Aquadaf - Clarify surface water with a simplified engineered integration

  1. 1. Aquadaf ™ (RICTOR process) SURFACE WATER CLARIFICATION THROUGH DRINKING RAPID FLOTATION WITH HYDRAULIC WATER FLOCCULATOR CLARIFY SURFACE WATER WITH A SIMPLIFIED ENGINEERED INTEGRATIONP-PPT-EP-008-EN-1004 1
  2. 2. DRINKING CONTENTSWATER Aquadaf™ Aquadaf™ in the fast Flotation Range Aquadaf™ in the Drinking Water Offer Background of Aquadaf™ Operating Principle Advantages of Aquadaf™ Among our References Case Study: Macao MSR, CHINA 2 2
  3. 3. DRINKINGWATER FAST FLOTATION RANGE Aquadaf™ As part of the line of rapid flotation solutions, the Aquadaf™ is designed for clarification of surface, borehole or river water. Two types of flocculators are available: a mechanical version (MF model) or a hydraulic one (HF model). RESOURCE PRODUCT NAME PURPOSE Borehole, river Aquadaf™ Drinking Water Surface water Seawater Seadaf™ Purification before DMF Environmental Treated wastewater Greendaf™ * Discharge Biofilter Backwash Wastewater or water Greendaf™ * Environmental Discharge *Greendaf™ product is declined into 2 sub-products 3 3
  4. 4. DRINKING Aquadaf ™IN THE DRINKING WATER OFFERWATER Aquadaf™ Aquadaf™ enhances the Degrémont product line for clarification of surface water. It is unique in its versatility and fast performance during the flotation phase. Its greatest advantage is its ease of operation. Coagulation Settling Media Filtration Raw Water Polishing Disinfection Distribution Flocculation Flotation (Sand – GAC) Raw Water Reagent-free Membrane Filtration Disinfection Distribution Coagulation Raw Water Membrane Filtration Disinfection Distribution flocculation 4 4
  5. 5. BACKGROUND OF THE Aquadaf™ c p AquaDAF™ Rictor (2002) Time coagulation flocculation = 2 + 12 minc p Degrémont 1st adaptation (2006): Aquadaf™ MF (Mecanical Flocculation) Time coagulation flocculation = 2 + 10 min Degrémont 2nd adaptation (2007): Aquadaf™ HF (Hydraulic Flocculation) Time coagulation flocculation = 3 + 5 min 5 5
  6. 6. Aquadaf™ HF: OPERATING PRINCIPLE1. COAGULATION 2. Hydraulic FLOCULATION 3. SATURATIONFerric chloride or alum. Used to create micro flocs. 8-10% recirculation,Coagulation Time Flocculation Time = 5 min pressurization et and= 1 + 2 min release assembly. Raw Water Treated Water 5. PERFORATED FLOOR 4. FLOTATION Patented Technology. Formation of bubble Velocity 20-40 m/h blanket in flotation zone. 6 6
  7. 7. DRINKING ADVANTAGES OF Aquadaf™ (1/2)WATER Aquadaf™Aquadaf™ is versatile:• It treats even very cold surface-water (as low as 0°C),• It supports occasional peaks in SS or turbidity up to 200 NTU.Aquadaf™ is competitive: Flash Mixer Hydraulic Flocculator Flotation Unit• Its new design for the flocculation phase: reduces minimum reaction time to 5 min, allows for a smaller facility footprint while maintaining performance, adapts to various water types with its 2 stages of flash mixing and 4 potential reagent injection sites. 7 7
  8. 8. DRINKING ADVANTAGES OF Aquadaf™ (2/2) WATER Aquadaf™Aquadaf™ is easy to operate:• Easy maintenance (few mechanical parts, no lamellar modules),• No need for materials to ballast the flocs,• No constraints relating to Flash Mixer Hydraulic Flocculator Flotation Unit complicated flocculant application (polymers),• No major risks associated with defects or missing polymers. 8 8
