    Phospat is the key element of nutrien that cause eutrophication. Recently, many home industri such as Laundry can effect to the stream, it caused eutrophication. Phospat is one of builders in deterjen that cause eutrophication. Multivalen Metal Ions is one of Coagulant that used as Phospat removal from domestic waste, esspesially deterjen by Coagulation – Floculation test. The most commonly used coagulants of Multivalen Metal Ions are Ferric chloride (FeCl3 ) and Aluminium Oxide (Al2O3). There are many variation of Concentration that added into wastewater as coagulant that can remove Phospat from effluent pipe and drainage. The aim of Coagulation Floculation test in this research is to know the optimum dosage of Ferric Chloride and Aluminium Oxide to remove phospat. The result of this research is that Aluminium Oxide more effective to remove phospat than Ferric Chloride to remove phospat from effluent pipe and drainage. Aluminium Oxide removed phospat in effluent pipe around 66,49 %. The abbility of Ferric Chloride to removed phospat around 54,25 %. Aluminium Oxide more effective than Ferric Chloride, it caused that Aluminium Oxide can make floc destabilisation at pH 6 – 8. Efficiency of Ferric Chloride and Aluminium Oxide almost the same to remove phospat in drainage. The abbility to remove phospat is around 73,9 % of Ferric Chloride and 74,85 % of Aluminium Oxide. The ability of Ferric Chloride is significant to remove phospat in drainage, it cause Ferric Chloride has abbility to remove phospat at pH 8 or more.
