Alternative Electrode Materials and Ceramic Filter Minimize Disinfection Byproducts in Point-of-Use Electrochemical Water Treatment

Disinfection byproducts in swimming pool water in Sanandj, Iran

The present study aimed to determine the concentrations of several disinfection byproducts (DBPs), including trihalomethanes (THMs), haloacetic acids (HAAs), and haloacetonitriles (HANs), in the public and private swimming pools in Sanandaj, Iran (n=16). Correlations between DBP levels with water quality parameters (free chlorine, pH, total organic carbon, temperature, number of swimme...

Sustainable colloidal-silver-impregnated ceramic filter for point-of-use water treatment.

Cylindrical colloidal-silver-impregnated ceramic filters for household (point-of-use) water treatment were manufactured and tested for performance in the laboratory with respect to flow rate and bacteria transport. Filters were manufactured by combining clay-rich soil with water, grog (previously fired clay), and flour, pressing them into cylinders, and firing them at 900 degrees C for 8 h. The...

MEDICAL USE OF CERAMIC MATERIALS

Drowning in disinfection byproducts? Assessing swimming pool water.

Disinfection is mandatory for swimming pools: public pools are usually disinfected by gaseous chlorine or sodium hypochlorite and cartridge filters; home pools typically use stabilized chlorine. These methods produce a variety of disinfection byproducts (DBPs), such as trihalomethanes (THMs), which are regulated carcinogenic DBPs in drinking water that have been detected in the blood and breath...

Drinking water disinfection byproducts: review and approach to toxicity evaluation.

There is widespread potential for human exposure to disinfection byproducts (DBPs) in drinking water because everyone drinks, bathes, cooks, and cleans with water. The need for clean and safe water led the U.S. Congress to pass the Safe Drinking Water Act more than 20 years ago in 1974. In 1976, chloroform, a trihalomethane (THM) and a principal DBP, was shown to be carcinogenic in rodents. Thi...
