Title: Paint and print shop waste water processing
Inventor: SCHMIDT HANS-JUERGEN DIPL CHEM
IPC: C02F1/32
Filed: 1992-11-17
Abstract: To clean waste water from vehicle service stations an oxidn. and microfiltration stage are in succession to oxidise and separate the components of the waste water, pref. the heavy metals.     Pref. the oxidn. action is effected by ozone, ultra-violet radiation or a catalytic treatment, or a combination of methods. The raw water is mixed with a part flow in the oxidation stage for the sediment to be deposited free of germs and smell, and clean water is passed back into circulation. The prefiltered water is oxidised for about 120 mins. per charge, by recirculation in a part circuit during this time span. The mixing of the water treated in the oxidation stage catches sludge in the collected raw water. The microfiltration is through ceramic material, which tolerates ozone, as a long-life membrane.

Patent DE-4313931-A1 (DE)
Title: Arrangement for retaining the pollutants from polluted landfill leachate waters
IPC: A62D3/00
Filed: 1993-04-28
Abstract: In an arrangement for retaining the pollutants from polluted landfill leachate waters, at least one adsorption layer is assigned to at least one sealing layer. The adsorption layer comprises a mixture of power station filter ash, containing reactive silicas, and an aqueous electrolyte solution, in particular containing alkali metal salts or alkaline earth metal salts. Since fly ashes and filter dusts from bituminous coal and brown coal power stations generally have a very high content of reactive silicas, by addition of an electrolyte solution it is possible to achieve a gel formation, which results in a large internal surface area having a correspondingly high adsorption capacity being generated. The adsorption layer is thus able to bind by physical and/or chemical adsorption pollutants contained in the leachate water exiting from the landfill by diffusion and/or convection.

Title: Method for controlling the particle removal from a target object
Inventor: DELAN AXEL DIPL PHYS
IPC: B23K15/08
Filed: 1993-10-13
Abstract: The invention relates to a method for controlling a particle beam during thermal removal (sublimation, evaporation) of material from a target object, such as is used, for example, for electron-beam evaporation, which is intended to achieve crater-free removal. A movement, which is slow in comparison with the thermal inertia, of the beam position, which can be carried out in combination with a fast movement for wobbling, guides the removal point over the material stock in such a manner that a uniform removal is performed which avoids craters. If this slow movement is controlled by a computer, the movement sequence can constantly be optimised from measured data obtained during the movement. Electron-beam evaporation of sublimated materials (e.g. graphite), in particular for layer separation.
