VorTech Water Solutions (VWS) solves energy intensive municipal and industrial wastewater treatment. Wastewater treatment has a massive energy footprint, consuming 1-2% of the world’s electricity. This is being continuously intensified by population growth and increasingly stringent treatment regulations. A significant contributor to the energy demand is the aeration process in biological treatment, accounting for up to 1% of the world’s electricity, which continues to employ outdated and inefficient aeration technologies. Energy efficiency has never had sufficient focus in the design of aeration systems. The Vortex Power Aerator, a novel wastewater aeration technology that massively reduces the energy of wastewater aeration has been developed to reduce the footprint of these processes. VorTech Water Solutions specialises in providing energy efficient water and wastewater solutions together with high-value services such as computational fluid dynamics and process modelling to maximise treatment performance at the lowest energy input. With years of expertise in fluid dynamics, wastewater process, control, and energy, we have developed the Vortex Power Aerator, cyclonic aeration approach which massively reduces the cost of aeration by up to 50%.
