Assessment of nonwoven geotextiles usefulness in order to ground protection from clogging

Use of natural waters which include organic and mineral suspended matter, suspensions, bacteria, microorganisms for infi ltration facilities supply contributes to clogging of pores in the interior of the fi ltering medium as well as to formation of clogging mat at the infi ltration surface. Consequences of silting-up enforce using solution designed to regeneration fi ltration ability of ground. One of methods using in order to devices protection from deep clogging are nonvowen geotextiles. This paper presents the research results indicating effectiveness of nonvowen geotextiles as layer which separate clogged mat from fi ltering medium
