WASTEWATER DISINFECTION APPLICATION NOTES
Disinfection By-Products (DBP) Precursor Monitoring
Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.
Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.
UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.

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
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.

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.
