Bacterial community and function of biological activated carbon filter in drinking water treatment.
OBJECTIVE It aims to investigate the changes in composition and structure of bacterial communities developing on biological activated carbon (BAC) particles, and the bacterial functions. METHOD A pilot plant had been in service for 180 days, aiming to develop bacterial communities on activated carbon naturally. After 180 days of operation, the bacterial communities were determined by denaturi...
متن کاملBehavioral toxicity of trihalomethane contaminants of drinking water in mice.
The behavioral toxicity of trichloromethane (TCM), dichlorobromomethane (DCBM), dibromochloromethane (DBCM) and tribromomethane (TBM) was evaluated following oral administration in mice. A variety of dosage regimens and behavioral measures were used. Studies included acute dose effect, 14-and 90-day treatments at 300 and 3000 times the estimated average human daily intake of contaminated drinki...
متن کاملTrihalomethane hydrolysis in drinking water at elevated temperatures.
Hydrolysis could contribute to the loss of trihalomethanes (THMs) in the drinking water at elevated temperatures. This study was aimed at investigating THM hydrolysis pertaining to the storage of hot boiled water in enclosed containers. The water pH value was in the range of 6.1-8.2 and the water temperature was varied from 65 to 95 °C. The effects of halide ions, natural organic matter, and dr...
متن کاملBacteria associated with granular activated carbon particles in drinking water.
A sampling protocol was developed to examine particles released from granular activated carbon filter beds. A gauze filter/Swinnex procedure was used to collect carbon fines from 201 granular activated carbon-treated drinking water samples over 12 months. Application of a homogenization procedure (developed previously) indicated that 41.4% of the water samples had heterotrophic plate count bact...
متن کاملCadmium contamination of drinking water and its treatment using biological chelators
Background: Cadmium (Cd) is an extremely toxic metal and environmental exposure to Cd has been particularly problematic in the world. Oral exposure to Cd may result in adverse effects on a number of tissues, the immune system, and the cardiovascular system. Compounds containing Cd are also carcinogenic. The presence of Cd in drinking water resources in the southeastern region of Rafsanjan plain...
