Transcript

  • 1. Cleargreen™ BIOLOGICAL TREATMENT OF EFFLUENTS WITH HIGH CONCENTRATIONS OF AMMONIA URBAN WASTEWATER ELIMINATE NITROGEN CAUSED BY ANAEROBIC EN-1004 DIGESTION OF SLUDGEP-PPT-ER-009-E 1
  • 2. UrbanWastewaterW t t CONTENTS Cleargreen™  Why a new product to treat ammonia?  Cleargreen™ in the treatment line  Operating Principle  Advantages of Cleargreen™  Case study: Creil-Montataire (60), FRANCE 2 2
  • 3. Urban WHY A NEW PRODUCT TO TREATWastewaterW t t AMMONIA? Cleargreen™  Nitrogen treatment requires high operating costs• Nitrogen removal needs 2 successives biological reactions (nitrification and denitrification) requiring high levels of : 1-Energy consumption for aeration 2-External carbon (ex. : méthanol) ( )• The growing market for anaerobic sludge digestion and biogaz reuse leads to : A 15% to 35 % (in case of co-digestion) increase in nitrogen load to be treated on the water treatment line.This treatmnt increase energy and external carbon consumption and could also increase volumes. 3 3
  • 4. Cleargreen™ IN THE TREATMENT LINE * **Ultrafor™, Biofor™, Cyclor™ or Meteor™ 4 4
  • 5. UrbanWastewaterW t t OPERATING PRINCIPLE (1/2) ( ) Cleargreen™ • A biological treatment which is based on the Anammox bacteria ti b t i action i a SBR in SBR. • A reactor equipped with captors, continually monitoring the system to limit human intervention. • An implemented biological reaction of deammonification. p g  A process divided into 4 stages into one tank 5 5
  • 6. UrbanWastewaterW t t OPERATING PRINCIPLE (2/2) ( ) Cleargreen™ Specific features: p Cleargreen™ specifically treats the concentrated flow of nitrates: it does not return to the head of the water treatment line. Field of application for urban WWTP: – Retun flow from digested (Digelis &Digelis Turbo) sludge dewatering, – Centralized sludge treatment plants –L Leachate h t 6 6
  • 7. UrbanWastewaterW t t ADVANTAGES OF Cleargreen™ g Cleargreen™ • A patented, innovative, award-winning process award winning • Ease of operation: – Spontaneous installation (without seeding) of the specific biomass due to the control of the process’ conditions – Automatic control of cycles and regulation – Simple interface for an optimized management of aeration – Low-maintenance • Performance: – Robust adaptability to variations in load and effluent composition • Sustainable Development: – No reactive agents needed – Preservation of energy resources • Savings: – Automatic regulation of air supply (= control of consumption) 7 7
