Abstract: Method for controlling a water treatment installation having a supply, an ozonization stage, a transfer stage, a biological filter and a discharge having the following steps: measuring a first parameter set in the supply, wherein, a measurement for a first concentration of micro-contaminations and/or a nitrite concentration is determined; controlling the ozonization stage in such a manner that an ozone supply is carried out in a preselected ratio to the measured first parameter set; measuring a second parameter set in the transfer stage, wherein, a measurement for a second concentration of micro-contaminations is determined; controlling the ozonization; measuring a third parameter set in the discharge, wherein, with reference to the third parameter set, a measurement of a third concentration of micro-contaminations is determined; if the measurement for the concentration of micro-contaminations exceeds a predetermined maximum value in the discharge, increasing the ozone supply.

Abstract: A method for treating contaminated liquids in a flow by ozone, wherein the ozone is fed in gas form into the flow at one point and then is mixed into the flow in stages by mixers following one another in the flow direction, so that an absolute quantity of introduced ozone increases after each mixer until a feed efficiency of more than 95 percent is reached.

Abstract: Method for controlling a water treatment installation having a supply, an ozonisation stage, a transfer stage, a biological filter and a discharge having the following steps: measuring a first parameter set in the supply, wherein, a measurement for a first concentration of micro-contaminations and/or a nitrite concentration is determined; controlling the ozonisation stage in such a manner that an ozone supply is carried out in a preselected ratio to the measured first parameter set; measuring a second parameter set in the transfer stage, wherein, a measurement for a second concentration of micro-contaminations is determined; controlling the ozonisation; measuring a third parameter set in the discharge, wherein, with reference to the third parameter set, a measurement of a third concentration of micro-contaminations is determined; if the measurement for the concentration of micro-contaminations exceeds a predetermined maximum value in the discharge, increasing the ozone supply.

Abstract: A device and a method for treating liquids by ozone, including a pipe in which a main flow of the liquid is guided in a flow direction from an inlet to an outlet, an ozone feed point at which ozone can be introduced in gas form into the main flow, and at least two mixers which are located downstream of the ozone feed point, wherein the mixers are arranged at a distance from one another, and wherein at least one reaction zone is formed between the mixers, and wherein the mixers are designed in such a way that they each dissolve only a portion of the ozone in the main flow that has been introduced in gas form.

Abstract: A method for treating a prebleached chemical pulp including a step of ozone treatment of the pulp, carried out at a temperature above 60° C., advantageously above 65° C. and even more advantageously above or equal to 70° C.

Abstract: The invention relates to a method for treating water, especially waste water and drinking water, containing both pathogenic germs and a substance which is difficult to decompose and is from the group comprising persistent substances, endocrine substances, odorous substances, and dyestuffs, by means of ozone supply and UV radiation. The inventive method comprises the following steps: a) ozone is supplied in a concentration of between 0.1 g/m3 and 15 g/m3; and b) UV rays are radiated in a wavelength range of between 200 nm and 300 nm and in a dose of between 50 J/m2 and 2,000 J/m2.

Abstract: The invention relates to the oxidative treatment of bulk material in a vessel. The bulk material to be treated is placed in the vessel, and is humidified therein with water or an aqueous solution to such an extent that it can be treated with an O2/O3 gas mixture in such a way that the desired end product has a determined pH value or a determined solubility or a determined polarity or a determined solubility behaviour and/or particle size distribution. The inventive method enables bulk material to be very effectively oxidised by means of minimal amounts of ozone in an O2/O3 gas mixture, in such a way that between 70 and 100% of the ozone parts enter into a reaction.
