»Electro-agglomeration and separation of Engineered NanoParticles from process and waste water in the coating industry to minimise health and environmental risks«
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. 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. The NANOFLOC consortium has 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 environmentally 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 a innovative reactor for agglomeration and stabilisation of flocs, superior hydraulic design of a reaction chamber and creation of a intelligent process control system (PCU).
