A simultaneous removal of ammonium and turbidity via an adsorptive coagulation for drinking water treatment process

The utilization of natural zeolite (NZ) as an adsorbent for NH4 + removal was investigated. Three types of NZ (i.e., NZ01, NZ02, and NZ03) were characterized, and their NH4 + adsorption process in aqueous solution was evaluated. The effect of pH towards NH4 + adsorption showed that the NZ01 has the...
