Definitions
- 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
- 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.
- 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.
- REPLACEMENT BLADE (Rule 26) glue of the coating of an airplane.
- Another CN patent 101412548 discloses a method for treating organic liquid effluents. It uses an ultrasonic oxidation method together with an electrochemical oxidation technique.
- CN18282 9 is another Chinese patent that protects a fault detector in an underwater pipeline using ultrasound and an electromechanical test.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the equipment 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.
- 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.
- the ultrasound waves will be emitted at certain predetermined frequencies depending on the organisms to be controlled and with a predetermined intensity and duration. Also, the procedure can be repeated with certain time intervals until the desired effect is obtained.
- Ultrasonic frequencies to be used are in the range of 20 kHz and 200 kHz and the powers to be used in ultrasound emitting equipment of the order of 20 watts to 1,500 watts, although it is not ruled out to use higher powers.
