Riverbank filtration: a frontline treatment method for surface and groundwater-African perspective.

Riverbank filtration (RBF) has emerged as a crucial and functional water treatment method, particularly effective in improving surface water quality. This review is aimed at assessing the suitability of RBF in regions with limited access to clean water, such as Africa, where it has the potential to alleviate water scarcity and enhance water security. This review used various studies, highlighting the principles, applications, and advancements of RBF worldwide.

Physicochemical and microbiological quality of rainwater harvested in underground retention tanks.

A study was made of the physicochemical properties (among others: pH, temperature, conductivity, hardness, chlorides, dissolved oxygen, ammonia, nitrites, nitrates, manganese, iron) and microbiological quality (coliform, psychrophilic and mesophilic microorganisms) of rainwater harvested from the roofs of three large buildings and from a parking lot, stored in three large underground tanks (with storage volume from 60 m to ca. 200 m), including the variability of the quality. The underground tanks were located in the city of Poznań, and were characterized by different parameters, rainwater sources, rainwater treatment processes, and types of rainwater use.
