Lampiran 1. Langkah Penelitian
Air Limbah dengan kadar phosphate tinggi
Pengukuran Suhu dan pH sebelum perlakuan
Masukkan dalam wadah sebanyak 1 liter
Masukkan Poly Aluminium Chloride (PAC).
Proses Koagulasi dengan pengadukan cepat 70 rpm selama 1 menit
Proses Flokulasi dengan pengadukan lambat 50 rpm selama 15 menit
Proses Sedimentasi dengan waktu 30 menit
Pengukuran Suhu dan pH setelah perlakuan
Air yang telah olahan
Pengukuran kadar phosphate
