Florida WWTP Expansion Plays Important Role In Ecosystem Recovery And Protection

Panama City Beach is situated on 27 miles of white-sand beaches in the panhandle of Northwest Florida.  The city is ecologically significant in that it is surrounded by thousands of acres of protected wetlands which are part of the West Bay Ecosystem.

    Ozone has been a proven effective method of water treatment and disinfection for well over a century.

  • Submersible Aerators Blast Off At Naval Air Station WWTP
    Submersible Aerators Blast Off At Naval Air Station WWTP

    When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to RWL Water. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.

  • Case Study: First Municipal-Industrial Water Reuse Project In Virginia!
    Case Study: First Municipal-Industrial Water Reuse Project In Virginia! 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

WASTEWATER APPLICATION NOTES

  • Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day. By YSI
  • Dissolved Oxygen Measurement In A Wastewater Treatment Plant
    Dissolved Oxygen Measurement In A Wastewater Treatment Plant

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.
