European Water Disinfection Practices Parallel U.S
Chlorination Widely Practiced. As in the United States, a large number of treatment plants use chlorine for disinfection in the treatment process and in the distribution system, although ozone is more frequently used for taste and odor control.
In 1905 the London Metropolitan Water Board started applying drinking water disinfection after researching the disinfection mechanism of chlorine in water purification. This organisation was of the opinion that chlorine disinfection was a suitable alternative for long-term storage of raw water.
WHO | Alternative drinking-water disinfectants:
Alternative drinking-water disinfectants: Bromine, iodine and silver.
During a one-year study at Jefferson Parish, Louisiana the chemical, microbiological, and mutagenic effects of using the major drinking water disinfectants (chlorine, chlorine dioxide, chloramine, ozone) were evaluated. ests were performed on samples collected from various treatment streams. hese tests evaluated eighteen of the halogenated disinfection by-products, surrogates such as TOC and TOX, microorganisms such as MS2, phage, coliforms, and heterotrophs, assimilable organic carbon, and
Bromine, iodine and silver
Part I – Bromine as a drinking-water disinfectant 5 Acknowledgements The World Health Organization (WHO) wishes to express its appreciation to all whose efforts made possible the development and publication of Part I - Bromine as a drinking-water disinfectant. The lead authors of Part I were:
Disinfection byproducts (DBPs) form when using chlorine. For this reason, water systems may choose to use alternate disinfectants. These alternate disinfectants for drinking water treatment include: Chloramines Chlorine dioxide (ClO2) Ozone (O3) Ultraviolet Radiation (UV)
Comparison of disinfection byproduct formation
Drinking water disinfection is vital for preventing the spread of diseases caused by waterborne pathogens, however, chemical disinfectants can also form byproducts with potential health concerns. Chlorine reacts with natural organic matter (NOM) to produce halogenated disinfection byproducts (DBPs).
and requires less treatment. In the case of surface water, pre-treatment such as coagulation, sedimentation and filtration is generally used to prepare the water before its final disinfection. Hence, apt protective measures and management of raw water reservoirs are capable of minimising need for chemical disinfection of the drinking water.

Chlorine Substitutes In Water May Have Risks : NPR
Water systems across the country are changing the way they treat drinking water because the traditional disinfectant, chlorine, can leave behind toxic chemicals. But alternatives to chlorine have
New edition covers the latest practices, regulations, and alternative disinfectants. Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment.

- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- What is the molecular formula of poly-aluminum chloride?
- One of the major pre-polymerized coagulants, poly-aluminum chloride (PACl) is used broadly for water and wastewater treatment. PACl contains different amounts of hydroxyl, and the molecular formula of PACl is [Al m (OH) n (H 2 O) x]·Cl 3m−n (n ≤ 3 m).
