摘要:
The present invention concerns a process for treating water and the use of calcium carbonate in such a process. In particular, the present invention is directed to a process for remineralization of water comprising the steps of providing feed water, providing an aqueous solution of calcium carbonate, wherein the aqueous solution of calcium carbonate comprises dissolved calcium carbonate and reaction species thereof, and combining the feed water and the aqueous calcium carbonate solution.

The invention relates to a method and installation for treating water for human consumption, for an industrial process, for agricultural purposes or for other purposes. The method used to remineralize raw water comprises a stage in which carbon dioxide and at least one inorganic base are injected. According to the invention, the method comprises the following stages: the flow Q of raw water is separated into a flow Q1 and a flow Q2; only flow Q1 is remineralized by injecting carbon dioxide and at least one inorganic base, said remineralization being carried out in at least one remineralization basin; remineralized flow Q1 is mixed with untreated flow Q2. .

Das Verfahren zur biologischen Wärmeerzeugung sieht vor, dass die in einem Belüftungsbehälter (11) sich befindlichen organischen Abfallstoffe, z.B. Klärschlamm, durch Einführen von sauerstoffhaltigem Gas durch thermophile Bakterien abgebaut werden. Das aus dem Klärschlamm austretende Gas wird zum Teil wieder in einem Kreislauf (11, 33,31,43,35,44) in die Abfallstoffe zurückgeführt. Dadurch werden die Wärmeverluste reduziert. Das zurückgeführte Gas wird mit Frischluft oder reinem Sauerstoff angereichert. Die Anreicherung des zurückgeführten Gases erfolgt durch eine automatisch durch ein Ventil (51) verschliessbare Oeffnung (49) entsprechend dem Kohlendioxydgehalt im Gas des Behälterraums (43) oder dem Sauerstoffgehalt im Klärschlamm.

The invention relates to a process for treating a hydrocarbonaceous waste material, in particular a rolling scale slurry and/or grinding slurry, the waste material being heated in a dryer, preferably moving, by the indirect supply of heat, and in the process hydrocarbons, if appropriate together with other volatile components, in particular H 2 O, being removed. In this process, in the dryer, at low temperature, the hydrocarbons are broken down in a specific way, the hydrocarbons being broken down by chemical and/or radiation means, which effect decomposition of the hydrocarbons of low volatility into highly volatile hydrocarbons, preferably decomposing high molecular weight hydrocarbons into lower molecular weight hydrocarbons, and the hydrocarbons, if appropriate together with the other volatile components in particular together with the H 2 O, are at least partially discharged, in particular by suction, from the vessel. The invention also relates to a apparatus for treating a hydrocarbonaceous waste material.

The present invention is an automated aquaculture system which comprises: one or more culture tanks (10) connected to a closed system of filters (22) and ultraviolet (80) or ozone sources for water purification prior to returning water to the culture tanks (10). Also disclosed as part of the system are automated biofilters (60, 70) that automatically monitor water conditions in the system, and video cameras in the tanks that monitor growth and condition of the animals in the tank. This invention is also a process useful for culturing an aquatic species, using the disclosed systems. Preferred species include shrimp, squid, marine fishes and fingerlings and marine mollusks.

The present invention concerns a process for treating water and the use of calcium carbonate in such a process. In particular, the present invention is directed to a process for remineralization of water comprising the steps of (a) providing feed water having a concentration of carbon dioxide of at least 20 mg/l, preferably in a range of 25 to 100 mg/l, and more preferably in a range of 30 to 60 mg/l, (b) providing an aqueous slurry comprising micronized calcium carbonate, and (c) combining the feed water of step (a) and the aqueous slurry of step (b) in order to obtain remineralized water.
