The economic viability of wastewater reuse projects could be better determined using methodology from a new study. The authors developed a five-step cost-benefit analysis framework to assess a planned wastewater reuse project within the catchment of the Yarqon River, in Tel Aviv Metropolitan Area, Israel. It was found that the scheme could have a net present value of $4.83 (€4.34) million per year. The authors highlight the relevance of identifying external as well as internal economic, social and environmental costs of such projects.

A comprehensive analysis of pharmaceuticals in Spanish wastewater has indicated that they are widespread pollutants. The majority of pharmaceuticals present in incoming wastewater were still present in both treated water and in the river waters receiving the treated water.

A recent study compared the decentralised treatment of pharmaceutical contaminants in wastewater at hospitals with centralised treatment at conventional and upgraded wastewater plants. The results suggest that additional (post) treatments may not always provide significant benefits.

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.

Farmers could help to maintain populations of bees and other pollinators by sowing inexpensive seed mixes on their land, a new study suggests. Researchers surveyed pollinators visiting study plots in Berkshire, UK, and explored how sowing different seed mixes and using different management techniques affected the flowers produced and the pollinators visiting them.

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.

Wastewater emptied from commercial fishing boats is an overlooked source of marine pollution, a new US study shows. The researchers suggest that this type of pollution should be given further consideration when assessing the overall environmental impact of fishing, as it may pose a risk to human health and marine life.

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.

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.

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.

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.

A new study has compared treatments to reduce odour from wastewater treatment plants, and has suggested that biotrickling filtration and activated sludge diffusion are the two most promising technologies. These appear to perform best on a combination of environmental, economic and social indicators.

Agencies and organizations deploy various strategies in response to environmental challenges, including the formulation of policy, programs, and regulations. Citizen-based environmental stewardship is increasingly seen as an innovative and important approach to improving and conserving landscape health. A new research focus on the stewardship of urban natural resources is being launched by the U.S. Forest Service in the Pacific Northwest region. Early scoping efforts are addressing various scales of human systems ranging from individuals to organizations to the entire positive "footprint" of stewardship on the land. This report addresses a fundamental need—to understand and describe civic environmental stewardship in urban settings. Stewardship has been described and defined in diverse ways within a variety of contexts, including the philosophical literature of environmentalism, agency program descriptions, and outreach by sponsoring organizations. Constructing a framework to convey the layered meanings of stewardship will help to focus and guide future research. A cognitive mapping technique was used to elicit responses to the question "What is environmental stewardship?" Semistructured interviews were conducted with representatives of nine Seattle environmental organizations, a group of practitioners who collectively represent over 100 years of experience in the field. Program planners and managers have particularly direct experiences of stewardship. Cognitive mapping enables participants to explore, then display, their particular knowledge and perceptions about an idea or activity. Analysis generated thematic, structural representations of shared concepts. Results show that the practitioners have multilayered perceptions of stewardship, from environmental improvement to community building, and from actions to outcomes. The resulting conceptual framework demonstrates the full extent of stewardship activity and meaning, which can aid stewardship sponsors to improve stewardship programs, leading to better experiences for participants and higher quality outcomes for projects and environments.

The concept of ecosystem services has emerged as a way of framing and describing the comprehensive set of benefits that people receive from nature. These include commonly recognized goods like timber and fresh water, as well as processes like climate regulation and water purification, and aesthetic, spiritual, and cultural benefits. The USDA Forest Service has been exploring use of the framework of ecosystem services as a way to describe goods and services provided by federal lands and attract and build partnerships with stakeholders and nongovernmental organizations. More recently, the agency has sought place-based example applications of the ecosystem service framework to explore its possible use as a tool to guide forest management, and better illustrate the concept for policymakers, managers, and potential national forest partners.

Certain exemplary embodiments can provide a system, machine, device, manufacture, circuit, composition, and/or user interface adapted for and/or resulting from, and/or a method and/or machine-readable medium comprising machine-implementable instructions for, activities that can comprise and/or relate to, in a treatment zone, reacting an oxygen-comprising gas, one or more selected ferric/ferrous chelates, one or more selected nitrates and/or nitrites, and/or anaerobic wastewater.

The present invention describes a method of optimizing CO2 concentration to increase the specific growth rate of Anammox bacteria and methanogens in wastewater and sludge treatment, as well as novel systems and methods of treating wastewater and sludge. The specific growth rate or doubling time of the Anammox bacteria and methanogens were determined to be sensitive to dissolved CO2 concentration. Optimizing dissolved CO2 concentration increases the specific growth rate of the Anammox bacteria, which may be used as an alternative biological nitrogen removal process for the treatment of domestic wastewater. In the method and system of treating sludge, the CO2 stripper returns biogas with low CO2 concentration to the headspace of an anaerobic digester in order to lower the headspace CO2 concentration and therefore, the soluble CO2 concentration. The lower soluble CO2 concentration increases the specific growth rate of the methanogens for a more efficient anaerobic digestion process.

The invention relates to a method for treating wastewater containing nitroaromatics and nitrohydroxyaromatics, as for example arises in the production of nitroaromatics or in the production of nitrohydroxyaromatics, by a two-stage method consisting of pre-reduction and wet oxidation.

A tank or bed has a plurality of sidewalls that create a bed cavity and a Fresnel panel frame that includes at least one Fresnel panel. The Fresnel panel frame may be adjacent to the bed cavity and may cover at least a portion of the bed cavity. An amount of sludge may be contained within the bed cavity. When placed in sunlight, the heat enhanced by the Fresnel panels may heat the sludge sufficiently for the sludge to be used as fertilizer.

A wastewater geothermal heat system is supplied with processed wastewater through a drip field in proximity to a thermal array part of a geothermal heat pump system. The wastewater treatment system portion provides a periodic source of treated wastewater. Several sensors and a control system regulate a pump that discharges wastewater from the treatment system and enters a drip field where it is released into the surrounding soil. The dampened soil provides an efficient vehicle to transfer heat into or out of a thermal array which is positioned adjacent to the drip field such that it is in contact with the soil that is dampened by the discharged wastewater.

Provided is a method for reducing COD of wastewater with improved utilization efficiency of ozone. The method achieves an objective by adding agents for removing hydroxyl radical scavengers produced by base-catalyzed ozone advanced oxidation to wastewater. The addition of calcium ion, barium ion, etc. to a base-catalyzed ozonation system makes the hydroxyl radical scavengers form precipitates, separated from water and lose the capability of scavenging hydroxyl radicals, thereby enhancing ozone utilization efficiency. Furthermore, calcium ion, barium ion, etc. form precipitates with partial organic acids yielded in the wastewater ozonation and are separated from water, hence diminishing ozone consumption and indirectly improving the ozone utilization efficiency in the wastewater treatment. The present invention can not only significantly enhance the reaction rate and utilization efficiency of ozone, saving reaction time and costs, but also enable complete mineralization of the organic compounds, significantly reducing COD and total phosphorus of wastewater.
