Experimental dataset on the application of aloe vera gel as a natural coagulant for water treatment

This paper presents a comprehensive dataset from laboratory jar test experiments evaluating the performance of <i>Aloe vera</i> gel as a natural coagulant for water treatment, focusing on turbidity reduction. The coagulant was prepared through gel extraction, homogenization with tap water, and paper filtration. Synthetic turbid water was produced by dispersing bentonite in tap water to reach initial turbidity levels of 50, 100, 200, and 300 NTU. Coagulation tests were conducted under controlled laboratory conditions using a jar test apparatus, including rapid mixing, coagulant dosing, floc formation, and a 60-minute sedimentation stage. Turbidity was measured with a calibrated turbidimeter at 10-minute intervals for one hour, generating a dataset that records initial and residual turbidity values for different coagulant dosages. The dataset is organized in tabular format and includes metadata on coagulant preparation, synthetic water formulation, and operational parameters to ensure reproducibility. The results confirmed a consistent and significant reduction in turbidity across all tested conditions, demonstrating the effectiveness of <i>Aloe vera</i> gel as a natural coagulant. These data can support comparative studies on natural coagulants, modeling of coagulation dynamics, optimization of treatment conditions in low-resource contexts, and the validation of sustainable alternatives to chemical coagulants.
