Pemanfaatan kembali air limbah terolah dengan sistem wetland untuk pembuatan kulit glace

Tanneries use large quantities of water and produce high pollutant load. Wastewater recycling is an effective way to conserve water supplies. The purpose of this study was to reuse wastewater that has been treated with a wetland system to save water and to apply cleaner production in tannery industry. The treated wastewater was tested in accordance with the test requirements of water used for leather tanning process. The treated wastewater test results met the requirements of SNI 06-0649-1989 Water for the tanning process. Furthermore, treated wastewater was used for leather tanning process with variations of wastewater used were 0, 25, 50, 75 and 100%. The resulting leather was tested in accordance with SNI 06-0253-1989 Quality requirement of goat glace leather. The test results met the SNI. Utilization of 75 % wastewater gave the best result.
