Nutrient Removal Case Studies and White Papers

  1. California Casino Utilizes MBR System For Wastewater Reuse
    8/6/2009

    Quechan Casino Resort, a newly constructed gaming facility located on Native American owned land in Winterhaven, California, began its wastewater treatment operations in January 2009. Early into the project development, it was decided that the Aqua-Aerobic® MBR membrane bioreactor system was the optimum solution due to its small footprint, high-quality effluent and low energy consumption. By Aqua-Aerobic Systems, Inc.

  2. Biothane Delivers Anaerobic Wastewater Treatment To Veryfine Products
    3/17/2009

    Biothane’s turnkey project was designed to treat wastewater by providing a series of treatment processes. Pre-treatment consists of a bar screen, influent sump, grit removal and rotary screen to remove debris from the influent stream.

  3. Case Study: Buxahatchee Chose Aqua Technologies For Its Small Footprint And Ability To Meet Stringent Nitrogen And Phosphorus Requirements
    9/25/2008

    The Buxahatchee Wastewater Treatment Plant in Calera, Alabama was built in 1960. It upgraded in 1985 to a 0.75 MGD capacity extended aeration system with integrated clarifier and traveling aeration bridge for nitrification.

  4. Aqua MSBR® System Meets Phosphorus Removal Requirements In China Without Chemicals
    2/27/2008

    The Shenzhen Yantian WWTP is located in the Shenzhen Economic Development Zone near the Yantian port in China. The plant is partially surrounded by light industrial businesses and small jewelry factories. It occupies 11.5 hectares (28.4 acres) and serves a municipal population of about 125,000 along with the surrounding industrial amd jewelry businesses

  5. Case Study: Warm Springs Replaces RBC System With True Batch AquaSBR® Technology To Meet Effluent Requirements In Limited land Space
    1/10/2008

    Warm Springs Wastewater Treatment Plant (WWTP) was incorporated in 1950 and utilized a RBC system with secondary clarification and chlorine disinfection to meet BOD and TSS treatment objectives

  6. White Paper: Biologically Engineered BioFilm Modifications For The Enhancement Of Collection System Transformations And Impacts On BNR Wastewater Treatment
    12/19/2006
    Increased influent RBCOD and heterotrophic plate counts coincided with the start of bioaugmentation in this study. Observed influent sulfide levels were also lower during bioaugmentation

  8. Case Study: AquaSBR® System Treats High Strength Vegetable Processing Waste
    9/14/2006

    In early 1993, Birds Eye Foods was faced with a difficult decision, to construct a new wastewater treatment facility or to retrofit their existing flow-through extended aeration treatment system

  9. Case Study: First Municipal-Industrial Water Reuse Project In Virginia!
    7/3/2006

    Hampton Roads Sanitation District was created in 1940 to reduce pollution in the Chesapeake Bay. It currently serves a population of approximately 1.6 million with nine regional wastewater treatment plants in Hampton Roads and four smaller plants on Virginia’s Middle Peninsula. HRSD set the goal to reuse its treated wastewater for nonpotable purposes in the 1980s. An oil refinery located next to their York River Treatment Plant approached HRSD in 1996 to supply reclaimed water for the refinery’s cooling and process water. Previously, the refinery utilized increasingly expensive potable water and upgrading its own treatment facilities was too large an investment. In December 2000, HRSD signed a 20-year agreement to provide the refinery with 0.5 MGD of reclaimed water
