Reclaiming water in the greenhouse industry will soon be something the government will be mandating the growers in the industry to do, as more wells are becoming contaminated from nitrates and phosphorus levels are becoming a concern for public health.
Copper Ionization, Ozone Provide Effective Pythium Treatment
While UV disinfection is an effective way to deliver microbiologically safe water, understanding local regulations for its use can be more complicated than understanding how UV scrambles a microorganism’s DNA.
Unraveling Local Regulations
In past articles, we discussed the benefits of ultraviolet (UV) disinfection as well as the many available options. In this article, we will focus on the available technologies and provide an overview of how these technologies are being applied in commercial and industrial applications.
Available technologies and their use in C&I applications
In the last issue, we reviewed ultraviolet (UV) disinfection as a suitable technology for treating biologically unsafe water supplies. In this article, we will focus on system design and understanding the many available options for residential and commercial applications.
Understanding Residential and Commerical UV
The benefits of ultraviolet (UV) light in destroying waterborne diseases are well established. This article (part one in a continuing series) will focus on explaining the basic terminology associated with the technology.
Understanding Ultraviolet Terminology
This article offers a method for comparing the results of a UV pilot system with a full-scale UV system.
These profiles of various disinfection processes can help managers decide which process is best suited for their treatment plant.
Managers of water treatment plants must be able to choose the right disinfection system to bring their plants into compliance with government regulations.
The application of disinfectants in drinking water treatment for controlling microbial quality has drawbacks. These include the formation of potentially harmful disinfection byproducts (DBPs) that can be potential carcinogens (e.g., trihalomethanes [THMs] when chlorine is used as a disinfectant). The general equation is:
ÊÊÊNOM + Disinfectant -> DBP
ÊÊÊWhere NOM = Natural Organic Matter
