Pengaruh Massa Dan Waktu Kontak Adsorben Dari Tanah Gambut Dalam Penyisihan L…

ABSTRACT Peat soil as an adsorbent in peat water treatment is located in Sabak Permai Village, Sabak Auh District, Siak Regency. This study aims to study the effect of mass variation and contact time of peat soil adsorbent on the efficiency of Fe, Mn and color removal in peat water. The experiment was carried out by adsorption at a speed of 125 rpm by varying the mass (5, 10, 15, 20 g/L) a…
