Excessive input of nutrients (fertilizers, detergents, wastewater,...) EUTROPHICATION
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
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
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

DUMO Algacleaner on freshwater ecosystems
•Helps to restore natural dynamic balance between:– Input nutrients–Algal biomass•Kills algae.•Migitates algal growth.
DUMO Algacleaner on freshwater ecosystems
•DUMO Algacleaner can reduce algal biomass in 42 days.•Effects become evident in two weeks.
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)
DUMO Algacleaner benefits
