“…Al Hassa Oasis is a significant irrigation facility in Saudi Arabia, serving 328 million m 3 of water, covering almost 22,000 farms. The excess drainage water is channeled through an earthen drainage network and distributed into two evaporation lakes, Al-Asfar and Al Uyoun [18]. Previous research studies have examined the water quality of Al-Asfar and Al Uyoun evaporation lakes using methodologies such as geographical information systems (GIS), hydrogeological studies, chemical studies, and remote sensing to design strategies for reusing the lake water for agricultural activities in Al Hassa Oasis [18].…”

Water composition analysis of Al-Asfar and Al Uyoun lakes has established relatively low salinity levels, and future development and planning strategies have been proposed to re-treat this water for its reuse in agricultural and land irrigation activities [18].…”

In this study, we aimed to explore the commercial potential of various microalgae variants found in Al-Asfar Lake, Saudi Arabia, which have not been extensively investigated previously. We conducted a comprehensive analysis of the metabolic profiles of algae isolated from Al-Asfar Lake. The isolated algae were subjected to molecular analysis using specific primers for the Chlorophyceae class to confirm their identity. Subsequently, we compared the concentration of metabolites in the locally isolated Chlorella vulgaris from Al-Asfar Lake with five commercially available algae (Tetraselmis, Nannochloropsis, Chlorella vulgaris, Spirulina, and Isochrysis). To perform the metabolomics analysis, we employed untargeted ultra-performance liquid chromatography (UPLC) coupled with mass spectrometry (MS) analysis, which yielded a total of 168 metabolites from the microalgae samples. The data were further analyzed using MetaboAnalyst. The results revealed two distinct clusters of microalgae: the first cluster comprised Chlorella vulgaris and the microalgae isolated from the lake, while the second cluster consisted of two sub-clusters, with Isochrysis grouped with Tetraselmis, and Nannochloropsis clustered with Spirulina. Notably, the metabolites of Al-Asfar Lake algae showed a remarkable similarity to Chlorella vulgaris. These findings have significant implications for the environmental aspect of Al-Asfar Lake, shedding light on critical insights into the metabolites and commercial potential of the lake’s microalgae. The valuable insights gained from this research can be utilized to investigate the impact of nutrient abundance on the lake’s biodiversity, enhance microalgal biomass production for biofuel applications, and explore the reuse of lake water in agriculture and environmental restoration projects. Overall, our study provides important groundwork for understanding the potential of Al-Asfar Lake microalgae and their application in various industries, contributing to the sustainable development and environmental health of the region.

This paper presents an experimental study aimed at assessing the suitability of rice husk ash (RHA) treated black cotton soil as a barrier in Municipal Solid Waste (MSW) containment facility. Laboratory tests were conducted on black cotton soil treated with 5, 10 and 15% RHA at moulding water contents of 2 and 4% on both wet and dry sides of optimum moisture content (OMC) using British Standard Heavy (BSH) compactive effort. Index properties, hydraulic conductivity (k), volumetric shrinkage strain (VSS), and unconfined compressive strength (UCS) tests were conducted on all the samples. The results obtained indicated that the soil was classified as A-7-5(18) according to the American Association of States Highway and Transport Officials (AASHTO) classification system and Silt of high plasticity (MH) in accordance with the Unified Soil Classification System (USCS). It was observed that addition of RHA was accompanied with decrease in the plasticity index from 24 to as low as 3%. An improvement in the moisture-density relationship of the soils showed an increase in Maximum Dry Density (MDD) from 1.46 to 1.52 Mg/m3 as well as a decrease from 24.5 to 21.2% in OMC. The increase in RHA contents up to 10% brought about an improvement in the strength of the soil specimens by almost 332.4kN/m2 at 2% on the dry side of OMC. The VSS decreases with increase in RHA content to achieve the minimum shrinkage strain of 4.1% at 5% RHA treatment.
