drinking water chlorination Applications

Problem: Drinking water plants that use chlorine for disinfection must ensure organic matter is removed before chlorination to limit the formation of harmful disinfection by-products (DBPs), most commonly Trihalomethanes (THMs) and Haloacetic acids (HAA5).

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...

The purpose of de-chlorination is the removal of free chlorine and combined chlorine compounds from potable water, as supplied by municipal water supplies. Chlorine will oxidize the surface of thin film composite polyamide membranes, causing the membrane to lose its ability to repel or reject salts. As a result, the membranes used in Reverse Osmosis (RO) or Electro-deionisation (EDI) systems will exhibit shorter lifetimes when exposed to chlorine in the water they are treating and membrane manufacturers will...

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.

Experience fresh and safe water using Ultima PF controllers. Water is essential for life. Our bodies are made up of 80% water; hence water is one of the main components we need to function in a healthy manner. Water disinfection can be attained by means of chemical disinfectants which should not only kill microorganisms, but also must leave a residual effect in order to keep them active in the water after disinfection. Aquarius Ultima PF controller (UPF) provides powerful and consistent control on the residual of...

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...

The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.

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.
