Definitions
- the invention relates to a water treatment plant, in particular ballast water treatment plant, for the removal of sediments and / or removal and / or killing of living organisms, which has at least one filter unit and at least one disinfection unit.
- ballast water Transporting invasive organisms with ballast water is one of the major threats to the oceans. To stabilize the situation, ships must receive ballast water when they are unloaded or not fully loaded. Ships transport sediments and organisms in ballast water, e.g. Algae, and release the latter when discharging in the port of arrival / area. Depending on the route of the ship, these naturally do not occur in this area, can prevail as invasive organisms in suitable living conditions and lack of natural enemies and thus lead to significant ecological, economic and health damage.
- ballast water e.g. Algae
- ballast water management is the ballast water exchange on the high seas, using seawater, the port water is displaced from the ballast water tanks.
- the pumping method is used today or the tanks are first emptied and then refilled with seawater.
- the scientific background is the assumption that Due to the different living conditions, organisms from the port area do not survive on the open sea and vice versa. However, this is not always the case with a wide tolerance range of the organisms and the exchange can never be complete due to the angular ballast water tank construction.
- z For example, in a large crude oil tanker with 100,000 t of ballast water, it can take days to arrive on board. Often, for reasons of safety of the ship and crew, z. B. in bad weather conditions, completely waived the exchange on the high seas.
- ballast water exchange it is therefore necessary to replace the usual ballast water exchange by efficient ballast water treatment on board ships to prevent the further worldwide spread of invasive organisms by transport in ballast water.
- ballast water treatment with high volume flows in the range of 50 - 7000 m 3 / h works without interruption.
- Further requirements include a high level of automation, low maintenance requirements, suitable choice of materials, no increase in corrosion due to the disinfection process and consideration of the installation situation on board.
- ballast water systems which are piping systems for filling and emptying the ballast water tanks
- some of the purified water is used to blow the separators, eg. B. is used for backwashing the filter.
- separators which have a high ballast water netto production even at high sediment levels in ballast water.
- the ballast water treatment plant must be able to cope with all the world's water qualities.
- the biological and chemical-physical Water quality is subject to strong geographical, climatic and seasonal fluctuations.
- Ballast water can consist of river water, brackish water and sea water and thus allows an extraordinary variety of organisms to be removed and / or killed during ballast water treatment.
- the relevant groups of organisms include fish, shellfish, zooplankton, phytoplankton, cysts, bacteria and viruses.
- the particle size distribution and the suspended sediment concentration are decisive for the treatment.
- these additionally depend on the local conditions at the location of the ballast water intake, such as wind and tidal influence, adjacent ship movements, use of the drive and the bow thruster, which lead to the Aufwirbelung deposited sediments and thus increased concentrations.
- the tide-influenced harbors very high sediment concentrations occur.
- ballast water tanks are known with one or more larger mechanical separators, but which do not meet the installation situation on board and, for example. exceed the usual deck height of 2.5 m.
- the deposition of sediment in the ballast water tanks causes high costs due to the loss of cargo capacity and tank cleaning.

- a vent 18 is arranged to degas the pumped water, in particular to remove the hydrogen formed in the electrolytic cell C from the water.
- the detection unit D is operated in the secondary flow to the drain line, since the measurement requires only a small volume of water. Since the measurement signal depends specifically only on the number of living cells, high sediment concentrations do not disturb this measurement.
- the processed, i. filtered and disinfected water is fed to a ballast water tank via port 2.
- a backwash pump E is arranged in the backwash line 19, which is connected via the connection 4 to a water tank, not shown.
- the backwash pump E is used to pump water during the backwashing of the filters 11, 12, 13, provided that a backwash due to a detected excessive pressure drop over the filter unit B is triggered, and the cleaning of the filter 11, 12, 13 at the conclusion of Ballastens. If no fresh water is available for backwashing during the water treatment, when the backwashing is triggered via the pipeline 21, part of the treated water is used for backwashing and conveyed through the backwash pump E.

