Controoling chlorine costs

The most widespread disinfectant used in the treatment of drinking water is chlorine, which can be applied in a variety of ways. History has taught us that, in bacteriological terms, chlorinating water is a proven way of disinfecting drinking water. After all, more than 75 years have passed since chlorine was used to disinfect drinking water for the first time. Many years of experience have shown ...

Chlorine Theory & Measurement

Chlorine, dissolved in liquid is one of the most effective and economical semi-killers for the treatment of water to make it potable or safe to drink. Chlorine's powerful disinfectant qualities come from its ability to bond with and destroy the outer surfaces of bacteria and viruses. Drinking water chlorination is one of the most widely used methods to safeguard chinking water supplies. In ...

Effect of wastewater chlorination on endocrine disruptor removal

Endocrine disrupting chemicals (EDCs) are compounds of mainly anthropogenic origin that interfere with the endocrine system of animals and humans thus causing a series of disorders. Wastewater treatment plants are one of the major routes for transporting such chemicals to the water courses. In the context of this study, several chlorination batch tests were performed in order to assess the ...

Direct Hydrogen Addition for the In-situ Biodegradation of Chlorinated Solvents

As a result of their widespread use as solvents, degreasers, and dry cleaning agents, chlorinated aliphatic hydrocarbons (PCE, TCE, DCE, etc.) represent one of the most common and most persistent groups of contaminants found in groundwater. Characteristically, these compounds exist in the form of DNAPLs in the subsurface making efforts at remediation particularly difficult. In-situ bioremediation ...

How to keep drinking water safe from `little animals`

Disease causing agents can be broken up into three groups, Bacteria, Viruses and Protozoa. Cryptosporidium belongs to the third group, Protozoa. The word protozoa comes from the Greek word for ‘little animal’.One aspect of Cryptosporidium which makes it problematic from a water treatment perspective is that at one stage in its life cycle it produces small spore like bodies known as cysts. These ...
