  • Using Nanofiltration in Beverage Production

    The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...

  • Toxic dissolved and dispersed hydrocarbon removal in industrial wastewater and groundwater treatment and reuse with the Macro Porous Polymer Extraction Technology

    Abstract The trend to more severe discharge requirements and to polluted groundwater treatment pushed by governments and followed by industries goes together with the development of more advanced water treatment technologies. Nowadays these requirements have gained such high standards that one step further to contaminated water reuse becomes attractive, especially in areas where fresh water ...

  • Municipality of Barrows, Manitoba case study

    Situated some 500 km north of Winnipeg, the municipality of Barrows is home to about 300 inhabitants. Barrows has a school in the village with close to 100 students. The only available source of water supply for the municipality is an underground spring with a TDS (total dissolved solids) concentration exceeding 1900 mg/L making the water undrinkable (see Table I). At the request of John Brittain ...
