Optimization of Desalination Media Based on Blood Clam Shell Waste (Anadara granosa) and Zeolite for Salinity Reduction of Water in the Coastal Area of Sungsang

The availability of clean water in the coastal area of Sungsang faces significant challenges due to seawater intrusion and limited water treatment infrastructure. This study aims to evaluate the effectiveness of a combination of blood cockle (Anadara granosa) shell powder and zeolite as an environmentally friendly desalination solution. The research was conducted through laboratory experiments with treatments including variations in immersion time (10, 20, 30, 40, 50, 60 minutes), activation temperature (50, 100, 150, 200, 250, 300 °C), activation duration (30, 60, 90, 120, 150, 180 minutes), and zeolite mass (5, 10, 15, 20, 25, 30 grams). The main parameters observed were salinity reduction and desalination efficiency, measured using a salinity meter (AR-8012). The results showed that optimal conditions were achieved at an immersion time of 30 minutes, activation temperature of 200 °C, activation time of 90 minutes, and zeolite mass of 25 grams, resulting in a salinity reduction of 25.4 ppt and a maximum desalination efficiency of 74.8%. This combination of biomaterials demonstrates great potential as an energy-efficient and sustainable alternative for seawater desalination in coastal regions.
