Characterization of soluble microbial products as precursors of disinfection byproducts in drinking water supply.

Biodegradation and biotransformation of wastewater organics as precursors of disinfection byproducts in water.

Laboratory experiments were carried out to investigate wastewater organics as the precursors of disinfection byproducts (DBPs) in drinking water supply. The focus was on the change in wastewater DBP precursors during biological degradation under simulated natural conditions. The wastewater and its treated secondary effluent were characterized for DBP formation potential (DBPFP) and DBP speciati...

Trihalomethane formation potential in drinking water from Minab Steghlal dam to water distribution network in Bandar Abbas, Iran

Introduction: Organic matters enter to drinking water from a variety of sources, but one of the major sources of these compounds in aqueous solution can be decomposed plant and microbial residues. Chlorination is the most common method for water disinfection, the free chlorine in the water reacts with natural organic compounds and form disinfection byproducts. One of the dangerous byproducts is...

Models for predicting disinfection byproduct (DBP) formation in drinking waters: a chronological review.

Disinfection for the supply of safe drinking water forms a variety of known and unknown byproducts through reactions between the disinfectants and natural organic matter. Chronic exposure to disinfection byproducts through the ingestion of drinking water, inhalation and dermal contact during regular indoor activities (e.g., showering, bathing, cooking) may pose cancer and non-cancer risks to hu...

The contribution of the antibiotic chloramphenicol and its analogues as precursors 1 of dichloroacetamide and other disinfection byproducts in drinking water 2

Impacts of drinking water pretreatments on the formation of nitrogenous disinfection by-products.

The formation of disinfection by-products (DBPs), including both nitrogenous DBPs (N-DBPs) and carbonaceous DBPs (C-DBPs), was investigated by analyzing chlorinated water samples following the application of three pretreatment processes: (i) powdered activated carbon (PAC) adsorption; (ii) KMnO(4) oxidation and (iii) biological contact oxidation (BCO), coupled with conventional water treatment ...
