  • Surface Water Monitoring - Case Study

    Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which ...

  • Determining flammability of SpillFix Universal Organic Absorbent

    SpillFix Universal Organic Absorbent is an industrial absorbent product made from natural coir (coconut husk). Flammability tests (as detailed below) have determined that the product is a Not Readily Combustible Solid, and is unlikely to catch fire even after absorbing flammable spills. Determining Flammability The tests for determining ...

  • Effects and mechanistic aspects of absorbing organic compounds by coking coal

    Coal is a porous medium and natural absorbent. It can be used for its original purpose after adsorbing organic compounds, its value does not reduce and the pollutants are recycled, and then through systemic circulation of coking wastewater zero emissions can be achieved. Thus, a novel method of industrial organic wastewater treatment using adsorption on coal is introduced. Coking coal was used ...

  • Economics of super absorbent polymers and waste stabilization

    Economics of Super Absorbent Polymers & Waste Stabilization The use of super absorbent polymer (superabsorbent polymer or SAP) in waste stabilization offers many advantages over more conventional absorbents. These advantages include: • Minimal increase in waste volume or weight • Lower transport fees due to less loads • Lower total landfill disposal fees due since waste volume has not ...

  • Organics Monitoring (TOC)

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small. Organic Matter Organic ...

  • Assessment of absorbed dose in digital and MIRD phantoms by MCNP in thorax area

    This paper describes the development of mathematical models, called phantoms, for the assessment of absorbed doses caused by internal radionuclides. In more developed phantoms, anatomical models based upon 3D imaging methods are used. Cross-sectional anatomical models consist of numerous arrays of voxels, each of which individually corresponds to an organ. The digital phantom presented in this ...

  • Optical Assessment of Dissolved Organic Carbon

    Natural organic matter is present in all sources of drinking water. When chlorine is used for drinking-water treatment, a portion of the natural organic matter reacts to form halogenated compounds, referred to as disinfection by-products (DBPs), some of which are regulated by the USEPA due to their health effects. The implementation of stricter drinking-water quality regulations for DBPs has ...

  • Decreased UV absorbance as an indicator of micropollutant removal efficiency in wastewater treated with ozone

    Ozone transforms various organic compounds that absorb light within the UV and visible spectra. UV absorbance can therefore be used to detect the transformation of chemicals during ozonation. In wastewater, decolourisation can be observed after ozonation. This study investigates the correlation of the UV absorbance difference between the ozonation inlet and outlet and the removal efficiency of ...

  • Absorbed dose using a nanoscale ion beam for Bragg peak calibrations

    The proton beam was investigated for cancer cell therapy in the pancreas. Neon ion interaction profiles were compared with the result of the proton beam, which was investigated for nanoscale ion beam interactions. Simulation for the Bragg peak calculation was performed for interactions with a human organ, the pancreas. The results show the absorbed dose and dose equivalent, which vary with the ...

  • Monte Carlo studies of the eyelid's influence on the absorbed dose in eye tissues

    The aim of this work was to investigate the influence of the eyelid on the absorbed dose distribution in eye tissues. The study was performed using two versions of the female adult head phantom (FeH) connected to the GEANT4 Monte Carlo code: one has the eyes open and the second, closed. The calculations of organ dose, normalised to air KERMA free-in-air, were done for external exposures to photon ...

  • Characterisation of dissolved organic matter in the Lower Kinabatangan River, Sabah, Malaysia

    Spatial patterns and trends in the concentration and quality of dissolved organic matter (DOM) are characterised across a tropical agricultural catchment using ultraviolet (UV)-visible absorbance, and fluorescence spectroscopy. Related determination of the environmental isotopes 18O and 2H clarify the dynamics of catchment water movement. Water samples were collected from the ...

  • Natural radionuclides in Niger delta sedimentary organic rock samples

    Thirty sedimentary organic rock samples were collected at different depths from three oil wells in the Niger Delta. The natural radionuclides in the samples were measured in order to determine their geochemical significance and radiological effect. The radionuclides were measured using gamma spectrometric technique. Natural occurring radionuclides identified were uranium, thorium and potassium. ...

  • Organic micropollutant removal from groundwater: comparison of pellet softening and nanofiltration

    This study investigated the fate of selected pharmaceuticals and estrogens and the characteristics of bulk organic matter during pellet softening and proposed a possible hybridization with nanofiltration (NF) treatment. A groundwater softening system called pellet softening was used to remove calcium ions from groundwater by crystallizing calcium carbonate on the surface of sand grains that ...

  • Characteristics of natural organic matter and formation of chlorination by-products at Masaka waterworks

    To minimise the formation of chlorination by-products (CBPs) it is imperative that attention is directed towards the structure and occurrence of natural organic matter (NOM) in raw water sources, and its flow and fate during water treatment processes. In this study, an assessment of the characteristics and flow of NOM along the treatment train at the full scale treatment plant at Masaka, Uganda, ...

  • Advanced treatment of petrochemical secondary effluent by Fenton: performance and organics removal characteristics

    The Fenton process was used to treat petrochemical secondary effluent. The effects of initial pH, H2O2, and FeSO4·7H2O dosages on chemical oxygen demand (COD) removal, the dissolved organic matter (DOM) removal and the transformation and migration of typical organic matters during the treatment process were investigated. The results showed that the optimum ...

  • Removal of nitrogen and carbon organic matter by chitosan and aluminium sulphate

    River and lake waters were separated into four fractions to study the removal of nitrogen and carbon organic matter using chitosan (CH) and aluminium sulphate (AS). The fractions were very hydrophobic acid, slightly hydrophobic acid, charged hydrophilic acid and neutral hydrophilic. The results showed that the whole and fractionated water from both sources have a markedly hydrophobic character. ...
