Pulsazur - Eliminate organic matter and micropollutants with low operating costs

  1. 1. Pulsazur™ POWDERED ACTIVATED CARBON CONTACTOR DRINKING WATER ELIMINATE ORGANIC MATTER AND MICRO-P-PPT-EP-011-EN-1004 POLLUTANTS WITH LOW OPERATING COSTS
  2. 2. DRINKING CONTENTSWATER Pulsazur™ Pulsazur™ Product Using Pulsazur™ Features specific to the process Pulsazur™ as part of a treatment line Advantages of Pulsazur™ Case Study: Apremont (85), FRANCE Case Study: Gorron (53), FRANCE 2
  3. 3. DRINKING WATER Pulsazur™ PRODUCT Pulsazur™ • Pulsazur™is a new process that uses adsorption over powdered activated carbon (PAC) in a sludge blanket reactor. • Pulsazur™is used to treat water that contains a high level of dissolved matter after suspended solids have been reduced. • Pulsazur™is used to obtain water of a constant quality from a variable raw water throughput and quality with a minimum flow >50% of nominal flow. Treated waterPre-clarified water PAC + Coagulant 3
  4. 4. DRINKINGWATER USING Pulsazur™ Pulsazur™ • Pulsazur™ is a structure that forms part of a conventional or membrane potable water treatment line • Pulsazur™ is used during the polishing treatment stage for adsorption of: – Micro-pollutants (pesticides, molecules responsible for taste and odors) – Dissolved organic matter (TOC >10 mg/L) • Pulsazur™ is positioned downstream from pre-clarification and upstream from the sand filter: – For optimum adsorption, it is advisable to reduce suspended solids – Filtration through sand constitutes a safety barrier as it screens out solid particles (PAC leaking out with the coagulant) 4
  5. 5. DRINKINGWATER FEATURES SPECIFIC TO Pulsazur™ Pulsazur™ • The quality of the treated water depends on the resistance of the PAC bed and on the PAC selected – PAC bed resistance demands: • A maximum sedimentation rate of 4m/hour • A 2.60 m deep PAC bed – The PAC selected is the NORIT SA Super 5
  6. 6. Pulsazur™ AS PART OF A TREATMENT LINEAs part of a conventional line, Pulsazur™ is used to produce water of a constant quality. Chlorine PAC Pre-clarified water (by sedimentation or Refined water floatation) Coagulant Pulsazur™ Aquazur™ PAC reactor Sand filtrationAs part of a membrane line, the Pulsazur™ contributes to the production of good qualitywater from poor resources. Chlorine Backflush water Refined water Coagulant PAC PAC Pre-clarified water (by sedimentation or floatation) Coagulant Pulsazur™ Aquazur™ Ultrazur™ PAC reactor Sand filtration Ultrafiltration 6
  7. 7. Pulsazur™ ADVANTAGES• A PROVEN TECHNOLOGY – Pulsed bed clarification, a reliable technology found in applications throughout the world• CONTROLLED HYDRAULICS ENSURING THAT THE PAC BED IS MAINTAINED AND THAT THE RATE THROUGH THE APPLIANCE REMAINS STEADY• A FLEXIBLE OPERATION THAT COPES WITH CHANGES IN FLOW OR QUALITY – By adjusting pulse and sludge extraction frequency and duration• OPTIMUM USE OF POWDERED ACTIVATED CARBON WHICH IS KEPT HOMOGENOUS BY THE INCOMING PULSED FLOW• EASY MAINTENANCE – No submerged units, no abrasion or corrosion possible 7
