And more is on the way: Only 8% of domestic and industrial wastewater is treated in developing countries, compared with 70% in high-income countries. In developed countries, solid sludge resulting from bacterial digestion in wastewater treatment plants is commonly incinerated or applied to farmland, where it can contaminate soil.

Biodegradation of Chemicals in Unspiked - pubs.acs.org

The OECD 309 guideline uses spiked incubation tests to provide data on biodegradation kinetics in surface waters. However, potential limitations of spiking test chemicals into the studied water have not been investigated. We conducted the OECD 309 test with unspiked surface water relying on chemical residues present in the water. Parallel experiments were conducted with the same water spiked

Is There a Precipitation Sequence in Municipal Wastewater

Electrochemical wastewater treatment can induce calcium phosphate precipitation on the cathode surface. This provides a simple yet efficient way for extracting phosphorus from municipal wastewater without dosing chemicals. However, the precipitation of amorphous calcium phosphate (ACP) is accompanied by the precipitation of calcite (CaCO3) and brucite (Mg(OH)2).

Meta-Analysis of Mass Balances Examining Chemical Fate

Mass balances are an instructive means for investigating the fate of chemicals during wastewater treatment. In addition to the aqueous-phase removal efficiency (Φ), they can inform on chemical partitioning, transformation, and persistence, as well as on the chemical loading to streams and soils receiving, respectively, treated effluent and digested sewage sludge (biosolids).

Removal of Two Polycyclic Musks in Sewage Treatment Plants

In the current study, the removal of slowly degradable hydrophobic chemicals in sewage treatment plants (STPs) has been evaluated with emphasis on the combination of free and total concentration data. Free and total concentrations of two polycyclic musks were determined in each compartment of four STPs. The free concentration of the polycyclic musks remains virtually constant throughout all

Is There a Precipitation Sequence in Municipal Wastewater

Introduction. Municipal wastewater is a significant source of contaminants but can be an important source of nutrients as well, i.e., phosphorus (P). 1−3 P often is considered to be the principal stimulant of eutrophication. However, it is also a limited and essential resource. 4 To bridge the gap of P being too much as a pollutant and too little as a resource, it is suggested to remove and

Current research trends on microplastic pollution

Microplastics have been widely considered as contaminants for the environment and biota. Till now, most previous studies have focused on the identification and characterization of microplastics in freshwater, sea water, and the terrestrial environment. Although microplastics have been extensively detected in the wastewater, research in this area is still lacking and not thoroughly understood.
