What’s Inside

ACTIVITIES & EVENTS

About WG1

Objectives

To assess the state of the art, maturity and energy requirement of innovative efficient technologies for wastewater treatment.

Energetic self-sufficiency

Options for minimising energy consumption and optimising energy production are investigated, aiming at converting WWTPs in net energy providers. This includes activities on energy efficient processes, such as low-temperature autotrophic nitrogen removal, anaerobic – aerobic hybrid MBRs, membrane aerated biofilm reactors, supercritical water oxidation, etc.; as well as on energy recovery alternatives, like sewage sludge (co-)incineration or anaerobic (co-)digestion, microalgae photobioreactors integrated with anaerobic (co)digestion and bioelectrochemical systems (microbial fuel cells, hydrogen, etc.).

Presentation and

Objectives

The main objective of TG3 is to review the micropollutants in wastewater treatment worldwide and to communicate this issue in europe.

In fact, across Europe, most people don´t know where our drinking water comes from, or how big the efforts are to allow us to perform the most normal daily action, namely to open the tap and to consume clean, clear and pure water. Still, it is the extremely high quality of our drinking water that ensures the healthy life we lead. In fact, to provide unpolluted water as a resource for drinking water supply, food production but also other aspects of daily life, is one of the major challenges for Europe in the closer future. Whereas well-assessed treatment strategies exist for classical issues such as removal of nutrients (phosphorus and nitrogen), detergents and even microorganisms, novel emergent organic compounds pose a threat to our water reserves. More than 100,000 different chemi¬cals are presently distributed on the European market, one third of them exceeding quantities of one ton per year. Thanks to the continuous improvement of analytical techniques, a large number of pharmaceuticals has been detected and identified frequently during the last years in effluents from wastewater treatment plant, surface waters or ground waters. Since the majority of all significant waters, lakes and streams are shared between several European countries, the EU has to find a common strategy for the treatment of wastewater, and a zero pollution regime for effluents. Furthermore it will be necessary to expand the scope of water protection to all waters, surface waters and groundwater; to achieve satisfactory status for all waters by a set deadline; and to delegate water management to regional authorities based on river basins.

As regards the second task which regards the organization of an e-learning unit on micropollutant removal, a progress was recently made. A first list of members interested in giving the online lessons on the topic of micropollutant in WWTPs has been created, which also proposed some specific topics to be addressed. The outline of the learning course is as follows:

TG4 — Efficient sludge technologies Activity summary

The main activities have been addressed to identify the novel and emerging technologies to valorise sewage sludge. A part from the well-established technologies, many other initiatives have been promoted Worldwide to recover resources (materials and energy) from sludge. In this sense the research that have been done tried to identify these technologies and initiatives, to assess the state of development, considering the pilot and demonstration plants that have been implemented and the results obtained in the considered plants. A part from that, a special attention has been paid to the biodrying technologies since members of TG4 are specialists on this field. Furthermore, particular cooperation has merged among the TG members, with some Post-Doc short and long stays mainly between University of Vic and University of Verona.

Objectives

The main objective of TG4 is to review the advanced sludge treatment technologies worldwide and to develop a common strategy in Europe.

Sludge has been considered and treated during many years as a waste and the strategies proposed had as objective a safe disposal of the sludge. However during the last years it has been demonstrated that sewage sludge can be considered as a source for both energy and raw materials.

In this task group the most advanced technologies and processes aiming focused on the resource recovery from sewage sludge will be listed and analysed to determine the most promising technologies. Among these technologies we can find some well-consolidated biological processes such us anaerobic digestion and composting while some thermal treatments such as Drying and Incineration can be also found and implemented at industrial level in Europe.

However, the TG4 will pay special attention to the novel technologies such as Pyrolysis and Gasification and to the emerging technologies that are currently being developed being the most important the Supercritical Water Gasification and Biodrying.

The benefits, advantages, weaknesses and disadvantages of the current, novel and emerging technologies will be studied so as result some recommendations could be done in order to develop an appropriate future strategy for the sustainable processing of the sewage sludge.

Presentation and

Objectives

Wastewater treatment plants are typically the largest energy consumers of municipalities. There are many methods and processes to treat wastewater, where the secondary aerobic treatment is the largest energy consumer (30 to 60% of total plant usage). The current demand for switching from carbon removal to both carbon removal and nitrification/de-nitrification lead to an increase of the total plant energy consumption by 40 to 50 percent (Metcalf and Eddy, 2003).

In recent years, there has been growing interests in anaerobic biological treatment for low-strength wastewaters because of its low energy consumption, minimized sludge production and energy recovery through biogas production. Although research suggests that anaerobic treatment of low-strength domestic wastewater is possible in temperate climates, to date, full-scale applications have only been pioneered in hot regions (i.e. Latin America, India).

The overall objective of TG5 is to explore the different constrains and problem that limit the diffusion of anaerobic treatment for domestic wastewater and the application of full-scale based on the innovative anaerobic technologies that can increase the process stability. In addition, efforts will be given to explore the challenges for this application including technical and operational aspects as well as the potential for more benefical products (i.e., organic acids, biopolymers).

TG6 — Aerobic granular reactors Activity summary

The main activities have been addressed to analyze the granular sludge bioreactors from fundamentals to application covering microbiological, chemical and engineering aspects in order to evaluate the mature level of this technique and at the same time to identify the unsolved issues that have prevented the widespread application at full scale wastewater treatment plants. Furthermore, particular attention has been paid for sharing experiences and skills of the members of the task group.

Presentation and Objectives

The aerobic sludge granulation is attracting more and more interest from researchers worldwide. in fact after the first paper published in 1997, the number of papers per year has continuously increased during the last decade reaching 120 in 2014 (source: scopus). the number of papers published from the beginning of the current year also indicates that probably during this year it will be exceeded this figure.

Although the high interest and the significant advantages of the aerobic granular bioreactors over the conventional technologies (consisting in a both low energy and area requirement) only a few full scale applications have been reported so far after almost two decades from its first development.

The overall objective of this task is to create a group of experts in the field of aerobic granular bioreactors for exchanging experience in order to shed light on the reasons that have prevented or slowed the full scale application of this innovative treatment technique
