Depollution of water containing hardly biodegradable organic compounds (endocrine disruptors) by advanced oxidation processes using innovative catalysts

OXYDEP

PN-III-P2-2.1-PTE2016-0063 (8PTE/2016)

Endocrine disruptors (ECDs) are synthetic chemicals that mimic the function of hormones and, once in the body, alter the hormonal balance. The source of these endocrine disruptors is diverse, coming from synthetic products used or resulting from the most diverse branches of the economy. We are talking about: dioxins, parabens, bisphenol A, phthalates (plastics industry), organic insecticides, etc. Important sources of endocrine disruptors are compounds from pharmaceuticals and personal care products (PCPs).

Project goal

The aim of the OXYDEP project is the transfer of a water depollution technology containing hardly biodegradable organic compounds (endocrine disruptors) to an economic agent with a solid tradition in the development, implementation of technologies and production of systems for water depollution and treatment.

General objective
  • A new approach to advanced oxidation processes (AOP), in order to reduce energy consumption, to obtain the most complete mineralization of pollutants, thus transforming the AOP into a process successfully transferred to the industrial level. The approach involves the use of innovative catalysts in catalytic ozonation processes, resulting in reduced operating costs, capital costs, increased environmental performance and energy efficiency of the depollution process.
  • An optimization of the synthesized catalysts (by studying both the optimal support materials and the active component), both to align the technology with the latest studies worldwide and to ensure a successful transfer to the economic agent.
  • Approaching a wide range of applications in the field of water treatment, both waste and drinking water, depending on the application can be configured for: industrial wastewater treatment for treatment or recirculation for technological purposes, integration into conventional treatment steps to remove non-biodegradable organic pollutants and increasing the degree of biodegradability, decontamination of water from contaminated sources and used for the production of drinking water, use in emergencies or hazardous situations.

Phase III

Demonstrating the efficiency of technology in the industrial environment

Implementation period: 16/12/2017 - 03/07/2018

Activities carried out:

  • Prototype production
  • Prototype experiments in order to optimize the operating parameters
  • Demonstrating the efficiency of the technology implemented in the industrial environment, by characterizing the post-treatment waters
  • Characterization of post-treatment catalytic materials
  • Elaboration of the final technical specification
  • Dissemination of results
Obtained results

Within the project, the prototype of the depollution module was made, which was installed within the Municipal Water Treatment Plant Bistrita, where it was tested in real operating conditions on water samples from the technological treatment flow.

The technological flow related to the water depollution module containing hardly biodegradable organic compounds includes water-ozone contact steps and the catalytic reactor, followed by the adsorption filter. This module is configured in such a way that it can be operated both with immobilized catalytic bed and in a fluidized environment. The module can operate both in INPUT-OUTPUT mode and in recirculation mode.

The demonstration of the efficiency of the technology was made by characterizing the pre- and post-treatment waters. Its viability was also assessed by characterizing the catalytic materials before and after the water treatment stage.

The project resulted in the patent application "Process for water treatment with content of hardly degradable organic pollutants" - A / 2017/01032, Authors: Sorin Claudiu Ulinici, Sorin Marius Avramescu, Radu Claudiu Fierăscu
