- the invention relates to a new, easy-to-use and effective device for cleaning finely divided aqueous phases containing waste or pollutant phases, preferably oil / water emulsions, such as those used in particular as waste water, waste water, water-lacquer residue water, rinse water, condensates,
- Compressor condensates, cooling lubricants and / or cooling water are obtained in commercial companies, which has a pump for conveying the contaminated aqueous phase into a device, preferably having at least one ceramic tube filter, for separating the pollutant, in particular oil phase, and water phase from one another with separate discharges for the comprises aqueous filtrate or ° permeate, which is relieved of pollutants, and separate phases in concentrate, which has an increased load.
- the invention has set itself the task of a low-maintenance, flexible in terms of its fields of application, easy to use, no special infrastructure investments required device for the separation of pollutants from in particular in the above-mentioned companies and in the above-mentioned companies and in the above-mentioned amounts of waste water to create a wide variety of types, in particular emulsions of hydrophobic and aqueous phases.
- the invention relates to a device of the type described at the outset, which is characterized in that it is in situ, preferably entirely, in a container, in particular in a drum, for collecting and receiving the pollutant, in particular oil, to be separated - / Water phase mixture, insertable unit of a pump equipped with manipulation aids, preferably a fluid-tight centrifugal submersible pump, at least one, preferably directly, phase separation module connected to its outlet side with a drainage for filtrate or permeate designed for external discharge and for one Recirculation of the concentrate in the container of trained concentrate discharge is formed.
- the new device is particularly flexible in use.
- the above-mentioned, in particular oil-contaminated, aqueous phases of the most varied types occur in most cases at irregular time intervals and with different periods of time. They are collected from the place of their occurrence - for example, the oil / water emulsions that occur as cooling lubricants in metal-cutting machines such as lathes - mostly in containers already available in commercial operations, such as in particular cylindrical metal drums, e.g. with 200 1 content, and were previously disposed of after filling the barrels.
- the device according to the invention which usually weighs significantly less than 20 kg and typically essentially only requires a power socket, is placed in the barrel with the irregularly flowing emulsion with its submersible pump in the upright position.
- the end of the permeate discharge hose can be inserted into a floor drain that is usually present in such plants.
- the wastewater that has been oil-relieved in the filtration module of the modular phase separation device can be below the permissible limit values are passed directly to a sewer system.
- oil / water emulsion results in an enrichment of oil in a 2001 barrel, in which the effectiveness of the device deteriorates, e.g. 25% oil in the aqueous phase.
- the new compact device is placed in the same and can process the contaminated water without any lengthy interruption without any traffic jam, while the previous drum is ready for special disposal.
- the new compact device in particular if it is equipped with a submersible pump, has the further advantage that separate work and rinsing containers, supporting frames and the like can be added to the infrastructure, such as a control cabinet. can be dispensed with.
- the pump takes over the load-bearing function for switching elements suction strainer, filter module and return line as well as their mouth.
- the essential component of the new device is a module with ceramic
- the ceramic membranes consist of a large-pore support body and the actual membrane, which is sintered on as a coating with a defined pore size (separation limit).
- the medium to be filtered is pumped out of the waste water barrel through the module and back into the waste water barrel.
- the pore size of the ceramic membrane can e.g. be dimensioned so that dirt and oil are safely retained and only pure water can penetrate.
- the device With the device, a large proportion of the heavily polluted wastewater is transferred to environmentally compatible wastewater at the point of origin, leaving a small volume for removal and special disposal.
- the device according to the invention is advantageously designed such that the outlet of the concentrate return is arranged in the near and / or level area of the suction opening of the pump, preferably just below its level. This causes an approximately horizontal cross-flow in the emulsion, which causes a stirring movement of the barrel contents which is advantageous for the homogenization.
- the device can be constructed in such a way that the opening of a collecting drum for commercial wastewater as described above does not have to have a substantially larger cross section than the submersible pump suction part or foot usually enclosed by the prefilter in a basket-like manner.
- the elongated, tubular filter module can be arranged upright directly above this suction foot part where the part of the pump housing enclosing the drive is narrower than its foot body.

- a practical and robust design such as that of An s u c h 4, has the advantage that the new emulsion processing device is able to withstand the harsh operating conditions that are quite common in the trade without damage that impairs its functionality.
- the mechanical connecting elements can, advantageously detachable, connecting webs, clamps and the like. between filter module, return line and their mouth area on the one hand and the robust housing of the submersible pump on the other.
- the submersible pump can be installed practically alone in the waste water sump in the collecting vessel.
- a hose made of mechanically and chemically resistant material extends from the outlet side and supplies, for example, a filter module attached to the barrel edge outside the collecting container, for example with a simple hook.
- a, preferably hose-like, permeate discharge is led into a drain for waste water and, on the other hand, a hose-like return is emanated from it, through which concentrate loaded with increasing amounts of pollutants, in particular oil, to a concentrate arranged in the area of the pump foot part and with it connected mouthpiece is conveyed back into the container.
- a high level of operational reliability, even when using waste water tanks with a low buffer capacity, and when the contaminated aqueous phases are often very irregular, can be achieved with an embodiment of the new water purification device that is fluid-level-assured.
- nspruch A 9 in particular in coaxial arrangement of the suction pipe and the concentrate discharge and -Ausmündung can be obtained by the proximity of the intake and Ausforceström 'ung be achieved a kind of injector effect • that ensures an intensive mixing of the entire barrel content, especially if there is a high enrichment of the oil content due to refinement.
- an embodiment variant according to A n s r u c h 10 is preferred which precludes thermal overloading of the device and does not allow the degree of occupancy of the filter to exceed a certain value, which is particularly advantageous for its rapid regeneration.
- the regeneration of the device - and this is a further particular advantage of the same - can be carried out in a simple manner by placing it as a whole in a washing solution, e.g. based on a non-ionic surfactant, loaded container and is kept in operation for some time in the same way as in the normal phase mixture separation.

- the device is advantageously installed in the vicinity of the location where the medium to be processed is generated. Warm water for cleaning the filter module is an advantage. It can be placed in a container with a minimum diameter of 400 mm and a flat bottom. A standard drum, 200 1 made of sheet metal, is best suited, so the heat is dissipated well. The container is to ind. + 85 ° C temperature resistant. It is beneficial to maintain the permissible ambient temperatures of around +3 to + 40 ° C. At temperatures below + 3 ° C, frost protection measures are beneficial.
- the device should preferably be supplied with emulsions without free-floating oil. Non-emulsified oil phase reduces performance.
- the waste water drum must be loaded in such a way that no coarse impurities are filled in. Solids would clog the pre-filter screen. 200 ⁇ pre-filtering is recommended.
