Activation of Lattice Oxygen in LaFe (Oxy)Hydroxides for Efficient Phosphorus Removal.

Environmental Science and Technology, 2019
Lanthanum (La)-based materials have been recognized as promising adsorbents for aqueous phosphate removal. The incorporation of base metals into La (oxy)hydroxides represents an effective strategy to improve adsorption performance. Understanding how base

Biological Phosphorus Removal Processes

2010
Enhanced biological phosphorus removal (EBPR) processes developed for wastewater treatment are mainly based on the enrichment of activated sludge with phosphorus-accumulating organisms under alternative anaerobic–aerobic conditions. According to the literature information of the EBPR processes, this chapter attempts to review the biochemical models ...

Phosphorus Removal: Field Analysis

Journal of the Environmental Engineering Division, 1981
The Great Lakes Water Quality Agreement of 1978 established by the International Joint Commission of Canada and the United States called for the achievement of 0.5 mg/\Il\N total phosphorus as the maximum effluent level in all Lake Erie and Lake Ontario municipal wastewater treatment plants discharging greater than 3785 m³/day.

Enhanced Biological Phosphorus Removal and Recovery

Water Environment Research, 2008
Activated sludge systems designed for enhanced nutrient removal are based on the principle of altering anaerobic and aerobic conditions for growth of microorganisms with a high capacity of phosphorus accumulation. Most often, filamentous bacteria constitute a component of the activated sludge microflora.

Municipal wastewater phosphorus removal by coagulation

Environmental Technology, 2010
This study investigated the chemical removal of phosphorus from wastewater by means of adsorption and precipitation. Using secondary effluent from municipal wastewater treatment plants as the model wastewater, phosphorus precipitation was tested with four commonly used metal salt coagulants, and phosphorus adsorption was explored by column experiments ...

Induction of phosphorus removal in an enhanced biological phosphorus removal bacterial population

Water Research, 1997
Abstract Volatile fatty acids (VFAs) resulting from prefermentation of influent glucose were used to cultivate a bacterial population capable of enhanced biological phosphorus removal (EBPR) in two identical anerobic/aerobic sequencing batch reactors (SBRs).

Efficiency of nitrogen and phosphorus removal by six macrophytes from eutrophic water

International journal of phytoremediation, 2019
Increased nitrogen and phosphorus pollution causes eutrophication in water bodies. Using aquatic plants to remove nutrients from water is an attractive phytoremediation.

Phosphorus Removal in Vegetated Filter Strips

Journal of Environment Quality, 2003
ABSTRACTVegetated filter strips (VFS) are used recently for removal, at or near the source, of sediment and sediment‐bound chemicals from cropland runoff. Vegetation within the flowpath increases water infiltration and decreases water turbulence, thus enhancing pollutant removal by sedimentation within filter media and infiltration through the filter ...
