Process for treating industrial effluents |
| abstract |
The invention relates to a method for cleaning contaminated process waternfrom plants for iron and / or steel production and processing, for example fromnRolling mills or descaling systems, the contaminated process waternfirst be pre-cleaned in a coarse separation, then in at leastna further cleaning stage and finally after a cooling stepnback in the iron and / or steel manufacturing or processing process (s)nbe recycled, the final cleaning being carried out by means of belt filtrationnand the process water is a layer of fine-grained filter aid materialnflow through. The cleaned process water is recycled and thatnFilter aid material either regenerated or in an iron ornSteel manufacturing process used.n n n The process enables a particularly cost-saving cleaning of contaminated process water. |
