Definitions
- the present invention relates to the use of a composition containing CaCO 3 , CaCl 2 and / or CaSO 4 and NaHCO 3 as an additive for natural and synthetic sea water, in which marine animals are reared or kept.
- the breeding basins or pond systems are usually connected to natural water sources, for example to the open sea, via corresponding pipelines.
- the quality of the water in the breeding tanks can be greatly affected by the quality of the seawater supplied, by the metabolic processes of the marine animals kept or by contaminated rearing feed.
- the present invention was therefore based on the object of finding a composition with which it is possible to stabilize the pH value and the lime hardness and thus the buffer capacity in rearing stations for seawater fish and also in seawater aquariums, which leads to a stabilization of the biological activity and the self-cleaning power of the water.
- the present invention relates to the use of a composition containing
- the water quality in marine aquariums and also in breeding stations of marine animals can be stabilized in such a way that even the presence of pollutants, such as for example copper, aluminum or iron compounds do not affect the water quality.
- the composition used according to the invention has proven to be particularly suitable for the breeding of crustaceans, such as shrimps.
- Customary commercially available calcium salts are obtained from naturally occurring minerals and can contain admixtures of other components which, however, generally do not impair the action of the composition according to the invention.
- magnesium salts can also be present in accordance with the naturally occurring contents. For particularly sensitive animals, qualities with high levels of purity, in particular components of analytical quality, are preferred.
- any CaCO 3 which is commercially available can be used as component A.
- Freshly precipitated CaCO 3 has proven to be particularly cheap. In the case of very fine-grained qualities (diameter approx. 1 ⁇ m), very small contents of calcium carbonate (proportions of material from 0.01 to 0.1 based on the quantity of B) are sufficient.
- Component A can contain up to 25% by weight of MgCO 3 . However, the MgCO 3 content should not be too high, since there is a risk of excessive alkalizing effects, with the result of the onset of decarbonization and thus limescale precipitation (softening). This is diametrically opposed to the meaning of the invention.
- any calcium salts such as the chlorides and sulfates or mixtures thereof can be used as component B, calcium chloride being preferred. Even if the calcium salts in water have a pH in the acidic range, a stable pH in the range of 6.5 and 9.5 is achieved by adding this component.
- the selection of these calcium salts is not limited to any special qualities; any commercially available calcium salts can be used.
- CaCl 2 , CaSO and magnesium salts in particular from the group consisting of chloride, sulfate, carbonate, oxide and sulfate, can also be used as component B, the molar ratio of calcium salts to magnesium salts being able to vary within wide ranges and preferably from 0.8: 1 to 10: 1, particularly preferably from 1: 1 to 6: 1.
- the substance-to-substance ratio of components A and B is generally 0.1: 1 to 2: 1, preferably 1: 1, 3 to 1, 3: 1. If there are alkaline sea waters, then the Component B preferably in an excess, the molar ratio is then preferably 1: 1, 3 to 1: 2.
- the third component of the composition contains NaHCO 3 .
- KHCO 3 may optionally also be present as a further component. Commercial products of any quality can also be used in this case. KHCO 3 is used particularly when low-potassium seawater is available. In this case, NaHCO 3 and KHCO 3 are present in substance ratios of 10: 1 to 1: 1. The KHCO 3 can also be used in excess, but this is not preferred for reasons of cost.
- Components B and C are usually present in molar ratios of 1: 3 to 2: 1, preferably 1: 2.3 to 1: 1.7, particularly preferably 1: 2.1 to 1: 1.9.
- composition used according to the invention can contain further customary additives which can be contained in additives for sea water which is used for shrimp farming.
- additives for sea water which is used for shrimp farming are examples of these additives.
- the composition according to the invention can also contain soda, Na 2 CO 3 , as component D. Soda also leads to a stabilization of the water quality of highly polluted sea water, ie if a high microbial degradation work is done.
- the molar ratio of components C: D is preferably in the range from 1: 0.3 to 1: 0.01.
- composition used according to the invention can also contain further components which are used in particular to adjust origin-oriented water qualities, such as. B. Strontium salts and rare earth salts.
- a further embodiment of the present invention relates to a composition which, in addition to components A, B and C, contains sodium chloride, NaCl.
- a composition is added to fresh water as a ready-made seawater mixture.
- a ready-made seawater mixture can also contain soda and the above-mentioned salts for fine adjustment of the water quality.
- the individual components can be added as a mixture or in succession to the sea water. It is also possible to first use components B and C and, if appropriate, soda, Na CO 3 , and to later distribute component A over the seawater to the bottom.
- composition according to the invention can be added in any manner. In the case of small areas of water, distribution can be carried out by hand; in the case of large areas, mechanical forms of distribution, especially through the air, have proven to be favorable.
- the composition used according to the invention can be added via special systems. Dosing devices can be used both in aquariums and in open water areas. Automatic adjustment of the water quality is possible via dosing devices that are equipped with the appropriate analysis technology to directly analyze the ingredients of the water to be treated and the pH value.
- Another object of the present invention is a method for the treatment of water for the rearing and keeping of marine animals, which is characterized in that a composition containing an additive for the sea water
- NaHCO 3 and optionally KHCO 3 where components A and B are present in molar ratios of 0.01: 1 to 2: 1 and components B and C in molar ratios of 1: 3 to 2: 1, and in which one dissolves components B, CaCl 2 and / or CaSO 4 and optionally magnesium salts, NaHCO 3 and optionally KHCO 3 , separately in H 2 O, mixes the solutions with the sea water and passes the resulting mixture over or through CaCO 3 .
- the CaCO3 is present as a calcium bed. It has proven to be advantageous to mix components B and C in proportion to the water to be treated. Components B and C are preferably present in molar ratios of 1: 3 to 2: 1, preferably 1: 2.3 to 1: 1.7, particularly preferably 1: 2.1 to 1: 1.9. The amount of CaCO3 used is not important in this embodiment.
- the water to be processed, containing components B and C, is passed over the CaCO3.
- the CaCO3 dissolves in accordance with the solution equilibrium in the water, the excess remains as a solid, e.g. B. in a fixed bed, back.
- a total dosage of 5 - 1500 mg / l of the preparation is particularly useful.
- the most common doses are between 50 and 300 mg / l.
- the minimum requirements for drinking water with 100 to 200 mg / l are met.
