Obiettivo del progetto (Objective)
'The rapid introduction of nano-based products into the market has caused a major concern both for health and environmental impacts, among others from the paint and coating business. A number of studies have documented health risks related to nanoparticles, inhalation exposure and dermal contact being main exposure routes in the coating and paint industry. Likewise, discharge of nanoparticles into aquatic environment causes damage to the gill membrane of fish and crustaceans. Today, the only effective means of removing nano-particles from water is application of energy intensive methods such as reverse osmosis. Therefore, the coating industry that uses products with nanoparticles needs a cost effective technology for removing them from used water.
The proposers of NANOFLOC have thus identified a new market opportunity in developing a novel electro agglomeration technology for removing nanoparticles entrained in water. The technology is cost effective, compact and nvironmentally friendly. It is based on destabilisation of nano suspensions and agglomeration of charged particles in solutions using electric fields and flocculation in one step, avoiding addition of chemicals. The objectives of NANOFLOC will be attained by development of innovative reactor for agglomeration and stabilisation of flocs, superior hydraulic design of a reaction chamber and creation of intelligent process control system (PCU).
The RTD work is structured in 5 of 8 WPs: In WP1, a life cycle analysis will be undertaken to provide a benchmark for the development program. Scientific characterisations of the process and development of parameters will be performed in WP2. Design and configuration development of the reactor will be carried in WP3. The PCU will be developed in WP4. The NANOFLOC system will be integrated and tested in WP5. Demonstration activities and dissemination of results will be carried out in WP6 and WP7 respectively, while project management tasks will be included in WP8.'
Introduzione (Teaser)
Nanoparticles are gaining popularity due to their versatility but the wide variety of potential applications presents both opportunities and challenges. An EU-funded project is developing a system that can remove them from industrial wastewater to address health and safety concerns.
Descrizione progetto (Article)
A major concern is the effect of breathable nanoparticles with dimensions smaller than 100 nanometres that are found in products like paints on health.
There are also fears that the discharge of these nanoparticles into rivers and streams could be toxic for living species, damaging the gill membrane of fish and crustaceans.
Currently, the only effective means of removing nanoparticles from water is through the application of energy intensive methods such as reverse osmosis.
This is a water purification technology based on the use of a semi-permeable membrane.
The http://www.nanofloc.org/ (NANOFLOC) project aims to develop a system based on electro agglomeration, capable of efficiently and cost-effectively removing nanoparticles.
The NANOFLOC system works by destabilising nano suspensions and agglomerations of charged nanoparticles in solutions by applying electric fields, thus avoiding the need for chemicals.
A lab reactor for the agglomeration and stabilisation of agglomerations has been designed and built, along with a reaction chamber and an intelligent process control unit.
This will be tested in the second reporting period.
To evaluate the designs, researchers have investigated different nanoparticles and selected two for testing: titanium oxide and aluminium flakes.
Tests on synthetic wastewater containing the selected nanoparticles were promising, showing 98 % reduction of nanoparticles' concentration after treatment.
A mathematical model of the agglomeration and separation process has also been developed to verify the results.By 2016, manufacturers will be required by law to use paints and coatings on their vehicles which supply resistance to corrosion and scratches.
The use of nanotechnology in this sector is therefore expected to grow exponentially.
Industries that extensively use nanoparticles will benefit considerably from such a cost-effective, compact and environmentally friendly technology.
