Evaluations of conventional, ozone and UV/H2O2 for removal of emerging contaminants and THM-FPs
Although potential risk of pharmaceuticals and personal care products (PPCPs) and endocrine disrupting compounds (EDCs) and trihalomethanes to humans is small or unconfirmed, it is advisable to remove these wastewater-related contaminants to increase public confidence and acceptance as a precautionary principle and consequently their elimination or reduction during drinking water treatment is warranted. Experiments were conducted using the dual train pilot-scale conventional treatment plant with ozone and ultraviolet/hydrogen peroxide (UV/H2O2) with three different raw water sources. Reductions of trihalomethanes-formation potentials (THM-FPs) were 8–52%. Ozone was found to decrease THM-FPs while UV/H2O2 was found to increase THM-FPs in most of the experiments under experimental conditions. Conventional treatment poorly removed the selected PPCPs and EDCs while ozone + conventional treatment provided excellent removal. Conventional + UV/H2O2 treatment also demonstrated effective removal. However, removal of PPCPs and EDCs by conventional + UV/H2O2 treatment provided lower efficacy for Sites B and C, likely due to the presence of scavengers such as organics, bicarbonates, carbonates and particles.
期刊介绍：
The Water Quality Research Journal publishes peer-reviewed, scholarly articles on the following general subject areas:
Impact of current and emerging contaminants on aquatic ecosystems
Aquatic ecology (ecohydrology and ecohydraulics, invasive species, biodiversity, and aquatic species at risk)
Conservation and protection of aquatic environments
Responsible resource development and water quality (mining, forestry, hydropower, oil and gas)
Drinking water, wastewater and stormwater treatment technologies and strategies
Impacts and solutions of diffuse pollution (urban and agricultural run-off) on water quality
Industrial water quality
Used water: Reuse and resource recovery
Groundwater quality (management, remediation, fracking, legacy contaminants)
Assessment of surface and subsurface water quality
Regulations, economics, strategies and policies related to water quality
Social science issues in relation to water quality
Water quality in remote areas
Water quality in cold climates
The Water Quality Research Journal is a quarterly publication. It is a forum for original research dealing with the aquatic environment, and should report new and significant findings that advance the understanding of the field. Critical review articles are especially encouraged.
