Identification and assessment of water quality risks associated with sludge supernatant recycling in the presence of cyanobacteria
This study focussed on the fate of cyanobacteria cells and associated metabolites during the sludge management processes that follow the conventional drinking water treatment train. The topic is of importance, as the release of metabolites during sludge treatment may pose a risk to water quality if supernatant is recycled to the head of the plant. The study of the kinetics of cell damage and ...

Removal of NOM-constituents as characterized by LC-OCD and F-EEM during drinking water treatment
Natural organic matter (NOM) is of concern in drinking water because it causes adverse aesthetic qualities such as taste, odour, and colour; impedes the performance of treatment processes; and decreases the effectiveness of oxidants and disinfectants while contributing to undesirable disinfection by-products. The effective removal of NOM during drinking water treatment requires a good ...

Tracking disinfection by-products and arsenic removal during various drinking water treatment trains
In the central Banat region (Northern Serbia), groundwater is used as a drinking water source. Raw water originates from a 40–80 m and 100–150 m deep layer. It contains a high amount of natural organic matter (DOC = 9.17±0.87 mg C/L) with a trihalomethanes formation potential of 448±88.2 μg/L and a haloacetic acid formation potential of 174±68.9 μg/L. A high amount of arsenic (86.0±3.4 μg/L) is ...

Dissolved organic nitrogen (DON) in a full-scale drinking water treatment plant
Dissolved organic nitrogen (DON) is currently considered as one of the most important parameters in drinking water treatment due to its potential to form toxic nitrogenous disinfection by-products (N-DBPs). A comprehensive investigation was made in this study on the variation of DON in a full-scale drinking water treatment plant with a treatment train of coagulation/sedimentation, biofiltration ...
