This work deals with the analysis of the cleaning mechanism of polymer woven filter media. It reports parametric studies for the cleaning of filter media using continuous and pulsed flows for different kinds of impurities and filter geometries. There the focus is on the development of dimensionless operation numbers, which can be used to predict the cleaning result of the respective filter medium.

Dissolved and suspended particulate matter (SPM) bound Cu, Zn, Ni, As, Pb, Mn, and Fe are common pollutants in surface and groundwater of the Akaki Sub-Basin.This work (1) presents results of water quality analysis and (2) evaluates an innovative approach for removing heavy metals from polluted water using natural materials. Removal capacities of the filter media for Cu, Zn, Ni, and Pb reach 90%. The main removal mechanisms involved are weak sorption and surface precipitation.

Biofiltration is a technology of great interest since the costs of installation and, above all, exploitation costs are much lower than those associated with other technologies based on physical–chemical processes. Nowadays, the use of biofiltration is increasing every day. On the other hand, the physicochemical filtration process is a successful technology in numerous applications in the field of water treatment. This issue of the journal is focused on the treatment of different types of effluents through filtration: Drinking water and wastewater. Different technologies are analysed: Filtration through biochar from agricultural by-products; biological active carbon (BAC); electroadsorption using a commercial granular activated carbon as the adsorbent; filtration through sand, anthracite and expanded clay; granular activated carbon (GAC) as part of a tertiary treatment for wastewater reuse.
Technology: general issues --- bacteriological contamination of water --- biofiltration --- biological stability --- water treatment --- granular activated carbon --- adsorption --- autonomous prototype --- emerging contaminants --- filtration --- reclaimed water --- safe agricultural reuse --- expanded clay --- Filtralite --- Mono Multi --- sand --- anthracite --- granular filter media --- backwash --- headloss --- clean-bed expansion --- bed fluidization --- peanut shell --- “chonta” pulp --- corn cob --- biochar --- lead --- cadmium --- drinking water --- electroadsortion --- thrialomethanes --- bromides --- bacteriological contamination of water --- biofiltration --- biological stability --- water treatment --- granular activated carbon --- adsorption --- autonomous prototype --- emerging contaminants --- filtration --- reclaimed water --- safe agricultural reuse --- expanded clay --- Filtralite --- Mono Multi --- sand --- anthracite --- granular filter media --- backwash --- headloss --- clean-bed expansion --- bed fluidization --- peanut shell --- “chonta” pulp --- corn cob --- biochar --- lead --- cadmium --- drinking water --- electroadsortion --- thrialomethanes --- bromides

The development of materials from industrial wastes has attracted the attention of the research community for years. A material's physico-chemical characteristics have specific impacts its properties and their application in environmental, energetic, and biomedical areas, such as in pollutant removal; CO2 capture; energy storage; catalytic oxidation and reduction processes; the conversion of biomass to biofuels; and drug delivery. Examples of such materials are activated carbons, clays, and zeolites, among others. The aim of this Special Issue is to collect the recent advances and progresses developed in this field considering valorised materials from industrial wastes and their applications in environmental, energetic, and biomedical areas.

The rapid urbanization, sometimes lacking adequate planning and design, has led to worsening city syndrome situations, such as urban flooding, water pollution, heat island effects, and ecologic deterioration. Sponge city construction have become the new paradigm for a sustainable urban stormwater management strategy. Deviating from the traditional rapid draining approach, the new paradigm calls for the use of natural systems, such as soil and vegetation, as part of the urban runoff control strategy. It has become a widespread focus in urban water management research and practices globally. In this Special Issue reprint, there are 13 original scientific articles that address the different related urban runoff control issues. We are happy to see that all papers presented findings characterized as innovative and methodologically new. We hope that the readers can enjoy and learn deeply about urban runoff control and sponge city construction using the published material, and we hope that sharing of the researches results with the scientific community, policymakers and stakeholders can prompt the urban runoff control and sponge city construction globally.
