Wastewater Treatment Insights

  1. Global Experts Offer 2019 Smart Water Insights
    2/13/2019

    What are some of the biggest global challenges, trends, and opportunities for the smart water sector in 2019? To answer these questions, the Smart Water Networks Forum (SWAN) interviewed four industry experts from Australia, North America, the UK, and India.

  2. Design And Care Of Reverse Osmosis Systems, Part 3: Operation And Monitoring
    2/5/2019

    Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.

  3. On Site But Out Of Mind… Getting Extra Mileage Out Of Your Disinfection System
    1/31/2019

    Using on-site sodium hypochlorite generation technology to make oxidant for water and wastewater treatment is cost-effective, safe, and environmentally responsible. But, as with any piece of equipment, choosing the right one and caring for it properly impacts both life cycle costs and effectiveness. We talked with David McWalters, Field Service Manager-Americas, De Nora, to learn more.

  4. Is A Containerized Treatment System Right For You?
    1/24/2019

    As industrial facilities continually look for ways to reduce capital costs and decrease installation timelines associated with water treatment and other systems, the practice of containerizing equipment has become more prevalent. A containerized system offers many benefits of lower costs than comparable field erected buildings, faster timelines, and lower field installation requirements. 

  5. Aerobic Treatment Unit (ATU) System Design Tips And Operations Variables
    1/23/2019

    Providing a suitable environment for microorganisms to treat wastewater is what aerobic treatment units (ATUs) are all about. These advanced systems outshine alternatives on tight lots where there is no room for conventional treatment and on sites with poor soils, shallow vertical separation distances to limiting conditions, and horizontal setback restrictions. Some systems can be designed for the treatment of high-strength wastewater or where total nitrogen removal is required.

  6. Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment
    1/14/2019

    The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

  7. The Role Of IoT And Control Technologies In Water Filtration Systems
    1/10/2019

    With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.

  8. EPA-New Mexico Wastewater Report Is A Conversation Starter, Not The Final Word
    1/4/2019

    When it comes to answering questions about whether the oil and gas industry’s wastewater can be safely reused for other purposes, like food crops, livestock, or even drinking water, there are a number of other serious factors to be considered.

  9. Understanding And Coping With Struvite/Vivianite Formation In WWTPs
    12/21/2018

    Based on wastewater properties, various types of mineral buildup can affect wastewater treatment plant (WWTP) piping. With their impacts on plant energy efficiency and potential restriction of throughput capacity, keeping pipes free-flowing is an important aspect of WWTP operations. Here’s guidance for coping with two common problems associated with phosphorus concentrations in wastewater — struvite and vivianite.

  10. Design And Care Of Reverse Osmosis Systems, Part 1: Design
    12/20/2018

    Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.
