Definitions

  • the subject of the invention is an evaporative water desalination system, a scale build-up prevention method in evaporative water desalination systems and a use of water saturated with micro-nano bubbles in evaporative desalination systems.
  • the invention belongs to the field of water desalination systems .
  • evaporative desalination systems require a pretreatment of saline feed water. This is connected with formation of carbonates and build-up thereof in a system resulting from saline feed water degassing and separation of carbon dioxide which is removed outside through a vacuum system. Moreover, sulfur and magnesium compounds existing in the saline feed water have properties of effective scale deposition on heat exchanger tubing. Conventional desalination systems rely on adding inhibitors to a saline feed water, usually at the level of 5ppm of the saline water intake.
  • a maximum temperature of multi-stage evaporative system operation being approximately 70°C is defined by a chemical composition of feed water, since above this temperature a risk of scaling in heat exchanger piping is very high.
  • the abovementioned circumstances render a continuous operation of evaporative water desalination systems impossible. Operation downtimes result from a necessity to conduct periodic maintenance procedures.
  • a solution relying on a dosage of inhibitors aiming at slowing down scale formation and deposition process in desalination system is a costly procedure.
  • the substance has been dosed in a concentration ranging from 2ppm to 8ppm and the best results have been obtained at 5ppm.
  • the difference between the present invention and the state of art is that neutral micro-nano bubbles (MNB) are dosed instead of chemicals to influence the inhibition of the ions of calcium, sulfur and carbonates and maintain a solubility of carbon dioxide in the solution.
  • MNB neutral micro-nano bubbles
  • the saline water is saturated with micro-nano bubbles before the intake to MED system using the oxygen, ozone or carbon dioxide.
  • A.E. A1. -Rawaj feh, H.E.S. Fath i A.A. Mabtouk in their article sufferedIntegrated Salts Precipitation and Nano-Filtration as Pretreatment of Multistage Flash Desalination System” describe an application of nano-filtration membranes to lower the concentration of calcium carbonate and sulfur in the saline water delivered to the system, which led to reducing the concentration of sulfur ions by 95% and calcium carbonate by 37% in a stream of saline water delivered for thermal desalination. Although it has nearly doubled the efficiency of desalination process by increasing a maximum temperature of system operation, it has not eliminated a necessity of using chemicals. The difference between the present invention and the state of art is that a dosage of chemicals has been eliminated completely and no element to be replaced due to nanoflitration membrane deterioration or cleaning is applied to the system.

  • This solution is especially well suited for a food industry (for example pumping of milk) thanks to a favorable influence of MNB on dissolving of milk additives while reducing pumping costs.
  • the invention provides dosing of MNB to a low viscosity liquid containing over 90% of pure water to maximize a heat exchange as well as cleaning and disinfecting properties .
  • the present invention unlike other known from the prior art and conventionally used chemical dosing stations (for example inhibitors), utilizes MNB (Micro Nano Bubble) technology based on saturating a saline make-up water with bubbles of oxygen, ozone, carbon dioxide or a mixture thereof, having a diameter of less than 0.1mm to reduce scale formation and improve energy efficiency of a system. Breaking micro-nano bubbles generate ultrasonic waves having a cleaning effect on all solid surfaces. Breaking of micro-nano bubbles results in emergence of OH* hydroxyl radicals being very strong oxidants, stronger than ozone and atomic oxygen.
  • MNB Micro Nano Bubble
  • Hydroxyl radicals destroy all microorganisms such as bacteria or viruses and have a positive effect on an existing scale - breaking MNB' s mechanically clean a heat exchanging surface by protecting it against build-up of carbonates and similar scale forming minerals as well as protecting from formation of biofilms. Additionally, presence of MNB' s in water changes a solubility of minerals and shifts a saturation point thereof, thus greatly benefiting evaporative desalination systems. In the same time, radicals emerging at MNB breakdown enhance evaporation due to a large number of nucleation sites in water.
