The unique process features of the AquaNereda technology translate into a flexible and compact process that offers energy efficiency and significantly lower chemical consumption.

  3. AquaSBR® Sequencing Batch Reactor 10/11/2024

    The AquaSBR®sequencing batch reactor provides true batch reactor technology with all phases of biological treatment accomplished in a single reactor. All components are easily accessible and the advanced decant system ensures optimum quality effluent withdrawal.

  4. Nutrient Removal 6/28/2024

    Phosphorus and nitrogen, while necessary elements for life, when concentrated in the effluent of a wastewater treatment plant, are harmful to the environment, especially aquatic plants and animals. When concentrated amounts of these elements enter bodies of water, it causes algae blooms, which reduces dissolved oxygen in the water and can be damaging to animal populations. It can be a very serious problem for natural areas downstream of industrial or municipal discharge.

  5. PRI-CEPT® Phosphorus Removal From Wastewater 6/28/2024

    When applied to plant influents, hydrogen peroxide destroys dissolved and/or total sulfide that otherwise scavenges Fe3+ added for CEPT and/or chemical phosphorus removal from wastewater. The foundational aspect of this PRI-TECH application (called PRI-CEPT) is that one lb of total sulfide theoretically consumes 3.5 lbs Fe3+ and thus represents an additional cost of $2 – 3 per lb influent sulfide.

  6. PRI-TECH® Peroxide Regenerated Iron Technology 6/28/2024

    PRI-TECH® is a combination treatment that integrates iron salts with hydrogen peroxide in a unique and synergistic fashion. The results are both cost savings and treatment enhancement compared to using iron salts alone.

  7. Monitoring IWW Effluents With FP 360 sc Oil-In-Water Sensor 5/14/2024

    This application note explores a test which demonstrated significant improvements in Oil-in-Water monitoring of industrial wastewater in comparison to the weekly grab sample analysis method.

  8. AquaSBR Sequencing Batch Reactor: Food And Beverage Industry 12/6/2023

    This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

  9. Phosphorus Removal And Recovery 3/2/2023

    Discover how you can meet stringent phosphorus limits with solutions that contribute to a future circular economy. 

  10. Continuously Sequencing Reactor 5/6/2021

    The Continuously Sequencing Reactor is a Biological Nutrient Removal (BNR) system utilizing continuous flow in a single basin. It sequences through the 3 process phases required for BNR – Oxic, Anoxic and Anaerobic – in one basin. The 3 phases do not occur at the same time in the basin. They occur sequentially – one after the other, repetitively, over time. During the Oxic phase, the entire basin is Oxic (i.e. aerobic).
