Abstract

En kassettartad enhet (1) är utformad att i ett aktivt läge placeras upplyftbar i en brunn för att genom filtrering kvarhålla fast material som följer med ned i brunnen rinnande vatten. Enheten uppvisar ett yttre första filterelement (8), från en botten hos detta uppåt skjutande andra filterelement (12) samt ett mellan dessa både filterelement anordnat tredje filterelement (15) som sträcker sig högre upp från nämnda botten än det andra filterelementet och upptill är försett med en dettas av filterväggarna avgränsande inre täckande täckdel (19) och nedtill uppvisar en öppning (20) mellan ett första utrymme (17) mellan det första filterelementet och det tredje filterelementet och ett andra utrymme (18) mellan det andra filterelementet och det tredje filterelementet.A cassette-like unit (1) is designed to be placed in an active position liftable in a well in order to retain by filtration solid material which follows water flowing down into the well. The unit has an outer first filter element (8), from a bottom of this upwardly projecting second filter element (12) and a third filter element (15) arranged between these two filter elements which extends higher up from said bottom than the second filter element and is provided at the top with an inner covering cover part (19) delimiting it from the filter walls and at the bottom having an opening (20) between a first space (17) between the first filter element and the third filter element and a second space (18) between the second filter element and the third filter element .
