Abstract :
The potential of watermelon seed as natural coagulant for water purification was evaluated. It was aimed at identifying watermelon seed as a possible replacement for alum and other synthetic polyelectrolyte in treating water Jar test experiment was performed on raw water from Dakachi Dam, Zaria, Kaduna State with initial turbidity of 62.6NTU. Results obtained showed that at a dosage of 0.1g/L with stirring time of 8 minutes and mixing speed of 100rpm, the highest turbidity reduction to 3.68 NTU was observed. This was below the World Health Organizations (WHO) recommended value of 5NTU. However, the best color removal was 30TCU but not up to the WHO recommended value of 15 TCU. The results showed that watermelon seed can be used as a natural coagulant for water treatment.
