- Medicinal Properties: Traditionally, tamarind has been used for medicinal purposes such as treating stomach discomfort, aiding digestion, and as a laxative due to its high fiber content.
- Seed Extract as Coagulant: The seeds of tamarind are found to be effective as a natural coagulant. They contain a high protein content that acts as a natural polyelectrolyte, which can be used in water treatment processes to remove suspended solids and color from wastewater¹².
- Environmental Impact: Using tamarind seed extract as a bio-coagulant is environmentally friendly and can be a sustainable alternative to synthetic coagulants in water treatment¹.
The application of tamarind seed extract in water treatment is particularly noteworthy. Studies have shown that it can significantly reduce levels of suspended solids and color in wastewater, making it a promising solution for industries such as batik production, which often discharge colored wastewater into rivers. This use of tamarind seed extract aligns with the growing interest in sustainable and eco-friendly water purification methods.
