Amorphous silicates having small particles with large surface area, were found to have high non-specific adsorption capacity. Escherichia coli T4 bacteriophage was used as a model in this research. Investigations have shown an adsorption capacity of up to 99% on different tested commercially available silicates. Optimal conditions for the adsorption of T4 bacteriophage on various silicates were determined. Amorphous silicates may be used in purification of water from viral contaminants. A silicate-containing model unit for filtration by adsorption of viruses is described.

The current study addresses the pressing issue of unsustainable water management, particularly in regions experiencing high water stress. It focuses on examining the viability of polymeric membranes composed of biobased materials, mainly chitosan, for various sustainable water management solutions. The membranes evaluated in the study were blends of PVC with either chitosan-silica or charcoal-silica, designed to enhance their functionality and performance.

Due to synergistically enhanced separation and degradation performances, photocatalytic membranes offer an environmentally friendly and energy-sustainable method for water purification. However, a comprehensive review on preparation and application of photocatalytic membranes is still lacking. Systematically comparing different photocatalytic membrane fabrication methods and revealing the underlying mechanisms of their respective applications are of particular interest.

E-mail: ORCID: 0000-0003-1086-1181.
The present paper comprises a systematic survey of trematodes and acanthocephalans based on helminthological examinations of 64 specimens of 14 species of freshwater fishes, belonging to six families of four fish orders, mostly from localities in Hubei Province, central China, collected in the autumn of 2002. A total of 15 trematode species (in 12 families) and 5 acanthocephalan species (in four families) was recorded. Almost all parasites are briefly described and illustrated and problems concerning their morphology, taxonomy, hosts and geographical distribution are discussed.

Contamination by heavy metals (HMs) in aquatic ecosystems is a worldwide issue. Therefore, a feasible solution is crucial for underdeveloped and developing countries. Waste-derived materials (WDMs) exhibit unique physical and chemical properties that promote diverse mechanisms for the removal of HMs in constructed wetlands (CWs).
