Water Filtration Now at 1000x Less Energy

A new water filtration technique, developed at Princeton University by Dr. Orest Shardt and Dr. Sangwoo Shin, promises to cut the energy consumption in water filtration to a thousandth of the consumption needed for conventional water filtration mechanisms. The technique uses carbon dioxide, to which the colloidal suspension is exposed.

This technique could replace popular microfiltration and ultrafiltration techniques. Conventional water filtration techniques require a membrane, which often gets fouled after repeated exposure to the colloidal solution. The new technique avoids the need for a membrane, greatly enhancing the structure of the water filtration mechanism.

Rising Need for Clean Water Ensures Steady Demand

The rising need across the world for clean water, for personal as well as industrial uses, is likely to drive the demand for highly effective water filtration techniques. Booming sectors such as food and beverages, mining, and pharmaceuticals are major consumers of clean water, sustained demand for which is thus likely in the coming years. The rising population and prosperity of emerging regions such as Southeast Asia and Latin America are likely to boost the prospects of the food and beverage and pharmaceuticals markets, which will enable a steady rise in the demand for water filtration techniques. This could also lead to rising use of the technique in human water consumption and wastewater treatment.

Added to the high efficacy of the new water treatment method, it can also be easily scaled up, according to its developers. This will enable its steady production at an industrial scale in the coming years. Success in implementing scaled up operations is likely to play a crucial role in the establishment of a global market for the new technique.
