Definitions
- the invention refers to the electrochemical method of sterilizing the sea water, which is used as ballast for the balance of ships.
- sea water which is used as ballast for the balance of ships, from one sea area to another, has caused a major problem to the sea environment, because pathogenic organisms that are dangerous for spreading illnesses, are being transported and the transferee species, that do not have their natural enemies at the new sea environment, are multiplied in the expense of the native organisms, thus changing the area's variety of live organisms.
- the problem is dealt by changing the sea ballast at water depths of 2000m, but this is something that besides the cost, cannot accomplish a change of the sea ballast more than 90%, or by using chemicals, which cause an environmental decay, or with UV rays, which are ineffective, due to the fact that they do not have a residual action.
- the electrochemical method of sterilizing the sea ballast uses sea water for the production of the oxidants, such as O 3 , Cl 2 , ClO 2 , is very simple in use and totally effective to the sterilization of the sea ballast and can be applied to great flo s of sea water.
- the sea water which enters the bilge of the ship, passes through a separation hydro cyclone and the whole or a part of it is led directly or through a bypass to an electrolytic cell, which is supported by a voltage supply of 3 to 30 Volts and an intensity of 5 to 600 Ambers.
- the total amount of water gathers to the ballast docks of the ship.
- a REDOX meter that is connected with a PLC, which, depending on the REDOX value, gives a dosing pump, which is within a production and storage container of oxidant made of sea water, the instruction to inject it to the water ballast docks.
- a second REDOX meter that is inside the docks, gives the instruction to inject oxidation reduction agents, a solution of acid Sodium Thiosulfate or Sodium Thiosulfate from storage containers. Furthermore, through the line of sea water collection and rejection, there are nozzles that inject a solution of acid Sodium Thiosulfate or Sodium Thiosulfate from storage containers after a PLC instruction and through a dosing pump during the rejection in order to inactivate all the oxidants that are within the sea ballast so as to avoid the environment decay.
- a hydro cyclone that separates solids from liquids (a) is put at an inflow line of sea ballast 300m3/h.
- the solids left on the grid end up to a bucket (b) in order to be farther treated.
- the already separated from solids sea water, containing a salt concentration of 2.9% to 3.5%, is led to the electrolytic cell (c), which is supported by a supply of direct current (k) with a voltage of 0.5 to 30 Volts and an intensity of 5 to 600 Ambers.
- k direct current
- the already electrolyzed water along with the oxidants ends to the ballast dock (I).
- a hydro cyclone that separates solids from liquids (a) is put at an inflow line of sea ballast 300m3 h.
- the solids left on the grid end up to a bucket (b) in order to be farther treated.
- the already separated from solids sea water, ends to the ballast dock (T).
- the oxidant is produced by the electrolytic cell (c), which is supported by a supply of direct current (k) with a voltage of 0.5 to 30 Volts and an intensity of 5 to 600 Ambers, by the recirculation of the sea water through the pump (d) inside the container (j).
- a REDOX meter (f) Inside the ballast dock f ), there is a REDOX meter (f), which is connected to the PLC (e) and if the residual oxidants at the outflow are more than what is provided by the legislation, gives the instruction to a dosing pump (m) that is put inside a container with a solution of Sodium Thiosulfate (n) to inject it in the ballast dock (f) in order to inactivate any possible residual oxidants.
