When waste water freezes, it is purified
Freezing technology can be utilised in waste water treatment. When waste water freezes, it is purified through the formation of a cleaner layer of ice. The clean layer of ice can be removed from the rest of the waste water. The new energy-efficient method of purification is based on the natural freezing process of water: energy is required only for breaking the ice and transporting it from the waste water pool.

Women need not justify their place in the technology industry
"Women are no longer an anomaly in the technology industry, although we speak of them as if they were. We noticed that there were fewer women than men in the technological fields and decided to correct the matter. However, I will venture to claim that the matter does not need to be corrected and as an engineer I trust the figures", states Riina Salmimies, LUT Director of Research and Innovation Services.
