Ultraviolet Dechlorination Technology

At the Procter & Gamble manufacturing plant in Greensboro, N.C., an Aquionics ultraviolet (UV) dechlorination unit was installed before two banks of reverse osmosis (RO) membranes. Trials that ran soon after the UV system’s installation showed a dramatic reduction in the RO membrane wash frequency—down from an average of eight cleanings per month to only two per month.

Developments in Ozone Technology

Ozone technology developments have opened new applications for these established water treatment technologies. Driving these changes has been the identification of new, more disinfection-resistant microorganisms such as Giardia and Cryptosporidium cysts and governmental regulations designed to protect the public health from the hazards of ingestion of these microorganisms. Additionally, the desire to prevent or minimize the formation of halogenated disinfection byproducts formed during chlorination has stimulated new interest in the use of ozone. Combinations of ozone with hydrogen peroxide and/or ultraviolet (UV) radiation can destroy many contaminants present in ground water.

Back to the Basics, Part 3

In this last section of a three-part series, the use of ozone, ionization, distillation and aeration is discussed in a simple fashion to help the beginner rationalize the importance for a full understanding of these technologies and the need, again, for a professional water treatment specialist.

This is the final article in a three-part series discussing water chemistry and technology basics.

Automated Chlorine Control Brings Precision to Water Reclamation Operation

Using reclaimed water for non-potable purposes as a means of conserving potable water supplies is the most prevalent method of water reuse in the United States today. One of the significant challenges for water reclamation facilities is to keep up with the demands for safe, compliant chlorine (Cl2) treatment. One utility that is effectively meeting this challenge is Southern California’s Otay Water District.

Advanced Technology Brings the Power to Chlorine Dioxide

Chlorine dioxide is an extremely effective and powerful biocide that has been used for many years as a bleaching agent and slimicide in the pulp and paper industry, as a disinfectant in municipal water treatment and in many other industrial water treatment operations. However, significant capital and operating costs have limited the use of chlorine dioxide to large-scale applications. New technology now makes it practical to use the biocide in a wider range of water treatment applications.

Effects of Recharge of Chlorinated State Water Project Waters to Groundwaters in Lancaster Area of California

As the population in Southern California increases, more and more demands are being put on the state’s groundwater resources, further exacerbating the overdraft problem. Many communities in Southern California are recharging their aquifers with imported surface waters to combat this problem. The major recharge normally is carried out during wet weather periods when surface water is plentiful. However, recharging these groundwater aquifers with imported surface water can create the potential for water quality degradation. The problem can start when surface water is disinfected with chlorine to prevent biofouling and remove pathogens.

Groundwaters in many parts of California are an important sole source of water supply. However, in some areas indiscriminate pumping has lowered aquifer levels by hundreds of feet. This has caused sediment compaction and ground subsidence.

Ultraviolet for Disinfection

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.

Chlorine Taste in the Customer’s Drinking Water?

Chlorine produces bacteria-free water and eliminates algae and slime. It also removes hydrogen sulfide from ground water (wells and springs) and eliminates iron bacteria (cenothrix), which are associated with objectionable odor and taste.

Despite these important facts, some people still object to chlorine in their drinking water. Comments such as “I don’t like the way chlorine makes my water taste” are common.

Metering Pump Technology

Since the introduction of the metering pump, chemical feed for disinfection has been a primary application. As we move into the 21st Century, it again is time to review how we introduce chemicals such as sodium hypochlorite into our water systems. While the goal remains the same, changes in pump technology have been created to provide more accurate and consistent results. This article will discuss current metering pump technologies, proper pump sizing, installation and future enhancements.
