Envisage NS
is working with a number of partners in water recycling demonstration projects
which are supported by the Smart Water Fund. The projects aim to develop and
implement recycling technologies to achieve water savings, including
- Removal of colour from recycled
water using photocatalysts – Titanium dioxide photocatalysts are being investigated
for removing color from waste water to increase the aesthetics of recycled
water for irrigation. Titanium
dioxide photocatalysts are able to remove some color from water that is
difficult to break down using traditional biological digestion methods.
- Recovery of caustic soda solutions
from industrial waste water – This project focuses on the recovery of
caustic soda solutions from waste streams using nanotechnology, as an
initiative to investigate ways of reducing the amount of caustic soda
being discharged to trade waste. Ceramic nanoporous membranes will be tested for caustic
recovery. This will reduce the
amount of sodium ions in waste water making the water more suitable for
irrigation.
 Purification and recycling of
water used by the Melbourne Aquarium – this project will demonstrate water
recycling within the aquarium, using nanomaterials and membranes. This initiative will aim to save
approximately 10,000 litres of water per week, and reduce salt water
discharge by up to two tonnes per week at the Aquarium. An educational program at the Aquarium
will also be included, in which an interactive Smart Water Wall will
provide visitors with a clear explanation of how the technology is applied
at Melbourne Aquarium.