- the treatment steps of the plant consist of a filtration with filters 11, 12, 13 in the form of disc filters in the filter unit B and a disinfection C, which is based on the electrolysis principle.
- the filter unit B is formed from three parallel filters 11, 12, 13 in the form of disc filters.
- a disc filter forms the filter surface by means of pressed plastic discs. These have grooves in the top and bottom. The grooves intersect when the disks are on top of each other, thus forming an open-pored surface on the outside of the disk pack and internal stopping points. The depth and arrangement of the grooves determines the nominal filter fineness and area. In this filter, both the surface and the depth filtration effect comes into play, so that the real filter fineness and also the filter surface may differ from the nominal one.
- the disinfection unit C is integrated into the pipeline and has a slightly larger circumference than the pipeline itself. It generates oxidative substances from surface water by means of the electrolysis principle.
- four electrode pairs are arranged transversely to the flow direction, which are formed as a grid. At these grids takes place at the water flowing through the electrolysis.
- the grates themselves are equipped with a coating which prevents corrosion, but at the same time ensures electrical conductivity.
- the electrolysis takes place in the low voltage range. Excessive gas formation of hydrogen and oxygen can thus be avoided.
- a detection unit D determines photometrically the number of living organisms of a reference species of a certain size in the course of disinfection.
- the intensity of the disinfection in the disinfection unit C is controlled by the detection unit D, which outputs a signal from the number of living organisms in the course of disinfection. In the control of the disinfection, this leads to the fact that the current is increased or decreased and thus regulates the performance of the disinfection directly on the effect of the oxidizing substances, which are formed in the electrolysis cell, on the living organisms.
- the incoming and outgoing volume flows are detected by means of sensors 10, 22 and the pressures across the filter elements 11, 12, 13 by means of a pressure sensor 14. Further, the determined number of living cells per unit volume of the Detected by the detection unit D water. All collected data is documented, ie stored.

- the backwashing is initiated upon reaching a predetermined differential pressure or a predetermined time interval. A further description of the backwashing takes place in case 2.
- the filters 11, 12, 13 are connected in parallel. This has the advantage that one filter can continue to be flown while another is being cleaned. For the cleaning, the process of disinfection and thus the filtrate of the still flowed filter 11, 12, 13 is used.
- the backwash pump E For cleaning, the backwash pump E must be activated. By switching the flaps, the required water is provided and either taken from the connection 4 a fresh water tank or diverted via the pipe 21 of the treated water.
- the backwash pump E conveys backwards over the filtrate side with an elevated pressure of 6 bar through a filter housing and cleans it off.
- the sludge is discharged via port 3 on the raw water side through a sludge line onboard or stored in a collecting tank.
- the duration of a cleaning is predetermined, for example, 10 sec per single filter 11, 12, 13. If a filter housing cleaned, the flaps put back into the filtration position, so the next filter housing can be cleaned. This is done according to a fixed order, since the differential pressure triggering the backwashing is determined only over the entire series connection.
- the force applied by a spring tension on the discs is released by the pressure of the backwash pump.
- the discs are mounted on a filter kit.
- This filter kit has circumferentially tangentially arranged spray nozzles through which the remind Singer is pressed. This leads to a rotation of the discs, which positively supports the cleaning. If the flap of the backwash is closed again, so the filter insert lowers and the spring force presses the now cleaned discs back to each other.
- the filter housings are cleaned to prevent bacterial contamination and in preparation for further ballast operations. For this purpose, raw water is still filtered.
- the process differs from backwashing in that the filter housings are no longer used after filtration for filtration and that the disinfecting power is set to the maximum for this purpose.
- the raw water is now filtered, passes through the disinfection C and is fed directly to the backwash pump E via the pipe 21.
- An inflow into the ballast water tanks is no longer provided.
- the water is discarded outboard.
- the cleaning of the last two filter housings can no longer be carried out exclusively with raw water, since no filtrate container is available.
- the flap is switched before the ballast water pump A. Then by means of the ballast water pump A from a nearby ballast water tank already Filtered and disinfected ballast water taken or available on board technical water or drinking water via the port 4 without disinfection or via the connection 5 from the ballast water tank again passed through the disinfection and used for backwashing.
- ballast water In order to release ballast water, the water is pumped from the ballast water tanks via port 5.
- the filters 11, 12, 13 are bypassed via the installed bypass 20 or the raw water line of the shut-off by closing the controllable valves filter 11, 12, 13 itself used as a bypass.
- the ballast water is now led directly through the disinfection C and directed outboard.
- the disinfection is adjusted according to requirements with the signal of the detection unit D in order to comply with the discharge standard.
- the dose of disinfection by increasing the residence time is additionally increased by throttling the volume flow to be delivered.
- ballast water pumps which must promote a high volume flow
- injectors are used for emptying the ballast tanks. They protect the ballast water pump from cavitation during the emptying of the ballast tanks.
- the ballast water pump delivers filtered and disinfected seawater through the injector.
- This motive flow which is passed through a Laval nozzle, creates a negative pressure with which the ballast tanks can be emptied. Both the motive flow and the ballast water from the emptying are once again subjected to disinfection before both currents are led overboard. 5 Case: Bypass emergency operation
- a bypass 20 leads to the entire apparatus or modules.
