02 December 2014 - Aurecon’s Dr Dyllon Randall of the Water Unit, Tshwane, recently won 3rd place at the Falling Wall Lab in Berlin, for his work on wastewater treatment.

Dr Randall was one of 100 young scientists and professionals to present a creative solution to the social challenges of our time. The Falling Walls Lab aims to advance scientific and entrepreneurial visions and to initiate and promote exchange between young researchers and professionals across disciplines.

Dr Randall presented his work on using a novel technology called Eutectic Freeze Crystallisation (EFC) for the treatment of wastewater. Eutectic Freeze Crystallisation provides a more sustainable method for the treatment of highly concentrated wastewaters (brines). The work conducted by Dr Randall showed that up to 97% of a Reverse Osmosis brine can be converted into pure calcium sulphate, pure sodium sulphate, and pure water. The energy efficient process is capable of producing potable water, as well as a number of pure salts that the client can then sell for additional profits. The process ultimately converts a wastewater stream into useful products.

"Participating in the Falling Walls Lab competition was an amazing opportunity to meet like-minded people who also want to make a difference when it comes to some of the most pressing issues facing society,” says Dr Randall. The winners were selected by a high-calibre international jury from academia and industry under the direction of Professor Carl Henrik Heldin, Chairman of the Nobel Foundation, and Dr Martin Sonnenschein, Managing Director Central Europe at A.T. Kearney.

The three winners of the Falling Walls Lab also presented their breakthroughs at the Falling Walls Conference in front of 600 guests, as the ‘Falling Walls Young Innovators of 2014’. “The Falling Walls Lab is an outstanding example of effective science communication. It offers young researchers from all disciplines the opportunity to present their innovative research projects and initiatives to an international audience,” says Professor Jürgen Mlynek, President of the Board of Trustees of the Falling Walls Foundation and President of the Helmholtz Association.

“When we look back on the 25th anniversary of the fall of the Berlin Wall, we are not simply looking at the historical event of peaceful reunification. What are also fascinating are the tremendous opportunities and possibilities that arise when barriers are overcome. Only when we leave old ways of thinking behind and dare to try something new can innovation occur,” says Dr Martin Sonnenschein.
