Bushfire and water quality

Bushfires pose a great risk to drinking water quality in water tanks, water catchment facilities and water supply infrastructure. Generation of large amounts of smoke, ash and debris leads to contamination of water in water tanks and on roof catchment infrastructure like gutters. In extreme cases, it is possible that fire retardants or foams used to control the fire may also be deposited on roof ...

Advanced technology for water purification by heterogeneous photocatalysis

The TiO2 photocatalytic degradation of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) was examined using a prototype photoreactor fabricated by Nulite. The degradation of both pollutants proved very efficient as in 12 min it was possible to bring the concentration of 2,4-DCP from 10 to 0.5 p.p.m. and in a separate experiment the concentration of PCP from 100 to 0.5 p.p.b. The effect of ...

Inactivation of particle-associated Escherichia coli with chlorine dioxide

In this paper, the inactivation of both free Escherichia coli (FE) and particle-associated E. coli (PAE) with chlorine dioxide (ClO2) were investigated using granular activated carbon effluent water samples. The inactivation rate of FE was higher than that of PAE and the reactivation ratio of PAE was higher than that of FE, indicating the threat of particle-associated bacteria. Response ...

How can drinking water treatments influence chlorine dioxide consumption and by-product formation in final disinfection?

In this study water samples of different origins (subalpine lake, artificial lake and river) were treated by pre-oxidation, coagulation/flocculation, adsorption on granular activated carbon and disinfection. Different laboratory-scale tests were carried out to evaluate the treatment impact on ClO2 consumption in disinfection and on the formation of disinfection by-products (trihalomethanes, ...
