  • 1. 1 DRINKING WATER Ultrazur™ ZW1000 INTEGRATE A “BACTERIOLOGICAL BARRIER” FROM THE CLARIFICATION PHASE ADVANCED CLARIFICATION WITH IMMERSED ULTRAFILTRATION MEMBRANES P-PPT-EP-010-EN-1004
  • 2. 2 DRINKING WATER 2 CONTENTS Ultrazur™ ZW1000 Ultrazur™ ZW1000 in the Ultrafiltration Range Ultrazur™ ZW1000 in the Treatment Lines Ultrazur™ ZW1000 Systems Features of the Systems Key Points of Operating Principle Advantages of Ultrazur™ ZW1000 Case Study: Macao MSR, CHINA
  • 3. 3 DRINKING WATER 3 ULTRAFILTRATION RANGE As part of the ultrafiltration line solutions (filtration systems using ultrafiltration membranes) solutions, Ultrazur™™™™ is designed for drinking water production. Ultrazur™ ZW1000 Borehole, river Surface water Seawater Treated water RESOURCE PURPOSE Ultrazur™ Ultramarine™ Ultrablue™ PRODUCT NAME Drinking Water Purification before Reverse Osmosis Reuse Ultrazur™ ZW1000 is the model described in this presentation.
  • 4. 4 DRINKING WATER 4 Flotation Coagulant Chlorination Ultrafiltration Ultrazur™ZW1000 Settling Coagulant Chlorination Ultrafiltration Ultrazur™ ZW1000 Ultrazur™ ZW1000 IN THE TREATMENT LINES • Ultrazur™ ZW1000 makes up part of an advanced clarification system. • The out-in filtration / immersed membrane technology requiring coagulant injection is positioned after flotation or settling to filter out particles as small as 0.02 µm in size. Ultrazur™ ZW1000
  • 5. 55 4 PROCESS TRAIN 3 CASSETTE2 MODULE1 MEMBRANE Ultrazur™ ZW1000 SYSTEMS Raw water Ultrafiltered water
  • 6. 66 Ultrazur™ ZW1000 SYSTEM FEATURES • A system made up of cassettes in series immersed in a concrete gravity-feed tank • 4 cassettes models available all using the same-sized modules • 2 different module densities offering either 46.5 m² or 55.7 m² filtering surface area • Selection of module type depends on water quality at the ultrafiltration tank inlet 500 ft² Module 600 ft² Module
  • 7. 77 KEY POINTS OF OPERATING PRINCIPLE • Out-in filtration • Gravity-feed tanks • Common peripheral water and air feed piping for all tanks Feedwater Ultrafiltered water Optional recycling at plant inlet Backwashing water Distribution Buffer tank Chlorination Filtration Backwash Air
  • 8. 8 DRINKING WATER 8 Ultrazur™ ZW1000 ADVANTAGES CONSISTENT QUALITY OF TREATED WATER • Turbidity < 0.1 NTU • Bacterial abatement – >4 log for cysts and bacteria – >4 log for viruses CONSTRUCTION • Compact design for easy set-up • Simple integration with existing systems OPERATION • Automated operation • Possible increase in membrane surface area in the event of degradation of feedwater quality Ultrazur™ ZW1000
  • 9. 99 CASE STUDY: MACAO, CHINA CONTEXT: • Client: SAAM (Sociedade de Abastecimento de Águas de Macau) [SUEZ ENVIRONNEMENT] • Date of work: Sept. 2006 – May 2008 • Challenge: limited space, turbidity, algae content • 2-phase project: 2 x 60 000 m3/day DESIGN : • Capacity phase 1: 60 000 m 3 /day net Number of Ultrazur™ ZW1000: – 5 lines of 3 cassettes with 90 modules each (+ 6 dummy modules) o 60,619 m² of filtering surface area • Treatment line: – Flotation with Aquadaf™, Ultrafiltration.
