  • Zuser - Polaris 2800 - With Lindner, you know what you’re getting - Case Study

    Zuser Ressourcenmanagement GmbH is not keen on experiments: for the past 24 years the RDF producer in Peggau, Austria has bought shredders made by Lindner Recyclingtech. The new addition to the family is a Polaris 2800. For one-step shredding every other machine was simply out of the question. The cooperation with Lindner dates back to a time before Mag. Georg Zuser became CEO of the Zuser ...

  • 3 Water Utilities that Lowered their Arsenic Levels with AdEdge

    Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the ...

  • Repurposing Composting Infrastructure

    A Vermont solid waste district utilized a defunct biosolids composting site to create capacity for processing food waste. The Vermont legislature instituted a progressive ban on organics in landfills via Act 148 in 2012. The Act includes the provision that transfer stations/drop-off facilities must accept food scraps by July 1, 2017. The Lamoille Regional Solid Waste Management District (LRSWMD) ...

  • Why Interactive Ultrasonic Programs are Important to Effectively Control Algae

    Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively  ...

  • Point of use/point of entry treatment with LFNano

    EconoPure Water Systems EconoPure Water Systems designs and manufactures highly economical, scalable, low‐fouling membrane systems. The Company leverages the proprietary low‐fouling nanofiltration (“LFNano”) system consisting of a unique membrane element that is designed to avoid particulate fouling, biofouling and scaling. As the name suggests, the LFNano utilizes ...

  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • Comparative analysis of two low cost point-of-use water treatment systems

    The study examined two low-cost point-of-use water treatment systems developed in respect of bacterial and particulate removal when exposed to surface water for three months. Bacterial removal efficiency was estimated using E. coli and fecal coliforms, while particulate reduction efficiency was estimated by determining turbidity and total suspended solids (TSS). The systems investigated were ...

  • A compact point-of-use water purification cartridge for household use in developing countries

    Simple, low-cost household interventions are known to be effective in lowering the incidence of waterborne diseases in developing countries. However, high costs along with operational and maintenance issues have prevented the successful adoption of these interventions among the affected communities. To address these limitations, a cost-effective, gravity-driven water purification cartridge has ...

  • Development of point-of-use water disinfection technology using ceramic water filter and electrochemical hybrid system

    The efficiency of water disinfection using a ceramic water filter and electrochemical hybrid system was investigated. Escherichia coli O157:H7 was effectively inactivated even when a storage battery, charged using a solar panel device, was used for the electrolysis process. During electrolysis, the rate of microbial inactivation was higher at higher initial Cl− ...
