SEMINAR “Water in the Mediterranean region”

Friday  22nd June –  ITS VESPUCCI

Main Theme

“Water in the Mediterranean region”

Organized by DLTM, Universidad de Las Palmas de Gran Canaria, University of Sfax, Suez Canal University, Université Sidi, University College Dublin – Marine Technology Society 

Executive Summary

Can drinking water be a renewable resource? Dual use and water management. Water is called “blue gold” because it is a precious, althougth limited, resource. Nevertheless it is fundamental for our life and for the natural equilibrium always linked to our subsistence. An unavoidable “virtuous” circle, which, due to climate change, the increase in the world population and the consequent exploitation of this resource is seeking for a new balance.

Whether they are real engineering jewels or prototypes in search of funds, there are more and more technologies designed to have clean and drinkable water available to solve the current water crisis. There are many solutions that try to solve the problems related to water scarcity, especially in arid countries or where drinking water remains a mirage such as: technologies for the recovery of gray waters and desalination (with 70% of surface of the planet covered with water, desalination of seas and oceans could be a turning point for global water emergencies).

Moderator: Lavinio GUALDESI (LAVIMAR).

Period Time Item/Speaker

13.10 Michael MAX (University College Dublin | Marine

Technology Society) – NEW TECHNOLOGICAL

SOLUTIONS: Create new high quality water.

1)               The chemical engineering approach to seawater desalination  Use the CO2 emitted by the plants and confine it in abysmal tanks (abyssal confinement of the Kyoto protocol).

Fresh water produced by the crystallization of sea water with CO2 hydrates.

2)               Condensation of water from the air with a sustainable and high efficiency procedure (CWA-Tech)

Brief history of the HERSE team and its application to address water problems

 

Period Time Item/Speaker
13.00/17.00 13.50 Abdelhak KHERBECHE (Université Sidi Mohammed Ben Abdellah) – Water management in Morocco.

For years, Moroccan research laboratories have been working on catalysis and on new eco-sustainable materials (LCME) in association with European and North African partners. Among the objectives: the research of innovative techniques for water treatment, the photo-disinfection of natural waters by means of photo-catalysis, catalysis through oxidation in a diluted aqueous medium, as well as the development of less expensive and more performing seawater desalination processes.

14.30 Michael P. MAX (University College Dublin – Marine

Technology Society) – Water from the Air.

Extract the water from the air using a new high energy efficiency condensate designed to work with renewable energy. The water produced at the point of use, no transport, competes in terms of quality with bottled water, minimum conservation / treatment requirements, concept of energy and water.

Sustainable housing

Sustainable villages

Transportable systems (ships)

Water transport problems

Disposable water bottles are expensive and non- environmental

Shortage of drinking water

Technology: Specific condensation evaporators.

Specific thermodynamic models of condensation to control energy efficiency according to the production of water.

Renewable energy-water solution.

14.50 Amel HAMZA CHAFFAI (Sfax University) – The battle for water for a better quality of life.

Tunisia is less endowed with water resources than many other Mediterranean countries. The water potential is controlled by a very unbalanced geographical distribution and a strong interannual variability. In recent decades, water has become a decisive factor in spatial planning and economic and social development. The analysis and monitoring of surface and ground water are necessary to ensure the quality of water for human consumption and agriculture. Some areas with limited water resources have a high humidity (67% -75%). The extraction of water from the air through a new highly energy-efficient condensation has the potential to provide a solution to local water shortages.

 

Period Time Item/Speaker
13.00/17.00 15.10 Michael P. MAX (University College Dublin – Marine

Technology Society) – Closed Agriculture (EnAg).
Manage the CO2 / gas balance of greenhouse agriculture to optimize food production with well-balanced nutrients and growth (for plant quality without sacrificing growth rates). Controlled plant growth consumes CO2 and produces oxygen through growth photosynthesis. The carbon sequestered by the accelerated growth of plants is both food and solid waste. EnAg buildings near the sea can also produce irrigation water using passive solar heating. The use of solar as an energy source for EnAg coordinates the normal growth times of plants, creating further energy availability. A fraction of positive energy is stored in the batteries by necessity during the night. At night, plants convert oxygen into CO2 through a process called breathing. Breathing can be minimized while CO2 consumption can be maximized.

Technology:  Application of CWA-Tech

Infrastructure and adaptive practices for CWA-Tech.

Thermodynamic models for plant growth (specific for individual plant species)

Control of gas levels and injection / extraction to maximize growth and minimize CO2

Scientific / economic model of all pre- and post-growth processes.

15.20 Mohamed TAWFIC AHMED (Suez Canal University) Water scarcity in Egypt, the search for sustainable solutions. Introducing sustainable water production from the

environmental point of view from the abundant and renewable atmospheric humidity reserve. This would also include the use of advanced technologies, including hydration-based methods to recover wastewater as a sustainable approach to increasing water scarcity in Egypt. This presentation highlights Egypt’s water footprint, water resource profile and approaches used to promote sustainable use water. It also examines the possible challenges that the new Grand Ethiopia Renaissance dam could represent for Egypt.

15.50 Jésus CISNEROS AGUIRRE (University of Las Palmas de

Gran Canaria) Water treatment.

Use the same polluted CO2 from power plants to compress and purify contaminated water and wastewater. Use of other technologies.

16.10 Final Discussion
