This website provides public information about the Nanofloc project. Nanofloc was initiated by the coordinator, Westmatic AB, and funded by the funding scheme 'Research for the benefit of SMEs' within the EU 7th Framework Programme.The Nanofloc project will develop electro-agglomeration and separation of Engineered NanoParticles from process and waste water in the coating industry.

Official start date of the project was 1 January 2013. Project duration is 24 months

Project Description

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 demage 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 need a cost effective technology for removing them from used water.

Project progress and technological achievements

Life cycle analysis

The first stage of the planned life cycle analysis (LCA) aimed at conducting a streamlined LCA has been completed. In this initial analysis, the goal and scope have been defined as precisely as possible according to the initial knowledge obtained during the first months of the project period. Further, a preliminary life cycle inventory (LCI), has been carried out in which the relevant inputs and outputs of the NanoFloc technology in the foreground system have been identified. 

5M Consortium and Technical meeting

The meeting was held at Fraunhofer, Stuttgart on 8th May 2013. The following picture shows partners from TI, Fraunhofer, Westmatic, Bamo, Melotec and Asio. It was decided at the meeting to focus initially on the ENPs – Titanium dioxide, representing a common inorganic ingredient in base coatings and Aluminium flakes, representing a metallic ingredient in base and clear coatings. The consortium was shown around the different instruments which can analyse nanoparticle size, distribution and element type in water. In addition they viewed the Renaren and another potential electocoagulation reaction chamber.
