Wastewater Treatment Case Studies and White Papers

  1. Keep Your Pumps Running Smoothly To Optimize Process Efficiency

    Industrial pumps consume up to 20% of the world’s energy production and can be responsible for 25 to 50% of a process plant’s energy bill, according to Europump, the Hydraulic Institute and other sources. Nothing moves without them in a process plant, and they are expensive to purchase, maintain and even more to repair or replace. Reducing pump lifecycle costs (their purchase, operation and maintenance) is critical in a process plant optimizing efficiency and product output. The process and the surrounding equipment configuration can be responsible for unnecessary high pump lifecycle costs.

  2. 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. 

  3. Odor Control For The City Of Houston

    A supersaturated side-stream process (SDOX-CS®) was successfully deployed at temporary and permanent locations throughout the City of Houston for the effective control of collection system odors. 


  4. Case Study: Continuous Monitoring Safeguards Malaysia’s Water Quality

    Well on the way to becoming a total environmental monitoring solutions provider, Alam Sekitar Malaysia Sdn. Bhd. has applied its expertise in air and water quality monitoring to aid the Malaysian government in safeguarding the nation's water supply. A broad contract between ASMA and Malaysia's Department of the Environment partners the two entities in a highly efficient system that gathers long-term trend data on water quality while also maintaining an early warning system to alert officials and water treatment operators of pollution discharges in key reaches of the country's river system

  5. Coal Yard Runoff Compliance Using Actiflo® Technology

    Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.

  6. ProjectWise’s Geospatial Management Extends Searchability Of Philadelphia Water Documents

    The Philadelphia Water Department (PWD) is a municipal utility providing a population of nearly 1.7 million people in three eastern Pennsylvania counties with integrated water, wastewater, and stormwater services. The utility is responsible for planning, design, construction, operation, and maintenance of the necessary infrastructure.

  7. City Saves Money And Energy With Real-Time Control System

    Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.

  8. Premium Efficient Shaft Grounding Rings VFD Operation

    When a motor is operated on a variable frequency drive, unexpected voltage can be induced on the rotor and shaft.

  9. Harmsco Solutions For Small Community Water Supply

    The Township of Shenandoah, Virginia was forced to comply with new regulations being enforced by the United States EPA concerning the removal of Cryptosporidium and Giardia Cysts from surface waters. Previously, no filtration was required.

  10. Changxing Power Plant Debuts The World’s First Forward Osmosis-Based Zero Liquid Discharge Application

    Desalination Technology Transforms 650 m3/day of Abused Industrial Wastewater
