  • CombiFlash Gradient Methods

    Abstract Purifying compounds require two processes: the actual purification and drying the sample afterwards. Several gradient methods were evaluated on a reaction mixture to evaluate run time and number of fractions to collect the desired compound. Reducing the volume of fractions is important to reduce the time required to dry the purified material. On large runs, drying time may be ...

  • Dissolved Solids and Water Purification

    To make drinking water palatable, the level of dissolved substances (TDS) can’t be too high, but it also can’t be too low Water quality metrics are needed to ensure that surface and groundwater – common sources of water for human consumption – are free from contaminants and pollutants. The level of dissolved solids, also commonly referred to as total ...

  • Measurement of oxygen during the purification of glycerin – Case Study

    Background information Glycerin is a basic chemical which is used in creams and ointments, in antifreeze and brake fluid for vehicles, as a plasticizer, and as a base for paints and lacquers. Glycerin is produced as a by-product during the manufacture of soap. This was the main source of glycerin for many years. However, the production of biodiesel has increased greatly in the last ...

  • Why is drinking water treatment necessary?

    Water is found in ample amount almost everywhere on earth. The natural water resources such as lakes, rivers, etc. that provide water contain a lot of pollution, garbage which is unfit for human consumption. To clean the water, it should undergo numerous water treatment media procedures that make it suitable to drink. The water ...

  • How water scarcity in industry can be prevented?

    Growing urbanization and industrialization has resulted in water scarcity across the world! For the growing population and scaling living standard consumption of water is rising up. Rising water scarcity does have a negative impact on the industrial productions. This can develop crisis for the industries and would impact on economical development. Several industries even do have noticeable ...

  • Methods of Purification by Water Innovations, Inc.

    Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. ...

  • 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 ...

  • Comparison of the water purification efficiency of two different flocculation-sediment-filtration (FSF) processes in Chaohu Lake in China

    A novel biofilter (BF) with the potential to improve pollutant removal when used as a substitute for sand filters in water purification processes is presented. To investigate BF's pollutant removal performance, a flocculation-sediment-biofiltration (FSBF) process was compared with a flocculation-sediment-sand filtration (FSSF) process on a lab scale, with water collected from Chaohu Lake. The ...

  • Direct potable reuse – a feasible water management option

    Direct potable reuse (DPR) can be more economic than indirect potable reuse as no environmental buffer is needed and conveyance and blending of the purified water with other potable sources is basically less expensive. Long-term experience in Windhoek (48 years) shows that treated domestic sewage can be safely and cost-efficiently utilized for potable reclamation (0.72 €/m3). A multiple ...

  • Novel thermoresponsive assemblies of co-grafted natural and synthetic polymers for water purification

    Water contamination and its purification are a global problem. The current approach to purify water is reduction of impurities to acceptable levels. One of the ways to achieve this is by use of water-soluble polymers that extract organic and metallic contaminants, from water. This paper presents a blend of composite polymers that eliminates both the contaminants simultaneously by the principle ...
