  • The Best Ground Water Treatment Methods

    Many homes and businesses depend on ground water or surface water as a vital water source. Unfortunately, much of this water has not been filtered through municipal water treatment and distribution technology. This means that the water many people consume, cook with, and use for basic hygiene can contain potentially harmful particles, including pathogens, tiny organic matter, sediment, ...

  • Forecasting of UV-Vis absorbance time series using artificial neural networks combined with principal component analysis

    This work proposes a methodology for the forecasting of online water quality data provided by UV-Vis spectrometry. Therefore, a combination of principal component analysis (PCA) to reduce the dimensionality of a data set and artificial neural networks (ANNs) for forecasting purposes was used. The results obtained were compared with those obtained by using discrete Fourier transform (DFT). The ...

  • Importance of measuring UV transmittance (UVT) for UV disinfection

    UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm. UV Disinfection Dose and UV Transmittance (UVT) The effectiveness of a UV disinfection system is ...

  • Importance of Measuring UV Transmittance for UV Disinfection

    UV disinfection systems disinfect water using UV light at the 254nm wavelegnth. UV light at this wavelegnth actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as crytosporidium and e-coli from reproducing and causing harm. Real Tech has several products that are commonly used to ensure the correct operation and performance of UV disinfection ...

  • Enhancement of photocatalytic degradation of furfural and acetophenone in water media using nano-TiO2-SiO2 deposited on cementitious materials

    In the present study, silicon dioxide (SiO2) nanoparticles were loaded to titanium dioxide (TiO2) nano-particles by sol-gel method to make a high porosity photocatalyst nano-hybrid. These photocatalysts were synthesized using titanium tetrachloride and tetraethyl orthosilicate as titanium and silicon sources, respectively, and characterized by X-ray powder diffraction (XRD) and scanning ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Removal of naphthalene from offshore produced water through immobilized nano-TiO2 aided photo-oxidation

    In order to increase the applicability of photocatalysis in treating offshore produced water (OPW), an immobilized catalyst was introduced into the UV irradiation system and its performance on the degradation of organic compounds in OPW was evaluated. Naphthalene was selected as the target pollutant owing to its abundance in produced water and its chemical property as a typical polycyclic ...
