The effectiveness of ozone (O3) in eliminating various types microorganisms, as well oxidizing a wide range contaminants present wastewater, and drinking water, is extensively documented the literature, along with required concentrations, contact times (Ct values), reaction mechanisms for different pollutants, overall efficiency. This article presents comprehensive review on use aqueous O3 treatment disinfection, specifically low-contaminant domestic greywater (LGW), providing information its integration into design small-scale systems. Additionally, to complement theoretical findings, experimental tests were conducted using portable generator an operational facility treating (GW) from handwashing sinks. results confirmed that concentration increases over time but decreases volume water be treated increases. Water analysis showed significant reductions BOD5, turbidity, total suspended solids after treatment. Furthermore, demonstrated presence microorganisms LGW minimal, case fecal coliforms, ensuring 1 Log disinfection level this type system. O3, sole system, oxidation potential nearly twice chlorine, proved highly effective systems, promoting sustainable practices, resource conservation, environmental protection, public health.

Assessment of Potential Aquifer Recharge Zones in the Locumba Basin, Arid Region of the Atacama Desert Using Integration of Two MCDM Methods: Fuzzy AHP and TOPSIS

Natural aquifers used for human consumption are among the most important resources in world. The Locumba basin faces significant challenges due to its limited water availability local population. In this way, search possible aquifer recharge zones is crucial work urban development areas that have scarcity. To evaluate problem, research proposes use of hybrid Fuzzy AHP methodology conjunction with TOPSIS algorithm obtain a potential map. Ten factors influence productivity and capacity an were implemented, which subjected their weighting. Using algorithm, delineation favorable high was established. result shows influential precipitation, permeability, slopes, obtained highest weights 0.22, 0.19, 0.17, respectively. parallel, highlights distributed basin, classified into five categories: very (13%), (28%), moderate (15%), low (16%). adapted seeks be first step toward effective resource management study area.
