The role of settling velocity formulation in the determination of gully pot trapping efficiency: comparison between analytical and experimental data
Roadside gully pots are the connecting points between surface runoff and the underground drainage network; therefore they can be considered as the most superficial component of urban drainage systems. Gully pots are supposed to trap particulate matter washed off the catchment surface, but also to collect and convey stormwater into the network. The continuous accumulation of particulate matter ...

When water suffers from high turbidity, Filtronics is the clear solution
Water loses its transparency and takes on a hazy appearance when it contains a large quantity of suspended solid particles. While even a moderate lack of clarity is noticeable to even casual observers, the average person would probably describe a sample of such water as “cloudy” or “murky.” The technical term – turbidity – is not widely known to laymen outside ...

Sampling, testing and modeling particle size distribution in urban catch basins
The study analyzed the particle size distribution of particulate matter (PM) retained in two catch basins located, respectively, near a parking lot and a traffic intersection with common high levels of traffic activity. Also, the treatment performance of a filter medium was evaluated by laboratory testing. The experimental treatment results and the field data were then used as inputs to a ...
