  1. Aqua MultiBore® C-Series Ceramic Membrane System Solves Disinfection By-Product (DPB) Challenge At Butte-Silver Bow, Montana

    The Basin Creek Reservoir in Butte, MT served its community with pristine water from both sides of the Continental Divide for nearly 100 years. In 2010, a pine beetle infestation killed most of the trees surrounding the reservoir, many of which fell into the water, increasing the natural organic matter (NOM) level.

  2. Filter Installations Remove Solids From FGD Scrubber Effluent

    Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

  3. Pile Cloth Media Filtration For Clean Utilities

    Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

  4. City Saves Big Money By Using Cloth Media Filters To Treat CSO Discharge

    The City of Rushville, Indiana had to remedy a consent order filed in 2007 for its untreated combined sewer overflow (CSO) discharges that were polluting the Flatrock River, a violation of the Clean Water Act. The city originally planned to install a 1 MGD stormwater storage tank, but was approached by Aqua-Aerobic representatives with a pilot test proposal utilizing a new technology.

  5. Getting A Handle On Sewer Overflows

    Wet weather events are a growing concern for wastewater treatment plant operators, but a new twist on cloth media filtration may provide the answer to their peak flow management problems.

  6. Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants

    Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

  7. Reduce Lifecycle Costs For BNR With A Phased Activated Sludge System

    Many wastewater utilities are under regulatory mandates to reduce effluent nitrogen and phosphorus. When trying to determine the best method for biological nutrient removal (BNR), lifecycle costs are an important factor.

  8. Aqua-Aerobic Systems, Inc. Announces A Partnership With Pinnacle Ozone Solutions, LLC As The Exclusive Municipal Distributor Of Its Ozone Products

    Aqua-Aerobic Systems, Inc. (Loves Park, IL) and Pinnacle Ozone Solutions, LLC (Cocoa, FL) have signed an agreement that confirms Aqua-Aerobic Systems as the exclusive municipal distributor for Pinnacle’s ozone generation systems.

  9. Filtering Through The Latest In Primary Wastewater Treatment

    Of course, the whole wastewater treatment equation starts with primary treatment. Although a critical first step in the process, primary treatment rarely receives as much attention from innovators as processes further down the line. It’s about time that changed.

  10. Aerobic Granular Biomass Technology: Recent Performance Data, Lessons Learnt And Retrofitting Conventional Treatment Infrastructure

    Aerobic granular sludge has been extensively researched over the last two decades as a part of the search for more sustainable wastewater treatment solutions. Conventional activated sludge (CAS) systems have key disadvantages such as slow settling flocculent biomass necessitating large clarifiers and low reactor biomass concentrations (typically 3-5 kgMLSS/m3), large treatment system footprints and relatively high system energy usage. It has been shown at the lab, pilot and the full scale that aerobic granular sludge has distinct advantages, when compared to CAS systems, including improved settling characteristics, which in turn allows for higher biomass concentrations and hence more compact treatment systems.
