Abstract

The invention relates to a method for removing marine larvae from zooplankton, regarded as an underwater pest found floating in the sea and in bodies of salt water, or adhered to a surface. For this purpose, the water is passed through a duct in order to be collected in a pond or it is handled in the open sea. An initial count of the marine organisms is performed, after which a device emitting ultrasonic waves is used to eliminate said organisms, and subsequently another count is carried out in order to compare the results. The final count is taken when the method is performed and again several days later. The data are compiled manually or through a photographic record, and then stored and processed in an electronic device.

Description

MEMORIA DESCRIPTIVA  DESCRIPTIVE MEMORY

Un método para la eliminación de larvas marinas componentes del zooplancton que comprende una fase preliminar de recuento de larvas seguido de la aplicación de ultrasonido para eliminarlas y posteriormente otro recuento de larvas sobrevivientes siendo los datos obtenidos procesados estadísticamente A method for the elimination of marine larvae components of the zooplankton comprising a preliminary phase of larval counting followed by the application of ultrasound to eliminate them and subsequently another count of surviving larvae being the data obtained statistically processed

Campo de la invención Field of the Invention

Existen diversos tipos de larvas marinas componentes del zooplancton que constituyen plagas submarinas que se encuentran en las aguas del mar y en cursos de agua salada que entorpecen actividades de producción, de refrigeración, de acuicultura así como de almacenamiento o de transporte de agua. There are several types of marine larvae that are components of the zooplankton that constitute underwater pests that are found in sea waters and in saltwater courses that hinder production, refrigeration, aquaculture as well as storage or water transport activities.

Estas larvas marinas que constituyen plagas submarinas o bien se encuentran flotando y desplazándose en el líquido que los contiene, o bien se encuentran adheridas provisoriamente o definitivamente en superficies planas, curvas o con aristas. These marine larvae that constitute underwater pests are either floating and moving in the liquid that contains them, or they are temporarily or permanently attached to flat, curved or edged surfaces.

Es por ello que el método explicitado en esta Solicitud es de interés para varios sectores de actividades relacionadas con el agua de mar; como Plantas de producción de agua potable a partir de agua de mar por osmosis inversa, sistemas de refrigeración para centrales térmicas, centros de producción acuícolas y de producción de biodiesel que requieren de un gran flujo de agua de mar. That is why the method explained in this Application is of interest to several sectors of activities related to seawater; as Production plants for drinking water from seawater by reverse osmosis, cooling systems for thermal power plants, aquaculture production centers and biodiesel production that require a large flow of seawater.

HOJA DE REEMPLAZO (Regla 26) Diferentes medios son utilizados en la actualidad para eliminar estos animales. Entre ellos se puede mencionar la utilización de compuestos químicos que buscan o bien eliminar el organismo o desprenderlo de la superficie en la cual se encuentra adherido. Estos productos químicos suelen ser contaminantes para el agua y a veces pierden eficacia con el tiempo. REPLACEMENT SHEET (Rule 26) Different means are currently used to eliminate these animals. Among them we can mention the use of chemical compounds that seek to either eliminate the organism or detach it from the surface on which it is attached. These chemicals are often pollutants for water and sometimes lose effectiveness over time.

También se pueden filtrar con mallas y filtros muy finos, siempre y cuando el agua sea bombeada y transportada por ductos, sin embargo esta alternativa en general no es siempre aceptable por el alto costo que ella implica. Por último también pueden ser eliminados con elementos físicos como la luz ultravioleta germicida, pero las dosis de rayos ultravioletas requeridas implican equipos de alto costo e importante consumo de energía lo cual limita su utilización.  They can also be filtered with very fine meshes and filters, as long as the water is pumped and transported by pipelines, however this alternative in general is not always acceptable because of the high cost it implies. Finally, they can also be eliminated with physical elements such as germicidal ultraviolet light, but the doses of ultraviolet rays required involve high-cost equipment and significant energy consumption, which limits their use.

Han sido inventados numerosos instrumentos y equipos basados en principios ultrasónicos que abarcan prácticamente todos los ámbitos de interés humano, desde la medicina hasta la construcción de naves espaciales. Se comprobó que los haces ultrasónicos pueden servir para inspeccionar la presencia de fallas en el espesor de los materiales sólidos sin alterarlos en absoluto. Un tipo de aplicación en otro campo utiliza un haz ultrasónico totalmente distinto permite soldar materiales muy duros, o de modelarlos, dándoles formas muy complejas. Numerous instruments and equipment based on ultrasonic principles have been invented covering virtually all areas of human interest, from medicine to the construction of spacecraft. It was found that ultrasonic beams can be used to inspect the presence of faults in the thickness of solid materials without altering them at all. One type of application in another field uses a totally different ultrasonic beam allows welding very hard materials, or modeling them, giving them very complex shapes.

