Within the framework of the Phase II of the project funded by #AECID, the PhD student of Haramaya University, Zewdu Bezu, in collaboration with the team of ICP-CSIC, presented on October 13th the Technical Report on the scientific study of the reusability of the saturated adsorbent zeolite in soil conditioning.
The event included an interesting presentation of the results obtained to date by the PhD student and the CSIC team, which will be completed in the field at Haramaya University. The presentation outlined the scientific
background and the experimental design to be conducted from November 2021 to July, 2022 in three successive harvesting trials. The president of the NGO, Francisco Moreno, and the Project Manager of the NGO in Madrid, Lourdes Ortiz, attended the event held in the ICP-CSIC, Madrid, Spain.

Phase II of the Defluoridation Project is launched by the team of the NGO ADS https://www.adsong.org/ together with the scientists of the ICP-CSIC https://icp.csic.es/profile/diaz-carretero-isabel/ and the company TAGUA https://tagua.es/
This Phase II of the project aims at evaluating the spent adsorbent based on zeolites, that has the fluoride trapped in a stable manner, in a new use as agricultural fertilizer. In collaboration with Haramaya Universtiy, in Ethiopia, a PhD student will evaluate the harmless use of this “waste” as soil conditioner in order to evaluate the efficiency in the fluoride entrapment by the zeolite. This Phase II will allow closing the cycle of the process, producing cero waste qualifying ad a circular economy technology.
A new donor has joined our project. In April 2020 we have signed a Collaboration Agreement with the Spanish Fundación General CSIC for one year.
CONGRATULATIONS! The plants have been officially Inaugurated.
Construction has started in Dida and Obe sites, under the supervision of Project Manager Dr. Taju Sani and the Head of the Salesians Mission, Aba Dido. Gutema, Abiyot, & Friends GC is responsible for the construction and installation of the two Fluoride Treatment Plants using Zeolite-based technology.
The service includes renovation of the Dida and Obe community water points. In Dida, a new faucet has been installed. In Obe a solar panel pumping system will be installed.
MSc. Dissertation Research, Loughborough University, UK
Mr. Dario Garcia Barrill is a student of MSe Water and Environmental Management at the Water Engineering Development Centre (WEDC), Loughborough University, UK. He has developed his own research dissertation on the topic of "Development of sustainable low-cost adsorption technologies for fluoride removal in Ethiopia". His research has focused on learning lessons from parts of Ethiopia where such technologies have been used. Under the framework of “Defluoridation in Ethiopia” project,
Dario spent time with Amigos de Silva, and the Salessians Missioners visiting the two sites aimed in our project (Dida and Obe). His results have allowed elaborating an entire water managing framework for our new installations. He has introduced our project at all levels, from the municipalities to the main stakeholders, setting the ground for future actions.

The Minister of Water, Irrigation and Electricity of Ethiopia, Dr. Eng. Seleshi Bekele has signed a Memorandum of Understanding with the NGO Amigos de Silva aiming to contribute in this implementation project. This collaboration agreement warranties that the zeolite-technology will be included in the Agenda of the Fluorosis Mitigation Project under the Water Supply and Sanitation Directorate.
Recently, a new donor has joined our project. In February 2018 we signed a Collaboration Agreement with the Spanish Foundation Juan Entrecanales de Azcárate for one year.
In June 2017 our project was initiated with the generous support of the Swiss Foundation Stiftung Freie Gemeinschaftsbank. It is a two year project to implement a new defluoridation technology based on natural zeolites, in Ethiopia.
The team formed by CSIC and NGO have visited the two project sites. All installations are functioning, including the solar panel in Site Obe. The facilities were handed over to the beneficiaries, the Salesians Mission.
Water points have been installed inside the school of Dida, and outside in the Community point. In Obe, water points are installed inside the Recreation Center. Local acceptance has already been confirmed by the teachers and guards, especially in Obe where women appreciate the substitution of the hand pump by the new solar panel driven pump.
