DUMO Algacleaner - Ultrasonic treatment and ecosystems

  1. 1. Ultrasonic treatment & ecosystems
  2. 2. Public parks Solar thermal plants Irrigation ponds Ornamental lakes • Large variety of ecosystems –Shape –Size –Construction –Use... Freshwater ecosystems
  3. 3. Freshwater ecosystem proper operation ALGAE Chlorophyll “a” Animal biomass: Zooplancton Fishes …. O2 Nutrients N and P Nutrients input Light Sun (Energy ) - All components are connected - Natural balance - “Alive” dynamic systems
  4. 4. Freshwater ecosystem improper operation ALGAE Chlorophyll “a” Animal biomass: Zooplancton Fishes …. O2 Nutrients N and P Light Sun (Energy) Excessive input of nutrients (fertilizers, detergents, wastewater,...) EUTROPHICATION
  5. 5. Freshwater ecosystem improper operation ALGAE BLOOM !!!  Turbidity increases  Oxygen decreases  Anaerobic process: malodorous gases  Accumulation of reduced substances (sulphides, ammonium, Fe, Mg...) DECREASING WATER QUALITY: Loss of natural balance between input nutrients and algae
  6. 6. Algal bloom Relationship between nutrients and the algal community weight: 1P: 7N: 40C: 100 g dry weight: 500 g wet weight (Vallentyne, 1978) 1 gram of phosphorus can produce up 500 grams of algal biomass
  7. 7. Solutions against eutrophication CURATIVE MEASURES Anti-algae chemicals with immediate action Short-term treatment TEMPORAL EFFECTS PREVENTIVE MEASURES (Water quality improving) Medium/long-term treatment PERMANENT EFFECTS MORE EFFICIENT
  8. 8. Solutions against eutrophication PREVENTIVE MEASURES (Water quality improving) Medium/long-term treatment PERMANENT EFFECTS MORE EFFICIENT Ultrasonic treatment against algae
  9. 9. DUMO Algacleaner on freshwater ecosystems • Helps to restore natural dynamic balance between: –Input nutrients –Algal biomass • Kills algae. • Migitates algal growth.
  10. 10. DUMO Algacleaner on freshwater ecosystems • DUMO Algacleaner can reduce algal biomass in 42 days. Ultrasonic treatment with DUMO Algacleaner in an irrigation pond with wastewater input. Cyanophyte Mycrocistis aeruginosa bloom. Test carried out by the Experimental Centre of New Technologies of Water (CENTA) in 2014 (www.centa.es)
