Water Resource Recovery Facility Replaces its Aging UV System - Murfreesboro, Tennessee (Case Study)

Significant innovation had occurred in the 17 years since the TrojanUV4000™ was installed at the Murfreesboro Water Resource Recovery Facility. Advancements associated with system efficacy, simplified maintenance, and energy efficiency had been introduced, all of which correlate to cost savings. Such advancements can all be found in the TrojanUVSigna™ – the UV system that was selected for the upgrade.

  • Put An END™ To Silica Fouling
    Put An END™ To Silica Fouling

    Despite the tremendous advancements in water treatment technology over the past several decades, a handful of compounds remain significant challenges.  Among the most challenging for water treatment systems is silica which can lead to irreversible fouling in modern (RO) treatment systems.  Magna Imperio’s new Electrochemical Nano Diffusion (END™) process offers a simple and cost-effective solution for treatment of raw water and brine streams with high silica concentrations.

  • Luxury Resort Chooses AdvanTex® For Its Low Life-Cycle Costs
    Luxury Resort Chooses AdvanTex® For Its Low Life-Cycle Costs

    A new luxury resort was planned for a scenic location just outside the small Greek village of Paliouri. With no municipal sewer available, the investors needed a decentralized wastewater treatment system. The system would have to consistently meet discharge limits, allow for future expansion, and offer low life-cycle costs. Also, it would need to operate with minimal odor or sound, so as to go unnoticed by guests.

  • Addressing Fouling Challenges In Water Treatment With RO Membrane
    Addressing Fouling Challenges In Water Treatment With RO Membrane

    Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

  • Two Products Combine To Provide An Enhanced Nutrient Removal Advantage To Protect Our Waterways
    Two Products Combine To Provide An Enhanced Nutrient Removal Advantage To Protect Our Waterways

    Cherokee County, GA, conducted an extensive on-site pilot evaluation of several available process options and technologies, including various plate settler designs. Read the full case study to learn how enhanced nutrient removal (ENR) integrated design continues to deliver water quality of <0.1 mg/L Ammonia, <0.07 mg/L Phosphorus and <0.5 NTU. Not only does the WWTP consistently meet EPA direct discharge limits on BOD, Total Nitrogen, Phosphorus and Turbidity, but these final effluent values readily exceed surface water discharge permits levels.

    Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed

    The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life — from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA Denite technology is treating 450+ MGD in the Bay.

    Automated Residual Boosting System Improves Chloramine Levels, Eliminates Nitrification In 400,000-gal Tank

    Like many municipalities in urban and suburban areas, San Bruno’s source water comes both from its own groundwater supply and through a purchase agreement with a major water utility — in this case, San Francisco Public Utilities Commission (SFPUC). And, like many municipalities in California, SFPUC, along with San Bruno, switched from free chlorine to chloramines in 2003 largely to reduce disinfection by-products.

  • Packaged Wastewater Treatment For Guantanamo Bay
    Packaged Wastewater Treatment For Guantanamo Bay

    In 2001, with the growing population at Naval Station Guantanamo Bay, and expected future growth, a wastewater treatment system was needed to handle the increase in flows. Fluence worked directly with the United States Navy to design an advanced wastewater treatment plant to meet those needs. The intent was to supply four or five large packaged wastewater treatment systems at different locations around the base.

ABOUT WASTEWATER FILTRATION

Wastewater filtration is often part of the tertiary treatment process that involves the final removal of suspended particles from water that has passed through both the primary and secondary treatment phases and immediately precedes disinfection. As the water passes through the filter, residual suspended material and bacteria is trapped in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Wastewater filtration is usually the final step in the solids removal process.

With regulations increasing around wastewater effluent, the use of ultrafiltration and microfiltration systems in further polishing effluent has grown. Sand or activated carbon filters can provide a media for bacterial decomposition of nutrients, converting nitrates into nitrogen gas. The rise of water reuse applications is also fueling the increasing use of filters during the final polishing stages of the wastewater treatment process.
