Wastewater treatment is indispensable as wastewater can lead to adverse health effects and deteriorate the quality of life on earth. Photocatalysis a facile methodology address this issue. In study, nanocomposites (NCs) manganese oxide (Mn3O4) nickel (NiO) were synthesized in different weight ratios via solid-state reaction route. Structural properties, optical surface morphology, functional gr...

Sorption is currently a promising method for purifying wastewater from organic and inorganic substances. The authors have developed technology obtaining granular composite sorbent (GCS), on the basis of large-tonnage production waste - tobacco dust. However, as result sorption purification highly concentrated food industry enterprises, significant amount formed, regeneration which economically ...

In the last decades, membrane processes have gained a significant share of the market for wastewater purification. Although the product (i.e., purified water) is not of high added value, these processes are feasible both technically and from an economic point of view, provided the flux is relatively high and that membrane fouling is strongly inhibited. By controlling membrane fouling, the membr...

Abstract In recent years, non-thermal plasma technology has gained considerable attention. It can produce highly reactive hydroxyl radicals and other strong oxidants, which is promising in environment pollutants removal. This article mainly reviews the advances contaminants removal with several well-known technologies. We first introduce its development, then summarize their applications for ai...

Abstract In recent years, the leakage of crude oil and discharge oily wastewater in industrial production have seriously endangered water environment ecological safety. Adsorbent materials with excellent oil-water separation performance play an important role purification. this work, we employed a simple yet effective strategy to prepare highly compressible wood sponges. And prepared sponge as ...

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...

Wastewater treatment process aims at achieve the purpose of purification by degradation of organic matter in water. To ensure the effluent water quality, some indicators should be measured, including chemical oxygen demand (COD), Biochemical oxygen demand (BOD), etc. Through the prediction on effluent indicators can provide effective guidance for the operation of wastewater treatment plant. Was...
