Project objective
The development of innovative biotechnological procedures coupled with physical-chemical procedures for WWTP’s effluents and residual sludge advanced treatment with the purpose of obtaining the normed water quality for re-use
Specific objectives:
- Comprehensive study on physical-chemical and biological processes for wastewater and residual sludge treatment (efficiencies, quality, requirements) according to European and Romanian regulations;
- Development/evaluation of modern technological solutions for advanced wastewater treatment in order to reuse it as an industrial/ irrigation water source;
- Development of technological solutions for residual sludge treatment and reuse as agricultural fertilizer;
- Development of an eco-efficiency and sustainable development model for a municipal WWTP;
- Development of a technological network in the field of advanced treatment of municipal wastewater and reuse of the treated wastewater and residual sludge.
Novelty elements:
- Application of advanced oxidation, filtration and UV disinfection processes for municipal wastewater treatment or other processes specific for the removal of heavy metals from residual sludge;
- Optimization of conventional biological wastewater treatment processes.
Results/indicators
- Technical analysis of wastewater and sludge treatment flows in Romanian municipal WWTPs;
- Development of an updated database of processes used for treating municipal effluent in order to reuse it;
- Updated database on the possibility to reuse the WWTP residual sludge as agricultural fertilizer, according to Romanian and European legislation;
- Integrated biotechnologies with physical-chemical processes for the advanced treatment of municipal effluent in order to reuse it (advanced oxidation, filtration on polymeric materials, UV disinfection);
- Residual sludge stabilization through anaerobic digestion and composting processes;
- Development of an IT-web based technological network: e-aparefolosire;
- 14 scientific papers presented at national (9) and international (5) conferences; Publication of 7 scientific articles in ISI quoted journals.
Post-Project actions
- Development of a research and development network for projects that follows the integrated approach of wastewater/residual sludge treatment and reuse complex problem;
- Partnership between research and WWTPs for dissemination, valorization and operative implementation of the research results;
Beneficiaries:
- Municipal WWTPs
- Central and local administration offices for environmental monitoring and control;
