- The purpose of this research was to design the liquid waste treatment system using ceramic membrane filtration method. The ceramic filter was made of a mixture of clay and coal fly-ash with certain compositions. Rig in this experiment was equipped with PVC piping system, flowmeter, pressure gauge, and the circulation pump. The liquid waste tested are obtained from the secondary effluent of a fertilizer industry. The measured were the feed flow rate, permeate flow rate, TDS, pH, heavy metal content, and ammonia content according to the Indonesian National Standard (SNI) of effluent water quality. The results showed that ceramic membrane can decrease the ammonia concentration in the secondary effluent up to 96%. Heavy metal ions (Fe, Cr and Mn) can be reduced to 60.9%, 39.4% and 38.4% respectively. The best composition of membrane/filter was achieved at a ratio of 77.5% clay, 20% fly-ash and 2.5% of iron powder.
