How does everyone achieve effluent water that meets their needs and demands? Each situation is different, but a simplistic explanation of various technologies will be discussed in this article. Each of the following categories has had much written about them, but this article will be an overview of several methods in order to help you educate the general public so they can make an intelligent decision, purchase something of value and continually seek professional consultation.
Brushing up on water treatment 101
Basic water chemistry, terminology and applications can be very complicated and not seem so basic to individuals without a chemistry background. This series of articles will help shed light on the chemistry of water and the mysteries that it can contain, plus explain the technologies used to treat water so the purchaser can make an educated attempt to find the right solution for a particular application. There are no cut-and-dry formulas for water treatment and certainly no cure-all for every application or problem, but with an understanding of how water works and the technologies developed to treat water, a person can utilize his resources to come up with solutions for his particular need or application.
Brushing Up on Water Chemistry 101
Historically, industry has relied on hazardous chemicals such as chlorine and expensive processes such as pasteurization to rid its water supplies of pathogens. Currently, though, the use of ultraviolet (UV) light, the same as the portion of the electromagnetic spectrum of sunlight responsible for killing microorganisms, is providing a safe, reliable and highly effective method of getting the job done.
The science, selection and applications
Security measures do exist to safeguard our public water supply. Utilities routinely employ techniques such as chlorination, filtration, and ultraviolet treatment, to name a few. However, given the changes that have taken place in the world since September 11, 2001, the prospect for intentional contamination seems more possible than ever before. We want to have confidence that our existing security measures and analytics are adequate but with so many possibilities, how can we?
System developed for UK military now available to water companies in America
If our water supplies actually do come under attack, the question remains: Is there any way for consumers to protect themselves? Unfortunately, it seems to be too early to tell, yet some companies are beginning to emerge with products that may be the answer.
Can POU/POE technology aid the war on bioterrorism?
UV is an accepted and rapidly growing technology for treating wastewater in the United States. In Europe, it commonly is used as a primary disinfectant in municipal drinking water systems. Other applications include food and beverage, pharmaceutical, semiconductor and power generation. This article will discuss three other commercially successful and growing applications.
Successful Ultraviolet for Commercial Applications
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.
