Abstract (en)
[origin: EP0555734A1] In the arrangement for cleaning ground water and the earth through which it flows, the cleaning elements, in particular filter devices, are designed and arranged in such a way that they produce optimum efficiency and guarantee a long service life of the arrangement. This is achieved by largely avoiding vertical filter surfaces and screen walls defining filter chambers, filter chambers with exchangeable filter material, the arrangement and configuration of the conveying means for achieving ground-water circulation and/or by devices for cleaning screen walls of any deposits. <IMAGE>
