Single artificial wetland successfully treats different types of wastewater

The world's first full-scale artificial wetland designed to treat both sewage effluent and mine wastewater has been found to continuously remove high levels of pollutants, a recent study concludes. Treating both types of wastewater at the same time proved to be highly beneficial because they contain pollutants which are more easily removed when mixed together.

New incineration-waste clean-up method brings resource and carbon benefits

Ash from waste incineration can be made safer simply by mixing it with rice husks, water and other forms of waste ash at temperatures under 100 °C, according to new research. Once dried, the end product not only locks away toxic metals lead and zinc, but also stores carbon. Furthermore, it can be used in the polymer industry to lower costs, improve polymer properties and reduce the use of natural resources.

Chemical composition of fracking wastewater

Wastewater produced by hydraulic fracturing, or ‘fracking’, has been chemically analysed in the most comprehensive study of its kind to date. The researchers found that produced water from three US fracking sites contained a diverse array of chemicals including toxic metals such as mercury and the carcinogens toluene and ethylbenzene. However, a group of harmful chemicals, ‘polyaromatic hydrocarbons’ commonly found in mining and coal extraction wastewater, were absent.

Active pharmaceutical ingredients in wastewater: who are the major contributors?

Active pharmaceutical ingredients (APIs) — responsible for the biological activity of drugs — have been widely found in the environment, yet the precise sources and relative importance of emissions via wastewater are not quite clear. This study assessed emissions from three health institutions in Germany — a hospital, a psychiatric hospital, and a nursing home — and found their contribution was low compared to that from households. However, more research is needed to understand the environmental effects of neurological drugs, emissions of which were in some cases relatively high.

Wastewater treatment plant discharges can promote the development of antibiotic resistance in streams

Widespread use of antibiotics has led to pollution of waterways, potentially creating resistance among freshwater bacterial communities. A new study looked for antibiotic resistance genes in a river basin in Spain, revealing that wastewater discharges can promote the spread of antibiotic resistance in streams and small rivers.

Harmful polycyclic aromatic hydrocarbons removed from soil using wastewater sludge and polyacrylamide

Wastewater sludge is widely used to remove toxic polycyclic aromatic hydrocarbons (PAHs) from soil, and yet the mechanisms underlying this process remain unclear. A new study reveals the extent of PAH removal following different treatments, and could provide a useful resource for those looking to diminish the effects that these pollutants have both on people and on the environment.

Biodegradation of PPCPs in wastewater treatment plants — a Danish case study

The non-restricted production and use of pharmaceuticals and personal care products (PPCPs) has led to their presence in effluents from treatment plants, which can pose a threat to aquatic organisms downstream. This study analysed the breakdown of six common chemicals in four Danish treatment plants. The findings shed new light on the factors affecting removal of PPCPs from waste, showing that the composition of waste is more important than the design of the treatment plant.

Asbestos products and waste: new classification system developed

Researchers have presented a comprehensive new classification manual of asbestos-containing products (ACP), materials (ACM) and waste (ACW) in a recent study. They also mapped suitable landfill sites for the proper disposal of ACW in Italy and developed guidance on assigning ACW to correct European Waste Catalogue (EWC) codes. The research will help operators engaged in asbestos waste disposal across Europe and should contribute to aims for the total removal of asbestos from the EU.

Separate waste-water treatment of urine could have lower environmental impact than centralised, combined waste-water treatment

Municipal wastewater is a major source of pharmaceuticals in the aquatic environment. Results from a recent study suggest that collecting and treating urine separately from other forms of sewage could be a cost-effective way to reduce the harmful effects of pharmaceuticals on the environment, while also providing a source of nutrients for fertilising agricultural crops.

Waste-water analysis highlights exposure to endocrine-disrupting phthalate plasticisers

Researchers in Spain have analysed waste water to calculate levels of exposure to phthalates in individuals. The calculations showed that levels of four types of phthalate exceeded safe daily limits in some of the sites studied, with levels of exposure in children being of particular concern. Using the results of waste-water analysis in this way can identify areas where action may need to be taken to lower exposure.

Radiation processing may be faster, cleaner and more efficient at removing pollutants from drinking and waste water than conventional techniques

The presence of organic pollutants in waste water and drinking water can have alarming environmental and public health implications. Current water treatment methods have limitations: they can only remove certain contaminants, to certain extents, and also produce harmful by-products. New and improved methods are required. A recent review paper presents radiation processing as a promising approach, providing strong evidence of its efficacy, efficiency, safety, and feasibility. Focusing particularly on the use of electron-beam processing for the removal of organic pollutants from waste water and drinking water, the researchers present a compelling picture, relevant to stakeholders involved in water treatment and management.

Clarity needed on environmental impact of plastic waste for evidence-based policy

Plastic waste in the environment presents cause for concern, but scientific understanding of its exact impacts is still in its infancy. A team of Dutch scientists has presented recommendations on how to develop a new assessment method which provides clear, specific evidence on the risks of plastic waste. Once developed, this method could inform scientifically sound policies for managing plastic waste.

Waste legislation will affect emissions from waste incineration

Recently adopted EU waste legislation and its implementation at national level could have a significant effect on some countries’ emission loads for municipal solid waste incinerators, according to a recent study. The study suggests that the effects of increasing incineration over the next decade would be most profound for countries where incineration is currently only used on a small scale.

Waste incinerator impacts monitored via milk and vegetable quality

Emissions from well-regulated household waste incinerators do not reduce the quality of vegetables and milk produced nearby, a Dutch study suggests. Researchers found that levels of certain contaminants were similar whether vegetables and milk came from the area surrounding three incinerators, or from elsewhere in the Netherlands. They say biomonitoring programmes could offer a way to increase the understanding of the real impacts of waste incineration and to improve communication between waste management companies and local communities.

New energy-positive waste-water treatment process uses just 15% of the energy required for current alternative

Conventional municipal waste-water treatment processes are based on aeration, which is energy intensive. Now, researchers have developed an alternative waste-water treatment process. In addition to avoiding the use of aeration in favour of filtration/biofiltration and encapsulated denitrification (the application of capsules containing nitrifiers, which convert ammonium into nitrate), the process also uses waste biosolids to generate electrical energy. The process has been tested in a pilot facility and found to require just 15% of the energy required for conventional approaches. Moreover, the process is energy positive, as the biosolids are able to generate more than enough energy to power the treatment plant. If this technology could be scaled up to the municipal level, it could significantly reduce the energy use and environmental impacts of waste-water treatment.
