Drinking Water Chlorination Applications

Chlorine dioxide treatment for potable water

Chlorine dioxide is an effective tool for the treatment of potable water. It is a powerful disinfectant that nicely balances purification performance against disinfection by product formation. It is one of four EPA approved disinfectants for drinking water with CT values second only to ozone in biocidal efficacy but without the ozonation by-products or high capital expense.

Chlorine Dioxide Water Treatment for the Municipal Drinking Water Treatment

Chlorine dioxide is a well-known disinfectant for drinking water with many advantages over chlorination. Today there are estimated to be over 900 public water systems using chlorine dioxide for water disinfection world-wide. Also in Australia it is approved for a wide range of uses. However, the acceptance of chlorine dioxide in Australia as a disinfecting agent for drinking water has been hampered by the crude methods available for generating chlorine dioxide – methods that require relatively complex equipment and/or produce impure chlorine dioxide with many undesirable impurities.

Pig and Poultry Drinking Water Chlorine Dioxide Treatment

Successful pig and poultry farming demands that measures are taken to control the introduction and spread of infectious agents. Chlorine Dioxide has been used very successfully in farming and slaughterhouses as a processing aid that is added to maintain water of good microbial quality. CleanOxide Chlorine Dioxide is used for sanitising hard surfaces and processing equipment to assist in the prevention of the propagation and transmission of disease.

Ultraviolet disinfection systems for the drinking water inspectorate

With atg UV systems treating in excess of 2500 m3/hr daily, Ultraviolet disinfection is no longer an ‘emerging` technology. A number of Water Treatment Works across the world are now investing heavily in Ultraviolet technology as the threat of chlorine resistant parasites, such as Cryptosporidium and Giardia, continue to pose a serious risk to water companies and their customers. To this end, in the UK, the DWI have issued their guidelines for UV operation and system selection to the UK water industry. A key feature of their guidance is UV system validation. Validation refers to a series of 3rd party testing to ensure the performance of an Ultraviolet system design under a range of operating environments.

Early warning systems for drinking water

Drinking water supply and distribution systems around the world (a critical and interdependent component of a nation’s infrastructure) are vulnerable to both intentional and accidental contamination. Unusual water quality may serve as a warning of potential contamination. The available physico-chemical sensors utilize general water quality parameters, such as free chlorine, oxidation reduction potential (ORP), total organic carbon (TOC), turbidity, pH, dissolved oxygen, chloride, ammonia, nitrate to detect the contamination. Generally, one or more of these water quality parameters will change due to the injection of a contaminant. However, no single chemical sensor responds to all possible contaminants nor can they give any indication of the potential toxicity of complex mixtures.

Municipal Wastewater treatment for drinking water

As one of the world`s most precious natural resources, the reuse of water is becoming increasingly important. MIOX is both the most cost-effective solution and the preferred technology for disinfection and oxidation of wastewater for reuse or reintroduction into the environment. MIOX`s hypochlorite generators offer a safer, technologically superior solution to wastewater treatment, virtually eliminating many of the negative problems associated with traditional chlorine disinfection. Safer, economical and significantly more effective, MIOX is revolutionizing the process of making water safe again.

Determination of chlorate, perchlorate, and chlorite ions in drinking water including bottled water

Introduction

Chlorination remains the most widespread way of disinfecting water in the world. Its flaws are: high toxicity of chlorine and other chlorinating reagents, also formation of various chlorine-containing compounds, including chlorite-, chlorate, and perchlorate anions. Maximum permitted levels (MPL) of these components are established in WHO Guidelines for drinking water and other regional and national regulations.

Chlorine dioxide tablets

The importance of drinking water quality for the production and performance of poultry has become one of the most important management tools. Without an adequate supply of good quality water, bird performance will be impacted. The key is not just the adequate supply of water, but good quality water. One prime factor that determines the wholesomeness of water is its microbial quality. Therefore, it should be of primary concern for production personnel and poultry producers to know the microbial quality of water supplies provided to their birds and confirm if it is within the acceptable range. GlobalEx tablets is the most effective tool for water sanitation management for livestock and poultry. GlobalEx keeps the bacteria level down in the water lines, and prevents biofilm (slime) from developing thus keeping the animals and birds healthier by keeping down the pathogen level that could potentially travel from one to another.

Drinking water solutions for the TOC removal efficiency

Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.

Industrial water TOC and Color removal from water

All surface waters contain varying amounts of naturally occurring organic acids. The most commonly encountered being tannic and humic. These substances have varying molecular weights and varying amounts of carboxylic functionality. There has been much interest in the removal of these substances from drinking water supplies due to their tendency to form THM`s when chlorinated. They can be removed effectively by use of anion exchange resins operated in the chloride cycle. Because the organics can be removed by regeneration with brine, this technology is far most economical.
