An experimental methodology is presented to compare the performance of small (100 L) and large (1,000 L) scale reactors designed for algae remediation of landfill wastewater. System characteristics, including surface area to volume ratio, retention time, biomass density, and wastewater feed concentrations, can be adjusted based on application.

Virus concentration from environmental water and wastewater samples is a challenging task, carried out primarily for the identification and quantification of viruses. While several virus concentration methods have been developed and tested, we demonstrate here the effectiveness of ultrafiltration and skimmed milk flocculation for RNA viruses with different sample types.

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.

A concentration cell is a type of a voltaic cell constructed by connecting two almost identical half-cells, both based on the same half-reaction and using the same electrode, differing only in the concentration of one redox species. A concentration cell's potential, therefore, is determined only by the concentration difference of the particular redox species. Consider the following voltaic cell: From the given information, the cell potential of this concentration cell can be calculated using...

Selection begins with the target’s size and other relevant properties. Membrane filtration, centrifugation, precipitation, and adsorption do not suit every microorganism, chemical, or particulate contaminant in the same way. The preferred approach must retain the target while removing water efficiently, helping produce a measurable sample that remains suitable for interpretation.
Concentration conditions affect both target integrity and how accurately the concentrated sample represents the original wastewater. If the target is not preserved during processing, measurement may become less reliable even when the sample contains sufficient material for detection. Appropriate conditions therefore support dependable estimates of contaminant levels and strengthen environmental interpretation.
These approaches use different separation principles to retain target material while reducing the water volume. Membrane filtration is selected according to retention by a membrane, whereas centrifugation, precipitation, and adsorption rely on the target’s broader properties. Comparing these options helps researchers choose a method suited to the microorganism, chemical, or particulate contaminant being measured.
A practical workflow starts by identifying the microorganism, chemical, or particulate contaminant of interest and considering its size and properties. Researchers then select a suitable concentration approach, apply conditions that preserve the target, and measure the resulting concentrated sample. The findings can be interpreted in relation to contaminant levels in the original wastewater.
Wastewater concentration is most useful when a target occurs at levels too low for reliable direct detection or measurement. Increasing the target amount per unit volume improves analytical sensitivity, allowing monitoring programs to examine contaminants that might otherwise be difficult to measure. This supports pollution assessment, pathogen surveillance, and broader environmental monitoring.
By improving the detectability of low-level microorganisms, chemicals, or particulate contaminants, concentration provides samples better suited to measurement. In wastewater-based epidemiology, this can support surveillance of target microorganisms, while in pollution assessment it helps characterize chemical or particulate contamination. The value of either application depends on preserving the target and retaining representativeness.
