1. Fluence Is Changing The Economics And Accessibility Of Wastewater Treatment

    Surrounded by agricultural fields where water is a vital resource, the rural region of Hayogev, Israel chose Fluence’s energy-efficient Membrane Aerated Biofilm Reactor (MABR) solution for wastewater treatment suitable for reuse.

  2. Looking For Consistent Aeration Performance Over Time? Consider Jet Aeration

    The VariOx jet aeration system is an aeration and mixing device used in numerous water and wastewater treatment applications. The jet aerator consists of an inner liquid nozzle and outer air nozzle. Liquid from the tank is recirculated through the inner nozzle at a high velocity. Concurrently, air is fed into the outer nozzle where it is combined with the high velocity liquid from the inner nozzle and discharged as a high energy plume.

  3. Innovative New Air / Gas Thermal Flow Meter Changes The Rules

    The decisions and ROI calculations get even more complex when plant staff and their engineering partners are constrained by or must factor in obsolescence should the plant want to consider upgrading their process systems’ communication method. 

  4. Jet Aeration Systems: A Tool For Improved SBR Operation

    Sequencing Batch Reactors (SBRs) are a variation of the activated sludge process that combine treatment steps into a single basin. Based on a fill-and-draw method, major phases of the SBR process include a cycle of fill (with or without aeration), react, settle, decant, and idle. Today, successful flow control strategies have made SBRs state-of-the-art technology. SBRs are commonly used today and are especially beneficial for many industrial applications.

  5. MABR Is The Big Cheese For This Dairy Farming WWTP

    Hayogev is a residential development in the rural area of Jezreel Valley, with 1000 homes, agricultural fields and dairy farms. Located in an open field next to small farms, the local treatment facility handles wastewater from HaYogev and Midrach Oz. The customer was looking for a localized wastewater treatment solution to replace the existing pond system, which faced difficulties in treating the wastewater due to high levels of nutrients. A new state-level regulation concerning reclaimed water required the wastewater treatment plant (WWTP) operator to reduce the nutrients in the effluent stream. The solution had to be odorless and quiet, have low power consumption, and use the existing pond and structure.

  6. What Is The Connection Between Reclaimed Water, Agriculture, And Filtration?

    The case for using reclaimed water is strong. Water has become an increasingly valuable (and often rare) resource, and every drop counts. As potable water sources become harder to find and access, people are moving to alternative sources such as non-potable fresh water, brackish sources, or reclaiming treated effluent rather than disposing of it.

  7. Emerging Trends In Disinfection: Peracetic Acid

    As regulations on chlorinated disinfection byproducts and total residual chlorine become increasingly stringent, peracetic acid (PAA) is gaining in both interest and usage as a water reclamation disinfectant. Here’s what you need to know.

  8. A 'SWIFT' Approach To Managed Aquifer Recharge

    The Sustainable Water Initiative for Tomorrow (SWIFT) will not only restore declining levels to the Potomac Aquifer System, but it will also reduce nutrient discharges to the Chesapeake Bay.

  9. Tackling Modern Wastewater Treatment Challenges And Unlocking Efficiencies With Advanced Water Technologies

    Research studies, empirical evidence, and the march of time all suggest that the implementation of next-generation technologies at wastewater utilities is profoundly important, if not imperative, for efficient operations.

  10. Delivering Assets And Strengthening Communities: A CBP3 Primer

    Local government can harness the power of community-based, public-private partnerships (CBP3s) to efficiently implement programs that encompass delivery of many unique assets — such as stormwater management programs that include green infrastructure. Can your community benefit from this delivery approach?
