Treatment of water from sources contaminated with nitrates and chlorinated organic compounds using integrated catalytic reduction / oxidation and biofiltration processes

DENOX

PN-III-P2-2.1-PTE-2019-0222 (26PTE/2020)

Pollution of water sources with nitrate ions and chlorinated organic compounds (COCl), such as some pesticides or their degradation products, is a major problem, especially in areas where intensive agriculture is practiced.

Project goal

The goal of the project is the transfer and development of a technology for depollution of water from sources contaminated with nitrates and chlorinated organic compounds (pesticides and their environmental degradation products), efficient and economically feasible, which can be used to obtain drinking water and / or for the remediation of groundwater bodies.

General objective


The general objective of the project is the transfer and development of a technology for depollution of water from sources contaminated with nitrates and chlorinated organic compounds (pesticides and their environmental degradation products), efficient and economically feasible, which can be used to obtain drinking water and / or for the remediation of groundwater bodies. The transfer will be made to an economic agent with important activity in the development, implementation of technologies and production of water treatment systems (ICPE Bistrița SA), in partnership with an economic agent with sustained activity in promoting and implementing technologies to beneficiaries (AKRO SRL), in order to increase economic competitiveness.

Specific objectives
  • Documenting the transfer at an industrial scale of the validated laboratory technology and identifying the possibilities for optimizing the proposed technology (functional, operational and in terms of energy consumption), by aligning with the latest scientific discoveries in the field, in order to ensure the success of the transfer;
  • Transfer and optimization in the industrial environment of the proposed technology;
  • Validation of technology efficiency by independent entities;
  • Demonstrating the efficiency of the technology implemented in the industrial environment.
Phase I

Preliminary activities for the validation of the proposed technology at industrial level.

ICECHIM activities:

  • Analysis of the morphological and structural properties of the obtained catalytic systems;
  • Results dissemination.
Phase II

Validation in the industrial environment of the proposed technology.

ICECHIM activities:

  • Experiments in order to evaluate the efficiency at the industrial level of the catalysts, their optimization and the optimization of the technological parameters of the functional model;
  • Results dissemination.
Phase III

Demonstrating the efficiency of the proposed technology in the industrial environment.

ICECHIM activities:

  • Characterization of the catalytic complexes before and after treatment;
  • Elaboration of final technical specification for the integrated technology demonstrated at industrial level;
  • Results dissemination.
Results dissemination
