A company's aeration transformation plan of the sewage plant in Chengdu
Product performance + quick construction = winner
Overview of the sewage plant
The plant is the industrial sewage treatment plant, with a daily sewage treatment capacity of 150,000t.
GSD undertakes transformation of aeration basins.
Fan power required by every two groups of aeration basins before the replacement is 183.3KW.
Fan power required by every two groups of aeration basins after the replacement is 165.8KW.
Energy conservation comparison calculation:
Every two groups before the replacement:
Monthly electric charge: 183.3kw.h×24h×30 days× RMB 0.8= RMB 105,580
Annual electric charge: RMB 105,580 ×12= RMB 1,266,960
Every two groups after the replacement:
Monthly electric charge: 165.8kw.h×24h×30 days× RMB 0.8= RMB 95,501
Annual electric charge: RMB 95,501 ×12= RMB 1,146,012
Annual cost savings for every two groups: RMB 1,266,960-RMB 1,146,012 =RMB 120,948
Annual electric charge savings of the plant: RMB 120,948 × 7 / 2 = RMB 423,318
