The Effectiveness of Tubular Ceramic Membrane Made from Seashell and Clay for Groundwater Filtration

Abstract

The Karawang Regency is located on the coast and is the largest industrial area in West Java. However, this has led to groundwater seepage issues that cause the water to taste salty and cause yellow stains. To solve these issues, a study was conducted to filter the groundwater using tubular ceramic membranes. This study created tubular ceramic membranes using three different composition; Clay:Seashell = 60%:30% (CM-1); 45%:45% (CM-2); 30%:60% (CM-3); and 10% zeolite. The ceramic membranes were sintered at 1000°C for 10 hours. The research aimed to analyze how different compositions of ceramic membrane materials affected the efficiency of reducing pH, manganese, Total Dissolved Solids, salinity, and hardness. This ceramic membrane has a good effectiveness level completed with the best tubular ceramic membrane variant in reducing water pH levels being CM-1 (7.2-7.5), CM-1 is the best reduction of TDS by 284.66 mg/L, CM-2 is the best reduction of Mn metal by 0.235 mg/L, CM-3 is the best reduction in hardness by 84.333 ppm, and CM-1 is the best reduction in salinity by 108 ppm.