Descripción de la invención Description of the invention

Esta invención está destinada a resolver las dificultades que representan las larvas marinas al estar en el agua de mar e interferir con actividades productivas, acuícolas e instalaciones de almacenaje o equipos y artefactos destinados al transporte de agua de mar. This invention is intended to solve the difficulties that sea larvae represent when being in seawater and interfere with productive activities, aquaculture and storage facilities or equipment and artifacts intended for the transport of seawater.

Para ello, se utiliza un método no destructivo que no requiere contacto físico, aparte de la emisión de las ondas en el agua de mar que está focalizado en bloquear el metabolismo de las larvas marinas indeseables, impidiendo su proliferación y su asentamiento en una superficie. For this, a non-destructive method is used that does not require physical contact, apart from the emission of waves in seawater that is focused on blocking the metabolism of undesirable sea larvae, preventing their proliferation and settlement on a surface.

Adicionalmente se procede al inicio al recuento de la población de dichas larvas y a posteriori otro recuento que permite evaluar los resultados y, más adelante, después de unos días medir el nivel de reproducción de estos. Ello puede ser debido a la aparición de nuevos ejemplares, larvas que no han sido eliminadas, o a la eclosión de larvas y huevos preexistentes. Additionally, the population of these larvae is counted at the beginning and subsequently another count that allows the results to be evaluated and, later, after a few days, to measure their reproduction level. This may be due to the appearance of new specimens, larvae that have not been eliminated, or the hatching of pre-existing larvae and eggs.

Descripción detallada de la invención Detailed description of the invention

El método objeto de esta innovación tiene una primer etapa que consiste en el recuento de los organismos presentes en el agua basado en la observación ocular o en la fotografía del área que se está investigando. A continuación, los datos recogidos son traspasados a un procesador matemático y a una memoria de imágenes. The method object of this innovation has a first stage that consists in the count of the organisms present in the water based on the ocular observation or the photograph of the area under investigation. Then, the collected data is transferred to a mathematical processor and an image memory.

HOJA DE REEMPLAZO (Regla 26) Para ello se procede a un recuento de los organismos a eliminar a posteriori en ciertos lugares que permitan tener muéstreos válidos. Esto puede realizarse en el caso de que el agua fluya al efectuar la medición en base a un cierto volumen de agua, o bien en base a un cierto tiempo en que el agua circula entre dos paredes transparentes. El recuento será ocular en ciertos casos y en otros mediante la captura de imágenes que luego son almacenadas en un procesador de datos y posteriormente se realiza el recuento y la comparación. REPLACEMENT SHEET (Rule 26) To do this, we proceed to a recount of the organisms to be eliminated a posteriori in certain places that allow for valid sampling. This can be done in the event that water flows when measuring based on a certain volume of water, or based on a certain time when water circulates between two transparent walls. The count will be ocular in certain cases and in others by capturing images that are then stored in a data processor and subsequently counting and comparing.

En el paso siguiente, un equipo transductor emisor de ondas de ultrasonido, sin contacto físico con la superficie, sino a través del agua de mar, es accionado para eliminar las larvas o evitar su asentamiento. Este equipo puede operar de diversas maneras. O bien el agua es impulsada en un ducto o entre dos paredes frente al transductor subacuático; o bien este se encuentra en un curso de agua de mar, anclado. En estos dos casos el equipo está en posición fija y el agua circula. In the next step, an ultrasound wave emitter transducer equipment, without physical contact with the surface, but through seawater, is actuated to eliminate the larvae or prevent their settlement. This equipment can operate in various ways. Either the water is driven in a pipeline or between two walls in front of the underwater transducer; or this is in a seawater course, anchored. In these two cases the equipment is in a fixed position and the water circulates.

A la inversa, cuando se desea tratar agua de mar contenida en un estanque, un reservorio o también en el mar abierto si fuese el caso, el equipo puede estar anclado y ser orientado en diversos ángulos o bien ser desplazado mecánicamente en el espacio donde haya organismos a eliminar. En ciertos casos, el equipo estará sostenido por un soporte que permita girarlo y orientarlo en distintas posiciones y en otros casos puede preverse un equipo auxiliar que permita desplazarlo de un lado a otro dentro del área que se desea controlar. Este equipo puede flotar o estar anclado. Conversely, when it is desired to treat seawater contained in a pond, a reservoir or also in the open sea, if applicable, the equipment can be anchored and oriented at different angles or be mechanically displaced in the space where there is organisms to eliminate. In certain cases, the equipment will be supported by a support that allows it to rotate and orient it in different positions and in other cases an auxiliary equipment can be provided that allows it to be moved from one side to another within the area to be controlled. This equipment may float or be anchored.

Las ondas de ultrasonido serán emitidas en ciertas frecuencias predeterminadas en función de los organismos a controlar y con una intensidad y una duración también predeterminadas. Así mismo, el procedimiento se puede repetir con ciertos intervalos de tiempo hasta que el efecto deseado sea obtenido. Las The ultrasound waves will be emitted at certain predetermined frequencies depending on the organisms to be controlled and with a predetermined intensity and duration.
