Energy Saving in Sewerage Sector in Discussion

July 2014

Last 3rd of July took place the technical workshop "Energy Saving in Sewerage Sector", where representatives of public administration, technological companies and the university discussed the latest efficiency energy strategies applied in wastewater.

Organized by Adasa in Barcelona, and with the support of the Catalan Water Agency and other institutions such as the Catalan Institute for Water Research (Instituto Catalán de Investigación del Agua), Catalonia Water (Aguas de Cataluña) and the University of Extremadura (Universidad de Extremadura), this seminar become an interesting meeting point and technical forum.

The Catalan Water Agency explained the successful results of the implantation of OptimEDAR in Carme WWTP (Catalonia, Spain), where a reduction of 15% of the power consumption was achieved, and a strong improvement of water quality in relation to the nutrients removal. Meanwhile, the University of Extremadura also detailed the positive results of OptimEDAR at the Albuera WWTP (Extremadura, Spain).

An active round table was carried out at the end of the workshop. The main challenges and opportunities that the wastewater sector is facing nowadays in order to enhance energy efficiency and promote innovative technologies were the main subjects.

Successful follow-up of OptimEDAR project

July 2014

On 12th of June took place the follow-up meeting of the Eco-innovation OptimEDAR project.

The main aims of this event were the following up of the different milestones in order to guarantee the correct achievement of the technical and financial goals. In addition, as a part of this evaluation, one of the Spanish demonstration site was visited by the European Project Officer and the members of the international consortium.

As a result, the European Project Officer evaluated successfully the management and development of this wastewater European project.

Save up to 20% of energy and eliminate nutrients in WWTP

This strategic workshop, which will be hold in Barcelona on 3rd of July, aims to deal with the minimization of energy costs and maximize operation efficiency in wastewater treatment plants.

Efficiency strategies in WWTP will be shown, especially the ones achieved with European project OptimEDAR:

• 20 % reduction in the cost of the energy consumption of the biologic reactor.

• Enhanced water quality of effluents with at least 20% less nitrogen and phosphate.

• Reduction of 15% in the production of sewage sludge.

Evaluation of OptimEDAR’s Milestones

January 2014

The 15th of January took place at Adasa’s headquarters in Barcelona, the OptimEDAR’s consortium evaluation meeting. The main aims of this event were the following up of the different milestones in order to guarantee the correct achievement of OptimEDAR goals, not only the ones related to the technical aspects but also the financial indicators.

Furthermore, Adasa, the Catalan Water Agency, Ecotrust, and AMMi Technologies visited some of the Spanish locations where OptimEDAR has been installed, such as wastewater treatment plants of Masquefa and Gelida. OptimEDAR has been working in these WWTP for 3 month providing interesting data which underlines the efficiency of the solution in the improvement of WWTP operational conditions.

Sîntimbru WWTP

Apahida WWTP

In November Adasa and Ecotrust carried out the first installations and commissioning of OptimEDAR in Romania at the wastewater treatment plants (WWTP) of Sîntimbru and Apahida.

OptimEDAR aims to optimize WWTP operation in order to achieve proper regulation of the process by automatic corrections and adjustments, taking into consideration influent and environmental conditions.

These installations were developed successfully and the data analysis will help to improve plants conditions and reduce electrical consumption.

Commissioning of OptimEDAR Solution in Spain

Novemeber 2013

In September Adasa, with the support of the Catalan Water Agency (ACA), carried out several installations and commissioning of OptimEDAR solution in Spain at wastewater treatment plants (WWTP) of Masquefa, Gelida and Carme, placed in Barcelona.

The main work consisted in the installation of the probes in the biologic reactor and the installation, commission and control tasks of the probe cabinet.

The next step will be the analysis of the data achieved in order to improve WWTP’s operational conditions and reduce electrical consumption.

Green Efficiency Boost for Water Treatment Plants

Novemeber 2013

There are more than 65.000 waste water treatment plants in Europe, each providing an essential service to local populations. But by simply installing innovative new equipment, plants could cut energy use by up to 25 percent while increasing nutrient removal by up to 20 percent.

Engineers within the EU-funded project OptimEDAR ('Efficient Management of Small and Medium Wastewater Treatment Plants') are hoping to first demonstrate the feasibility of this new technology, and then to roll it out across Europe.

Leading the team is project coordinator Sergio de Campos from ADASA, a Spanish water and environmental monitoring company. The prototype, developed within a national research project, addresses current operational, regulatory and technical weaknesses that are reducing the efficiency of waste water treatment plants across Europe, De Campos explains.

Operationally, a plant is designed to deal with the average waste water flow and composition from the towns or city it serves. But the organic load changes regularly - from day to night, during weekends and between seasons. Some Mediterranean towns see their population increase threefold during summer, for example.

While output is sampled regularly, once a month, in line with EU regulations, the samples are not necessarily an accurate indicator of the plant's entire output. It is in everyone's interests to ensure quality meets the appropriate standards at all times.

At a technical level, all waste water treatment plants have a system to remove the nutrient and organic load. As small and medium-sized plants are not manned at all times, aeration engines are often simply switched on and off at specific times, or according to the readings picked up by a dissolved oxygen sensor.

"But we know from scientific knowledge of the processes inside the tank, and practical experience, that there is a minimum set of parameters that can be measured with non-expensive sensors. With these sensors, OptimEDAR calculates the equivalent organic load, and controls the aeration process according to this 'virtual' information," explains De Campos.

A prototype installed at a plant in Badajoz, Spain, was able to reduce the time that biological blowers operate each day from 14-16 hours to 5-6 hours, while enabling the generation of denitrification and dephosphation cycles. This ensures higher quality output.

Within the OptimEDAR project, the team is conducting case studies in Spain and Romania. The equipment will be installed at six different plants, giving the team the opportunity to assess whether the savings witnessed with the prototype can also be obtained in other environments.

Installing the equipment at different plants is already providing valuable feedback that will help the team revise its specifications so that the end product is suitable - or adjustable - for every small or medium-sized waste water treatment plant in Europe.

Research projects are looking into new treatment processes that would lead to the building of new plants or new process lines in existing plants. This would be a major investment.

What the OptimEDAR project is trying to do, on the other hand, would not require significant funds - the project's objective is simply "to get thousands of existing plants to run properly", says De Campos.

OptimEDAR ends in July 2014 and received around EUR 600 000 in funding from the EU.
