Factors Affecting Solubility

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Microbial Wastewater Treatment

Microbial Wastewater Treatment

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.

Area of Science:

Environmental Science
Water Treatment Technologies
Chemical Engineering

Background:

High phosphorus concentrations in wastewater cause eutrophication and deoxygenation.
Phosphorus removal and recycling are critical for environmental protection and resource recovery.

Purpose of the Study:

To investigate the potential of nanofiltration (NF) for removing and recycling phosphorus from wastewater.
To characterize and test commercial NF membranes for phosphorus-rich solutions.

Main Methods:

Analysis of pulp and paper plant wastewater.
Characterization and performance testing of commercial NF membranes (DK5, MPF34, NF90, NF270, NF200).
Experiments focused on membrane permeability and phosphorus removal efficiency at varying conditions.

Main Results:

NF90 membranes demonstrated the highest phosphorus rejection (>70%) at pH <2 with a feed concentration of 2.5 g/L.
NF90, NF200, and NF270 membranes exhibited higher permeability than DK5 and MPF34.
NF90 performance was sensitive to concentration polarization and fouling, but improved at pH 2 or with sulfuric acid addition.
Acetic acid significantly reduced phosphorus rejection.

Conclusions:

Nanofiltration, particularly using NF90 membranes, is a viable technology for phosphorus removal and potential recycling from industrial wastewater.
Optimizing operational parameters like pH and avoiding specific chemical inhibitors (e.g., acetic acid) is crucial for maximizing NF efficiency in phosphorus removal.
