“…64 In most of the cases, arsenic adsorption on iron compounds could t the Langmuir model better than Freundlich model. 65 For example, As(III) adsorption on hematite, 66 As(III) and As(V) adsorption on magnetite, 67 goethite, 68 amorphous iron hydroxide 69 and magnetite-maghemite nanoparticles 70 could be well described by Langmuir model, indicating the monolayer adsorption on energetically equivalent sites. However, As(V) adsorption on granular ferric hydroxide (GFH) tted Freundlich model better with a high correlation coefficient (R 2 > 0.99), 71 indicating the heterogeneous active sites distributed on GFH.…”

“…Besides, these works are usually focused on different features, such as water quality aspects or efficiency of the filtration process, or on specific topics, such as the removal of specific substances from drinking water [2][3][4][5]. An ad-hoc pilot circuit was, therefore, designed and built at the Laboratory of Environmental and Maritime Hydraulics (LIDAM) of the Department of Civil Engineering (DiCiv), University of Salerno.…”

Among the treatment processes in water networks-of increasing importance in recent decades due to the progressive deterioration of water quality-filtration still represents a major solution. The present work focuses in particular on the filtration of drinking water with wire-wound filter cartridges, the most widely used type of cartridge in domestic plants among the commercially available cartridges, due to their efficiency and relatively low costs. Specifically, the hydraulic performance of these cartridges was analyzed, i.e., mainly the effect of their introduction into a hydraulic system in terms of head losses. The local pressure drops produced by the cartridges may, in fact, create problems in hydraulic plants already characterized by low pressures, where pressure levels may fall below the minimum limit recommended to ensure the smooth operation of domestic devices. To this aim, a set of experiments was conducted in a pilot circuit in the Laboratory of Environmental and Maritime Hydraulics (LIDAM) at University of Salerno, where pressure drops produced by the cartridges were measured in different operating conditions. The artificially dirty conditions of the wire-wound filters were analyzed in order to evaluate the effect of the filter obstruction. The analysis provided some useful information about the performance and duration of these filters, as well as suggestions for more efficient commercial filters.

Liquid treatment processes have been assuming increasing importance in recent decades with the progressive industrialization to ensure public health security for drinking water or to prevent economic damage when safeguarding important production processes. Major investments have been devoted to the research, study, and design of innovative products that are able to respond to the demands of the market, which currently offer several solutions, among which filtration treatment still represents a major one. This work focuses, in particular, on filtration of drinking water with filter cartridges, with the aim to test their hydraulic performance and, particularly, to evaluate the head losses that they produce when introduced into a hydraulic system. The local pressure drops, in fact, may compromise hydraulic plants already characterized by low pressures. What is more, this condition is increasingly likely in supplying networks due to the coexistence of several factors, such as water losses due to failures and inefficient maintenance, severe and prolonged droughts, and increased water demand related to social and economic development. In these systems, the insertion of filtration cartridges can make the pressure levels fall below the minimum limit recommended to ensure the smooth operation of domestic devices. More in detail, in the present study the behavior of seven different commercial filter cartridges was analyzed through a set of experiments conducted in a pilot circuit at the Laboratory of Environmental and Maritime Hydraulics (LIDAM), University of Salerno. These tests have been performed in different operating conditions, collecting pressure data through various pressure gauges. The analysis proved that for common values of operating flow rates in domestic plants the pressure drops in the filter can be of the order of some meters and provided some useful information for the choice of the proper cartridge in low-pressure distribution systems.
