Biosludge is a by-product of secondary wastewater treatment processes. Due to its high contents of organic carbon and plant nutrients, this bioresource can be practically reused as raw feedstock for making organic fertilizers and building materials. The objective of this paper was to provide a preliminary analysis of biosludge utilization in Taiwan, including food processing sludge, wine brewer...

Microalgae are a promising alternative for sustainable biofuel production, but production yields and costs present a significant bottleneck. Here, the use of glycerol and xylose to boost the lipid yield was evaluated using ten strains from the Université de Montréal collection of microalgae. This report shows that some microalgal strains are capable of mixotrophic and heterotrophic growth on xy...

Kraft pulp mill effluents contain elevated concentrations of resin acids, chiefly abietic and dehydroabietic acid, and other lipophilic wood constituents. Resin acids, if not efficiently removed during wastewater treatment, can be responsible for chronic toxicity in aquatic systems. The objective of this study was to investigate the biological removal of abietic acid (AbA) during the treatment ...

Four wastewater samples of different treatment qualities; untreated, alarm, alert and normal, from a Swedish chemi-thermo-mechanical pulp mill and pure water were investigated using an amperometric bio-electronic tongue in a batch cell. The aim was to explore enzymatically modified screen-printed amperometric sensors for the discrimination of wastewater quality and to counteract the inherent dr...

The present study was conducted in order to investigate the efficiency of different advanced oxidation processes both individually and combination with biological method for removal color chemical oxygen demand (COD) from wastewater pulp paper industry. Advanced include ozone, Fenton, hydrogen peroxide, photo-Fenton. Biologically treated successively subjected (AOPs). optimum conditions ozone t...

Erratum: “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” The Focus article “Radionuclides in Fracking Wastewater: Managing a Toxic Blend” [Environ Health Perspect 122:A50–A55 (2014); http://dx.doi.org/10.1289/ehp.122-A50] incorrectly stated that Pennsylvania requires pit liners for temporary impoundments and disposal to have a minimum thickness of 30 mm. The correct minimum thick...

Colloidal chemistry is a science to study the physicochemical properties of generalized colloidal dispersion systems. Polymer new comprehensive subject that studies synthesis, chemical reaction, physical chemistry, physics, processing and application polymer compounds. The development mainly experienced four periods: utilization natural polymers, modification production synthetic polymers estab...
