WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  • The Importance Of pH Measurement During Industrial Treatment
    The Importance Of pH Measurement During Industrial Treatment

    Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.

  • Sending Your Wet Weather Problem Back To The Cloud(s)
    Sending Your Wet Weather Problem Back To The Cloud(s)

    Most of us don’t have to think about the vital infrastructure that supports our society.  Water is delivered to our homes and businesses 24/7, and wastewater is efficiently and cleanly whisked away.  The ability of our utilities to manage these services means we only take notice at times of inconvenience: water outages, sewer blockages, or stormwater overflows. 

  • Oxygen Removal From The Feedwater Of A Central District Heating System
    Oxygen Removal From The Feedwater Of A Central District Heating System

    Central district heating systems have gained attention in recent years because they can be more efficient than localized boiler units. The efficiency of district heating is usually due to power generation plants being able to produce heat and electricity simultaneously. District heating also helps prevent pollution by using advanced flue gas cleaning techniques.

  • Power Plant Uses Membrane Contactors To Remove CO<sub>2</sub> From Water
    Power Plant Uses Membrane Contactors To Remove CO2 From Water

    A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO2 inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO2 to reduce the load on the equipment and improve the water quality.

  • How To Utilize pH Neutralization Systems And Adhere To Discharge Regulations
    How To Utilize pH Neutralization Systems And Adhere To Discharge Regulations

    For any drinking water or wastewater treatment operation, pH neutralization is never far from top-of-mind. The regulatory standards for pH to which effluent must adhere, also known as “pH neutralization,” are central to ensuring that treatment is performed accurately and that the water or wastewater leaving a plant is safe.

  • Pure Oxygen Injection Into A Pipeline
    Pure Oxygen Injection Into A Pipeline

    The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

  • Wastewater Plant In Como, Italy, Upgrades To De Nora Ozone For Significant Savings
    Wastewater Plant In Como, Italy, Upgrades To De Nora Ozone For Significant Savings

    The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

  • How Data And Nature Can Combine To Help Small Wastewater Treatment Plants Address Huge Hauling Costs
    How Data And Nature Can Combine To Help Small Wastewater Treatment Plants Address Huge Hauling Costs

    It is no secret that the number of landfills has been steadily decreasing across the United States. As more and more cities adopt ‘zero waste to landfill’ sustainability goals, the number of landfills has shrunk from 6,326 in 1990 to 1,738 in 2015. Decreasing landfills has meant increased waste hauling costs for wastewater treatment plants (WWTPs) as sludge travels farther distances to reach landfills.

  • Stokes' Law and How Inclined Plate Settlers (Lamellas) Work
    Stokes' Law and How Inclined Plate Settlers (Lamellas) Work

    In this video, we discuss the curious science that is the inclined plate settler (also known as a Lamella). The process is a bit counter-intuitive, but through an interesting experiment, this video shows how they work. Inclined plate settlers can reduce required footprint by 80% compared to traditional gravity settling.

  • FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey
    FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey

    Despite the destruction of Hurricane Harvey in August 2017, Duperon® wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake® bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.

    DC Water’s Unconventional Approach To Utility Management

    Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

  • Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency
    Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency

    California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
