Dissolved phosphorus levels in fresh municipal wastewater

Abstract

The influence of wastewater lag-time to the concentrations of dissolved phosphorus was investigated. The dissolved phosphorus levels of fresh municipal wastewater and the rate at which phosphorus dissolves in untreated municipal water was studied. Dissolved phosphorus initially accounted for 34% of total phosphorus in the used water. The level of dissolved phosphorus in wastewater doubled during half a year of storage. The dissolving of phosphorus was most rapid in the first 10 days when dissolved phosphorus levels increased by approximately 1% per day.
