Disinfection Performance Testing Of High-Efficiency Ultraviolet Water Treatment Chamber
This is the second in a series of three white papers describing the design and performance of the NeoTech Aqua ReFlex™ treatment chamber. The first describes in detail the theoretical basis for the very high efficiency demonstrated by the chamber. The third paper describes how this chamber design leads to some highly desirable operational advantages beyond just energy ad cost reduction. By J. R. Cooper, Ph. D. and Gwynne Cavender, NeoTech Aqua Solutions, Inc.

Removal of Metaldehyde & Environmental Contaminant Treatment - Lincoln, United Kingdom (Case Study)
Anglian Water (Anglian) is one of the largest suppliers of drinking water and wastewater services in the United Kingdom. As an alternative to ozone, Anglian decided to install a TrojanUVTorrent™ECT UV-oxidation system, as part of a multi-barrier approach, to ensure it produced a potable water supply that matched the high standards required by its regulators and customers.
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.
Genuine TrojanUV3000Plus Lamps Vs. Non-Genuine Lamps: A Side-By-Side Comparison (Case Study)
Perform Lamp Output And Aging Study On Trojan UV3000™ Lamps And Non-Genuine G64T5 Low Pressure UV Lamps
Top 10 Considerations When Converting To On-Site Hypochlorite
Transporting pure salt - the raw material needed to generate sodium hypochlorite onsite – is more cost effective, stable, and safer, than transporting and storing bulk sodium hypochlorite, or gaseous/liquid chlorine cylinders from local chemical suppliers. The conversion to on-site hypochlorite generation can be achieved by adhering to these design guidelines.
Conversion To UV Disinfection: A Natural Wastewater Treatment Alternative
The city of Auburn, AL has two wastewater treatment facilities – the Northside Water Pollution Control Facility and the H.C. Morgan Water Pollution Control Facility. In 2012, the H.C. Morgan facility was upgraded, and disinfection was converted from chlorine to UV. This case study will provide you with details about the selection process, why our TrojanUVSigna™ was chosen, and how we helped simplified the conversion from chlorine.
Size Your Ozone System In 5 Minutes Or Less
The most common questions about using ozone for the treatment of industrial wastewater relate to system sizing and pricing. Here are five quick rules of thumb to get a ‘ballpark size’ for your next ozone project.
Municipal Wastewater Reuse – The Challenges Ahead
Water resources are becoming more constrained. Obtaining surface or groundwater withdrawal permits is becoming increasing difficult. By Randy Turner, Technical Director, Swan Analytical USA
Orenco Systems® Inc. (Orenco) recently completed the sale and commissioning of a wastewater treatment system for the Soyo Municipal Hospital in Angola.

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.
