Abstract

The work deals with the issues of ammonium nitrogen and phosphate phosphorus removal from wastewater. Natural and modified sorbents: zeolite, glauconite, and bentonite were tested under laboratory conditions. The wastewater after biological treatment with an average ammonium nitrogen concentration of 5 mg/L and an average phosphate phosphorus concentration of 3.4 mg/L was used for experimental studies. Before the test, the phosphate phosphorus concentration in the wastewater was increased to 19.9 mg/L by the addition of potassium hydrophosphate salt. Glauconite (after 3 hours in a muffle furnace at a temperature of 550 °C) had the greatest ability to sorb phosphorus. Under the conditions of this study, the PO4–P sorption efficiency was 58%. Ammonium nitrogen from wastewater was best sorbed by natural glauconite. Under the conditions of this study, the sorption efficiency of NH4–N was 98%. The results showed that the adsorption process on glauconite could be used as an effective method for removing ammonium from wastewater.
