- Abstract:
- The design scale of phase I water purification plant of PADMA water supply project in Bangladesh is 45×104 m3/d. The raw water is characterized by high turbidity, large fluctuation of water quality and high sediment content. In addition, average turbidity of the product water is required to be less than 1.0 NTU, and the maximum turbidity does not exceed 5.0 NTU. High efficiency clarifier and V-type filter, the core water treatment process of Degremont Company, was selected in the design. Operation of the high efficiency clarifier is flexible and reliable. It has strong adaptability to the change of turbidity, and can automatically adjust the dosage of the reagent according to the change of water quality and quantity. The project has successfully passed the completion acceptance in 2019, and the water plant has been operating stably for nearly 2 years. The product water quality is better than the Bangladesh drinking water standard and the World Health Organization (WHO) drinking water quality standard, and turbidity of the product water is no more than 0.2 NTU.
