Around 80% from wastewater treatment plants in the EU have secondary treatment processes using activated sludge. Municipal sewage plants rely on the eﬃcient and continuous processing of eﬄuents to avoid the release of untreated wastewater and subsequent environmental and public health threats. Uncontrolled spills containing harmful substances can damage the biological units, since an increase in the toxic load of urban wastewater reduces the cleaning capacity of the bacterial culture. Such harmful increases come from uncontrolled discharges with excess toxic loads and can be seasonal. Consequently, untreated water can be released, contributing to the loss of biological diversity and degradation of water resources.
When a treatment plant operator detects that the organic or nutrient removal performance is decreasing, most of the biomass has already been damaged. The usual procedure to resume normal activity consists of increasing the air supply to the bioreactor. Considering that aeration systems can represent around 50-70% of the total energy consumption of a WWTP, an increment in energy requirements in the biological process will lead to a considerable increase in the overall energy consumption at WWTPs.
In this context, the general objective of BACTIWATER is to demonstrate that the proposed tools can reduce the environmental impact of failures and malfunctions at biological units after spills.
The whole project, including the experimental phase, will take place in Valencia (Spain).
BACTIWATER is an EU ﬁnanced project in the framework of the Life Program, which is the EU’s ﬁnancial instrument supporting environmental and nature conservation projects throughout the EU.
BACTIWATER aims to optimize the active sludge process as well as to reduce energy consumption in case of pollutant spills that could reach the WWTP and affect the biological treatment. Considering that aeration systems can represent an important amount of the total energy consumption of a WWTP, an increment in energy requirements in the biological process will lead to a considerable increase in the overall energy consumption at WWTPs. It is expected that the use of BACTIWATER project results will decrease the energy consumption.
The specific objectives of the LIFE BACTIWATER Project are:
Environmental protection from wastewater discharges and compliance with the Water Directive 91/271/EEC, ensuring that the quality parameters in the effluent of the WWTP remain below the limits established by the Directive, avoiding harmful environmental impacts.
Economic and environmental evaluation of the recovery of the biological process through the use of BACTIWATER after several artificial spills on a pilot scale
Validation of an early detection diagnostic kit for malfunctions in the biological process
Elaboration of prevention and correction protocols for biological treatment failures in WWTPs
Promotion of new omics tools as diagnostic methodologies in wastewater treatment control
REDUCTION OF ENERGY CONSUMPTION
Reduction of energy consumption in the regeneration process according to the European target of 20% increase in energy efficiency by 2020
Contribution to the European water innovation strategy
Development of a knowledge base to support beneficiaries and stakeholders with future water treatment regulations
Dissemination and transfer of the project results to the interested parties to ensure the sustainability and transferability of BACTIWATER methods
Elaboration of an exploitation and commercialization plan for the project results
A. PREPARATORY ACTIONS
A1. Spill database and historical analysis
This project phase has a duration of two months (from September to October 2017) and deals with the compilation of discharge events at the Quart Benàger WWTP during the last 10 years, the historical database updating, as well as the determination of the most relevant microbial profile in the nitrification and denitrification process. In order to determine the most favorable bacterial profile for BACTIWATER, the influence of external factors such as climate, season, temperature and geographical location will be strongly considered.
B. IMPLEMENTATION ACTIONS
Action B includes the adaptation and commissioning of the demonstration plant for the development of the trials. The duration of actions B comprises from the beginning of the project in September 2017 until the end of project in February 2020.
B1. Demonstration plant adaptation and commissioning
The objective of this action is the adaptation and commissioning of the pilot plant where the trials will take place. During the project experimental stage, it is expected to assess how the contribution of different microbiological cultures can improve the biological process considering the effluent quality and energy consumption from the aeration equipment.
The pilot plant is located in the WWTP of Quart-Benàger and was built using the structure of an existing plant, after having checked and adapted the equipment. Furthermore, a new equipment was to guarantee the significance of the results obtained.
B2. Manufacturing of microbial enhancers
In this phase, microbial cultures have been selected as well as the most favorable culture and nutrient medium for the nitrifying and denitrifying bacteria of the biological system.
B3. Experimental phase
According to the historical discharges occurring at Quart Bènager WWTP, spills are divided generically into four types: surfactants, pesticides, heavy metals and organic load increases. Due to this type of compounds and that they usually affect the processes of many other treatment plants (not only in the Valencian Community but also at national and European level), the time reduction for the recovery of the process will be demonstrated through the addition of the bacterial preparations obtained in activity B2.
B4. Implementation of an early detection protocol
The objective of this project phase is to develop an early detection kit of biological malfunctions based on PCR techniques. Specific primers will be designed to detect bacteria or a group of bacteria that can act as markers.
B5. Business plan
A business model will be developed to establish the foundations of an exploitation plan that will take into account current market strategies, profitability and patentability.
C. MONITORING OF PROJECT ACTIONS IMPACT
This project action deals with the evaluation of the technical-economic viability of the project results with the aim of a future commercialization. The duration of stage C includes from the beginning of the project in September 2017 until the end of the project in February 2020.
C1. Environmental and economical feasibility
This phase of the project deals mainly with the economic analysis that will determine the total costs, as well as the evaluation of the economic viability. Different methodologies will be used, such as Life Cycle Cost Analysis and Techno-Economic Evaluation.
C2. Monitoring and measuring of LIFE performance indicators
During the project impacts monitoring, the following indicators will be considered: reduction of CO2 emissions, better use of natural resources, reduction of the energy consumption, acceptance in the market, communication and dissemination of project results.
Water and energy consumption will be strongly considered during the production of bacteriological enhancers as well as the use of recycled wastewater during the project.
D. DISSEMINATION AND COMMUNICATION OF RESULTS
D1. Dissemination planning and execution
During the project development, the dissemination of results, status of the project, as well as the development of social networks will be carried out. Through the dissemination of the main project results and lessons learned at national and international level, it is expected to raise the awareness of stakeholders and demonstrate the effectiveness of BACTIWATER results. These results will be communicated and disseminated to the most relevant stakeholders through different methods.
As a part of the dissemination plan, a Notice Board and several leaflets have been printed and distributed. The first BACTIWATER leaflets were distributed at the EFIAQUA water fair held in Valencia in 28-30 th November 2017.
