Abstract
This study compares the functional and dimensional characteristics of the two drinking water treatment systems at Niamey's Goudel I and Goudel II plants. The results of this study show that the Goudel factory produced 36,089,492 m3 in 2018, corresponding to an annual production yield of 94.98%. The average specific electrical energy consumption of the Goudel factory is 537 Wh/m3. The average daily production at Goudel is 98,875 m3 /d for a theoretical nominal capacity of 85,000 m3 /d, which was increased to 110,000 m3 /d in 2013 following work to improve the factory's capacity. Production peaks in April with approximately 320,7757 m3 /month or 106925 m3 /day on a 30-day operating basis. The production trough was reached in February with approximately 2,725,551 m3 /month or 97,341 m3 /day based on 28 operating days. Electricity consumption reached 1,357,861 kWh, corresponding to a specific consumption of 498 Wh/m3. The plant's annual electricity consumption is 19,014,670 kWh. In 2018, 934,793 litres of diesel were consumed, compared with 1,079,659 litres in 2017, a saving of 144,866 litres equivalent to CFAF 77,937,908. Although sectors II and III use the same processes and the same production capacity, the Goudel 2 sector appears to consume the most energy.
