  • Not All UV Lamps Are Created Equal
    Not All UV Lamps Are Created Equal

    When the Summerville, GA, WWTP was looking to convert from chemical disinfection to UV, staff made the common mistake of purchasing low-price aftermarket lamps to keep costs down. Within eight months, the lamps in the UV system failed to meet expectations for permit requirements, and they had to gain approval for emergency procurement of WEDECO’S ECORAY® lamps as replacements. Today, the plant achieves the required disinfection with a significant reduction in energy use.

WASTEWATER DISINFECTION NEWS

ABOUT WASTEWATER DISINFECTION

 

Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.

A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.  

The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
