Zero Liquid Discharge – Maximum Recovery And Why It Finally Makes Sense
Zero Liquid Discharge – Maximum Recovery And Why It Finally Makes Sense

Our planet continues to become increasingly more crowded.  Pollution and waste are showing irreversible impact on a global scale, and it has become necessary to come up with solutions in all industries.  It is widely known, though perhaps not publicly thought of, that the process of purifying water creates waste.  As we remove the minerals and impurities from water, we inherently condense those impurities into a smaller body of water.  This waste affects the environment in various adverse ways.  The solution lies in a concept known as Zero Liquid Discharge (ZLD).

  • Case Study: Real-time Continuous Nitrate Monitoring Provides A Window On Nutrient Loading In Lake Pontchartrain Louisiana's Lake Pontchartrain Basin lies at the mouth of the Mississippi Delta and squarely in the sights of water quality experts from around the world. The Lake Pontchartrain Basin is an esturarine system that has been significantly disturbed by the construction of the Mississippi River Gulf Outlet in the 1960s as well as agriculture, logging and development in the area. The lake's increasing salinity and shrinking wetlands have garnered significant attention, as has the nitrate-laden water rushing past the basin through the MRGO just below Pontchartrain's southern shore
  • Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue
    Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue

    In order to meet the anticipated effluent criteria required by the Pennsylvania DEP, the Newville Borough Water & Sewer Authority determined that its existing wastewater treatment facility needed renovations. By installing two continuous fill SBR tanks, the facility lowered total nitrogen below permit limits, reduced energy costs, and created a new revenue stream (selling unused nutrient allocations). Read the case study for full details.

  • Removal Of PFCs With Activated Carbon
    Removal Of PFCs With Activated Carbon

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

  • Dissolved Oxygen Measurement In A Wastewater Treatment Plant
    Dissolved Oxygen Measurement In A Wastewater Treatment Plant

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.
