membrane flux was 50.4 L/(m2·h), and the transmembrane pressure was 10 kPa. The water recovery exceeded 96%. The system produced water using the method of siphon in low liquid level, without additional land occupation and water pump. The system had run stably with low energy consumption and operating costs.
