the structures built on them prone to subsidence. In the recent decades, buildings constructed in southern area of Mashhad Metropolitan, Iran, have been widely faced with this problem. Since permeability and chemical composition of these soils are varying in time...

Superabsorbent polymers (SAP) are materials that absorb and retain water and aqueous solutions up to several hundred times their own weights within their structure, even under pressure. Reducing the time of dewatering by permeable membrane...

showed that the reduction of permeability is very sharp as soon as the biofilm appears, and this sharp decrease seems related with the existence of biopolymers. The relationships between permeability and porosity allowed the reconstruction of the porosity...

. In experiments carried out, the effect of superabsorbent, type of bed (horizontal and vertical) and time on normal method of yoghurt concentration (use of permeable membrane, were studied. The percentage of dry solids and total soluble solids of dewatered samples...
