The demand for these technologies, innovations, and products is on the increase as a result of the demand for an alternative water source. than conventional filtration systems and is well suited to a variety of water processing needs.
Euglena biofiltration system
Euglena is an aquatic organism that absorbs water pollutants. With this characteristic, Canadian company Noble Purification has developed a filtration system to treat water, using controlled algae to bloom in wastewater, which absorbs toxins in the water. Noble Tech Inc. researches, cultivates, and markets unique microalgae strains and their derivatives for various market applications, from wastewater treatment to nutritional products and, eventually, pharmaceuticals.
Graphene aerogel
Researchers at the Chinese Hubei University have designed a graphene aerogel film that, through using only sunlight, can produce water vapour at room temperature. The team explains that the aerogel floats on the surface, where it heats up only a small part of the water column,“ while the temperature of the bulk water is far below the boiling point.”
Where fuel or access to electricity is limited, this sunlight-harvesting graphene film could convert seawater or wastewater into drinking water. Desalinating seawater to make it drinkable usually means boiling it and then collecting and condensing the steam.
The team showed that under simulated sunlight, the aerogel could heat up 100ml of water to 45 ° C, about 13 ° C higher than water without the aerogel. The material’ s porous structure pumps the generated steam away from the surface, allowing water to evaporate 13 times faster than it would without the aerogel.
A downside, however, is the durability of the film for use in a desalination device, as it is currently easily broken when picked up.“ I do not see fundamental difficulties in bringing the current technology into real life applications, although much more feasibility studies should be done,” adds a member of the team. u
