Definitions

  • Electrochemical based water treatment system refers to the application of multiple devices in concert, one being capable of generating electrical current via the submergence of electrodes to facilitate electrochemical reactions in salt water and another simultaneously capable of removing the residual chemical by-products of the electrochemical reactions.
  • the resulting synergistic actions of the different system devices creates a healthy aquatic environment for sea animals during live transport to market, storage and during production.
  • a critical part of the aquaculture value chain is the removal of ammonia and the disinfection of salt water.
  • the ability to remove ammonia and disinfect water affects aquatic life health and meat quality. It is also required to enable extended-duration transportation of live fish to market, as opposed to frozen fish. Each of these is critical to the economic value for the fish.
  • a salt-water generator is a relatively high-voltage and high-power device which serves to remove ammonia, and produces diatomic chlorine (Ch) from chloride, which is a critical part of the process to oxidize pathogens within the water.
  • substantially means sufficient to function for its intended purpose. As such, the term “substantially” means a small, insignificant amount from absolute or perfect conditions, dimensions, measurements, results, etc., as would be expected by one skilled in the art, but which does not significantly affect overall performance, and allows for variation. "Substantially” when used for a number or parameter or property that can be expressed as a number means within 10 to 15 percent. Further, the stated features and/or configurations or embodiments thereof the suggested intent may be applied as seen fit to certain operating conditions or environments by one experienced in the field of art.
  • a Y-strainer with a screen size of, but not limited to, 1/32” is placed immediately downstream of the reactor to remove large flakes of precipitated salt that may form, and consequently released into the water stream, within the embodiment of the reactor during system operation.
  • This system can operate under fixed, continuously recirculating flow driven by a simple on-off switch, or via a remote monitoring and control system with alarms and notifications as needed.
  • the monitoring system will typically involve the Electrochemical Reactor and VFD pump, but as described above, may also involve monitoring the service requirements of the activated carbon filtration and catalyst columns.
  • Control of the pump and reactor will involve the monitoring of ammonium concentration, water flow rate, and the reactor voltage and amperage. Alarms with notifications for these parameters can then be set based on minimum and maximum operating set points to indicate possible malfunctions relative to the pump or reactor.
  • control is tied to the reactor, which is specifically designed to treat X mg of ammonium per second based on a fixed voltage and current at the reactor.
  • the size of X is set to be some amount greater than (the maximum anticipated ammonium per liter) * (maximum system flow rate, liter/sec). The purpose of this is to enable the ammonium to be treated and provide sufficient additional oxidation capacity for treating various pathogens entrained in the water. In this way, an optimal control system may be engaged to ensure ammonium levels are kept below a given set point while minimizing the flow rate through the system to minimize operating cost.
  • the input water tank had total ammonia nitrogen (TAN) of 250 mcg/L with no detectable chloramines, nitrates, or free chlorine, and the water temperature was 25°C.
  • the flow rate through the reactor was set at 14 GPM (53 LPM).
  • the TAN, chloramines, nitrates, and free chlorine for the water in the output tank were all non-detectable, demonstrating 100% removal of the TAN and no hazardous byproducts.

Abstract

L'invention concerne un système efficace et évolutif pour la destruction des virus, des bactéries, des spores fongiques et du microzooplancton, ainsi que l'élimination de l'ammoniac pour répondre aux besoins physiologiques de la vie aquatique et assurer la prévention de la formation de biofilms et l'élimination des espèces d'algues nuisibles de l'eau salée utilisée pour soutenir la vie aquatique en eau salée. Le système convient parfaitement aux systèmes d'aquaculture en recirculation, aux installations de stockage de poissons, au stockage temporaire mobile, au transport de poissons vivants, aux réservoirs de stockage des bateaux de pêche, aux écloseries, aux bateaux-viviers, aux aquariums, à l'élevage de crevettes en étang, aux points de vente au détail de poissons et aux centres de distribution de produits de la mer.
