Wastewater Filtration Resources

51. BIOSTYR® Improves Health Of The Long Island Sound 6/13/2018

    The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.

52. Bringing An END™ To RO Brine And Difficult Brackish Water Treatment 6/8/2018

    Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21^st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.

53. Put An END™ To Silica Fouling 5/25/2018

    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.

54. Addressing Fouling Challenges In Water Treatment With RO Membrane 4/18/2018

    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.

55. Two Products Combine To Provide An Enhanced Nutrient Removal Advantage To Protect Our Waterways 3/23/2018

    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.

56. Starch Mill Anaerobic & Aerobic WWTP Monitoring Program 12/7/2017

    Over the course of a 1.5-month field experiment at a Canadian starch mill biological wastewater treatment process, LuminUltra Technologies demonstrated the benefits of using 2nd Generation ATP® monitoring technology. ATP (Adenosine Triphosphate) monitoring technology is an accurate biomass measurement that can rapidly monitor all types of biological wastewater treatment processes, aerobic and anaerobic alike.

57. Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed 11/14/2017

    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.

58. Automated Residual Boosting System Improves Chloramine Levels, Eliminates Nitrification In 400,000-gal Tank 7/31/2017

    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.

59. Packaged Wastewater Treatment For Guantanamo Bay 7/28/2017

    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.

60. Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years 6/26/2017

    The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.
