An innovative Australian technology that uses bubbles to remove contaminants from water offers a solution to an emerging global pollution crisis-microplastics. The technology belongs to EVOCRA, an Australian water treatment company that was formed in Tasmania in 2011. The patented process, known as Ozofractionative Catalysed Reagent Addition or OCRA, literally floats the microplastic out of the water where it is collected and sent for recycling. EVOCRA's Managing Director Mark Sykes says OCRA is a solution for many water-based environmental challenges. "Microplastics are plastic items smaller than 5mm that are found in everyday products such as sunscreen, shampoo and detergent. Too small to be filtered out in the treatment plants, they wash into waterways where they harm our aquatic wildlife," he said. "OCRA offers a positive solution to this complex environmental issue. The technology can be applied as a pre-treatment, that is, before the plastic enters the sewerage system or at the treatment plant to remove the particles before discharge."
