SDOX TREATS RETENTION POND

UNIVERSITY OF ARKANSAS TECHNOLOGY PARK

 

Technology: SDOX

Application: Aeration

Location: Arkansas

Owner: UA Technology Development Foundation

Engineer: Larry Linguist

Goals: Prevent Odor Complaints | Control Nutrient Levels 

 

INTRODUCTION

In May 2010, officials at the University of Arkansas Technology Development Foundation were in need of a cost-effective method of preventing the formation of odor-causing compounds and controlling nutrient levels in a retention pond near their facility. In order to accomplish this task, tech park officials elected to inject the pond with dissolved oxygen (DO) to maintain insolubility and facilitate biological treatment of nitrogen.

 

METHOD

BlueInGreen’s SDOX® technology operates more effectively than traditional DO delivery systems, recording oxygen transfer efficiency rates of up to 98%. By injecting a sidestream into a pressurized oxygen tank, the SDOX saturates the water, resulting in concentrations of nearly 350 mg/L. The highly oxygenated sidestream is then returned to the larger body of water, where rapid liquid-to-liquid mixing of the sidestream occurs. The rapid diffusion of the liquid ensures consistent delivery of DO, limiting nutrients and stopping odor issues as the source.

 

THE SDOX OPERATES MORE EFFICIENTLY THAN TRADITIONAL DO DELIVERY SYSTEMS, RECORDING OXYGEN TRANSFER EFFICIENCY RATES OF UP TO 98%.

 

RESULTS

With the help of the SDOX, the water quality in the retention pond improved significantly. The incoming DO provided a better habitat for aquatic life and even provided efficient treatment for runoff. When compared to competing dissolution systems, the tech park reduced power consumption and other operational costs by implementing the SDOX, while minimizing the equipment footprint.

 
 

OFFICIALS AT THE UNIVERSITY OF ARKANSAS TECHNOLOGY DEVELOPMENT FOUNDATION WERE ABLE TO PREVENT ODOR COMPLAINTS, CONTROL NUTRIENT LEVELS AND MAINTAIN DO LEVELS AT A FRACTION OF THE COST.

 

CONCLUSION

The SDOX met all short term goals by controlling the retention pond’s water quality despite unnatural organic loading into the system, caused by pollution. Because of BlueInGreen’s dissolution system, officials at the University of Arkansas Technology Development Foundation were able to prevent odor complaints, control nutrient levels and maintain DO levels at a fraction of the cost.
