In a first treatment step part of at least one difficulty biodegradable or non-biodegradable organic compound is oxidized in polluted water by bringing said polluted water into contact with an ozone containing gas. The effluent is subsequently diluted with an aqueous liquid before a second treatment with ozone is carried out. If the concentration of the organic compound is still not sufficiently low, the treated effluent is diluted again and subjected to a further treatment with ozone. It was found that a more effective ozone treatment was obtained by the dilution or dilutions and that in particular no pH control was needed, so that no formation of additional salts occurred.

Method of purifying polluted water

The invention relates to the employment of at least one oxygen-fuel burner in a particular manner in glass melting cross-fired regenerative furnaces. By operating oxygen-fuel burners positioned in particular places in a cross-fired regenerative furnace in an appropriate manner, the glass melting can be accomplished without disrupting the flame momentum of the air-fuel burners, thereby improvidng the efficiency of the glass melting and increasing the production of the glass products.
