Does Biological Activated Carbon Filtration Make Chlor(am)inated Drinking Water Safer

چکیده

Biological activated carbon (BAC) filtration is an effective technology for the removal of natural organic matter. However, one potential drawback BAC, especially old that effluents can contain soluble microbial products released from biofilm, which are recognized as more toxic nitrogenous DBPs (N-DBPs) precursors. So far, limited studies reported risk DBP formation potentials (FPs) increase caused by leakage BAC. This study compared differences FPs between two BAC filters operated 1 year and 8 years in a drinking water plant. The results showed total summed haloacetic acid trihalomethane decreased 34.31% chlorination, 55.01% halogen acetonitrile chloramination were removed new Chlorinated haloacetonitriles increased 2.33% after filtration. To sum up, most FPs, but regarding N-DBP should receive attention.

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...

Safer sips: removing arsenic from drinking water.

U.S. researchers are developing technologies that may someday protect millions of people worldwide whose drinking water is tainted with arsenic. Arsenic is released into water from soil and rock erosion, and is also a by-product of industrial processes including semiconductor manufacturing, petroleum refining, and mining and smelting operations.

Bacteria 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...

An innovative treatment concept for future drinking water production: fluidized ion exchange – ultrafiltration – nanofiltration – granular activated carbon filtration

A new treatment concept for drinking water production from surface water has been investigated on a pilot scale. The treatment concept consists of fluidized ion exchange (FIEX), ultrafiltration (UF), nanofiltration (NF), and granular activated carbon filtration (GAC). The FIEX process removed calcium and other divalent cations; the UF membrane removed particles and micro-organisms; and the NF m...
