- Abstract:
- The application of a village-level waterworks in Guangdong Province using gravity flow and low flux ultrafiltration process system based on Internet of Things (IoT) is introduced. The characteristics of process design and IoT platform are summarized, the effluent quality and operating cost of the waterworks are analyzed, and the overall operation effect of the system is evaluated. The results show that gravity flow and low flux ultrafiltration process could effectively cope with the high turbidity in water source when treating surface mountain stream water, and the effluent quality could meet the Standards for Drinking Water Quality (GB 5749-2022) steadily. The effluent turbidity is less than 0.1 NTU, and microbial indicators of the effluent are far superior to the standard requirements. The application of the IoT supervision platform could realize unattended operation and remote control of the waterworks, which improve the level of operation and maintenance. The long?term operation of the waterworks is steady, membrane fouling rate is relatively low, and the chemical cleaning cycle could be extended to 3-5 months, which reduce the cleaning frequency and maintenance costs. The process design with no external power greatly reduces the energy consumption, and the direct operating cost of the waterworks is only 0.058 yuan/m3. The gravity flow and low flux ultrafiltration process system based on IoT can effectively ensure water quality safety, and realize the simplification and optimization of water purification system for easy operation and maintenance, which is of great significance to the water supply in mountainous rural areas.
