TREATMENT ASSESSMENT OF WATER MELON SEEDS AND RINDS AS NATURAL COAGULANTS FOR WATER

Abstract

The research focused on assessment of water melon seed and rinds as a natural coagulants for water treatment, following an experimental framework, this research gathered the waste, prepared aqueous extracts, and dosed turbid water samples while monitoring key quality indicators such as turbidity, pH, color, and suspended solids. Routine jar tests showed that the seed extract cut turbidity by an average of 99.54%, (from 1018NTU down to 4.7NTU) whereas the rind extract delivered a 99.17% drop, (from 1018NTU down to 8.5NTU) with both treatments clarifying water and keeping pH within acceptable ranges. Because seeds outperformed on every measured parameter, the results highlight watermelon waste as a viable, low-cost substitute for synthetic coagulants. Theory and practice thus converge, advancing the field of green water treatment and demonstrating that agricultural by-products can safeguard public health while reducing environmental strain. the reduced TSS for seed average is 95.14% (from 1112mg/L to 54mg/L) while that of rind TSS average is 96.22% (from 1112mg/L to 42mg/L).
