    Reverse Osmosis Water Testing

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important...

    Analysis of VOC compounds in water by Purge & Trap or dynamic headspace

    Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA –...

    Bromate analysis for the drinking water industry

    Bromate forms during the ozonization of drinking water. Several international standards stipulate detection limits and test methods. Conductivity detection with chemical suppression allows the determination of bromate in the lower μg/L range. In the ng/L range, bromate can be detected by IC/MS coupling or post-column derivatization with potassium iodide and subsequent UV detection.

    ADVANCEES - Iron Removal Application - Custom skid-mounted water purification equipments

    Processes for the removal of iron must be approached with an understanding of the water source, iron and manganese concentration, chemical form, and any additional contaminants or species that require removal. In addition, the end use of the water must be considered to determine what level of treatment is required and whether iron and manganese removal should be considered as a treatment step preceding other water purification methods.

    Biological processes for potable water treatment industry

    Removing Organic and Nitrogen Pollution: We all need water to survive. Yet there are many pollutants reducing the quality of the available resources. ENEXIO products are an indispensable part of many processes applied for the removal of those pollutants from the water. Surface water can be polluted by agricultural, industrial or municipal discharges of nitrogen (ammonia or nitrate) or even organic components. For the removal of these components biological processes are a valuable option – also for potable...

    Water Treatment Solutions for Iron & Manganese Removal

    For treatment of Iron & Manganese removal, AdEdge Technologies uses our AD26 or ADGS+ media coagulation filtration with ferric chloride as the coagulation agent. This process allows significantly higher flow rates per square feet of media, less backwash water than other conventional approaches, and smaller footprint systems which means lower capital and operating costs. There are no hazardous chemicals or waste involved and the systems may be automated which decreases operator involvement and expense.
