Research on Ammonium Treatment from Cassava Starch Factory Wastewater Using the SNAP Model
Abstract
This study applies the Single-stage Nitrogen removal using Anammox and Partial nitritation - SNAP model to remove organic compounds, especially NH4+, from wastewater. The experiment was carried out using real wastewater taken from the anaerobic tank of the wastewater treatment system of Nam Bao Tin Import Export Co., Ltd. The study was conducted in three phases with NH4+ concentrations of 58 mg/L, 90 mg/L, and 120 mg/L, respectively. The NH4+ removal efficiency reached 91.8% on the 51st day of operation (phase 2) and formed small amounts of nitrate. Also at this stage, the PO43- and COD removal efficiency were 61.9% and 40.7%, respectively. Microbial density reached 1.5×107 CFU/mL by the end of phase 2.
