Remote System For The Prevention and Control of Invasive Exotic Bivalves
Control of the Dreissena Polymorpha (Zebra Mussel)The selective, ecological and innocuous control of the zebra mussel is a challenge. This mollusk causes havoc wherever it is installed. Without enemies who can keep their expansion at bay, it dislodges other species and installs itself in structures that produce energy and irrigate our fields. Millions of hours of work have been spent by scientists from all the countries where D.P. is installed, in order to find an effective and environmentally compatible solution. Millions of euros or dollars, have been spent and still continue to spend, to the despair of those responsible. After many years of research and a lot of money invested, MARRONE BIO INNOVATION, has achieved a product capable of responding to this challenge. ZEQUANOX, is a product based on dead microorganisms. Pseudomonas fluorences is a bacterium that, ingested by the zebra mussel as food, causes its death. Its effect is lethal only to the zebra mussel. Other species feed on Zequanox without counterproductive effect. The water is not affected and after the application process the physical chemical conditions, they return to their original state. Is not it fantastic? |
Algae ControlEutrophication alters the environmental characteristics of aquatic ecosystems by altering the trophic chain and increasing the entropy (disorder) of the ecosystem. The result is ecosystems with reduced biodiversity, with opportunistic species occupying niches previously occupied by other species. The ecological consequences are evident but as they usually go hand in hand with economic losses for different reasons. Eutrophication occurs in several stages, which will be described below in grids.
Oligotrophic stage.This is the normal and healthy state of the ecosystem in it opportunistic and cosmopolitan species have a marginal space and there is a dynamic equilibrium with seasonal fluctuations. The water has a considerable transparency and there is an abundance of animals that breathe by filtering the oxygen of the water (fish, molluscs, aquatic arthropods). Contribution of nutrients, can be an episode or accident or continuous in time. It can be carried out in a punctual way (a discharge in a point of a river) or of diffuse form, with scattered origin (typical of the agricultural fertilizers). The contribution of nutrients causes an explosive growth of plants and algae. There are unicellular algae that grow in the water, in the photic zone of the same. Being photosynthetic algae give the water a greenish color that prevents the passage of light to depths previously reached. The vegetation below the new photic threshold dies, many of the floating algae also die and sink to the bottom due to nutrient depletion caused by exponential growth. The dead organic substance of the bottom is decomposed by bacteria that consume the oxygen and also can generate toxins lethal for plants and animals. The lack of oxygen causes bottom mollusks to die and fish and crustaceans die or escape to unaffected areas. Invasive species accustomed to oxygen shortage may appear (for example, barbs and perches may displace salmon and trout). In certain circumstances an anoxic zone (without oxygen) can be created in the bottom of difficult removal. It is more dense, dark and cold water in which neither algae nor animals can grow. |
Protection of structures of Irrigation SystemsUn sistema de riego es un complejo técnico compuesto de numerosos elementos destinados a captar, almacenar, transportar, impulsar, distribuir y dosificar el agua con fines agricolas.
Cada una de las fases del sistema de riego está expuesta, como consecuencia de sus funciones de uso y también por causas externas, a un desgaste de sus componentes Sin embargo exite un tipo de incidencia que es ajena a la propia vida util de los componentes. Se trata de fenómenos producidos por agentes orgánicos introducidos en el fluido y que producen grandes daños a estos sistemas. Algas, bacterias y otros microorganismos provocan incrustaciones, colmataciones, y incidentes que hacen reducir notablemente, no solo el rendimiento de los sistemas, sino que añaden costes por paradas y mantenimiento gravosos para los agricultores. Las especies exóticas invasoras acuáticas (bivalvos) introducidas en estos sistemas de riego a traves de acequias, canales y balsas, son en la actualidad el mayor problema con que nos enfrentamos. Como estan solucionando esto? El empleo de productos químicos, agresivos para los mecanismos y para la salud, es el método que se emplea habitualmente. Sin embargo, en la actualidad, ya existen en el mercado alternativas inofensivas para la salud y no agresivas para las estructuras. ECOWATER TECHNOLOGIES, dispone de estos avanzados tecnologicos que hacen reducir de forma drástica las incidencias en los sistemas de riego. ECOWATER TECHNOLOGIES, no basa su método en una sola aplicación. No existe un solo producto o equipo, capaz de resolver por si solo, la complejidad del problema. Años de trabajo y pesquisa han hecho que ECOWATER TECHNOLOGIES disponga de poderosas armas tecnológicas preventivas y de tratamiento,para resolver los problemas originados por la presencia de organismos que afectan los sistemas de riego. La combinación de tres procedimiento no quimicos en el conjunto del sistema de riego, protegerá las instalaciones en el conjunto del sistema y reducirá los costes de mantenimiento más de un 50%. |
