Pervious pavements emerge as an alternative for good management of surface runoff, providing the opportunity to quickly and efficiently reduce potential flooding reuse rainwater. However, mechanical hydraulic performance material have been extensively evaluated at laboratory level, leaving aside how will behave in field its exposure accelerate loss properties (clogging). In this sense, research...

Using experiments and numerical simulations, we study the clogging transition of a single pore by colloidal particles. We are able to link dynamics flow decline within pores formed particle accumulation inside clog. show that most is due reduction cross section as it gets fouled also modification paths when only few layers have accumulated at rear

The conventional practice of using 0.45 or 0.40 microm membranes to distinguish between the particulate and dissolved phases in natural waters neglects the importance of colloids. Many of the colloids in natural waters pass through 0.45 or 0.40 microm membranes, but a significant fraction at the upper end of the colloidal particle size range is retained. Membrane clogging during filtration decr...
