Greywater represents 40% to 60% of water usage in residential buildings such as hotels, apartment blocks and dormitories. It is the used water from showers, baths, hand basins and the laundry.
Australia has the most rigorous greywater recycling approval standards in the world and, with Nubian’s systems approved for use in every Australian mainland state, you’re assured of high performance.
Nubian’s technology is unique and its patented, chemical-free recycling system can deliver greywater to the most demanding “A+ Standard”. Meeting this standard means the recycled water can be used for internal applications such as toilet flushing & laundries and external applications such as above ground irrigation & vehicle washing
Proven, Government Accredited and Patented Technology
At the heart of Nubian’s domestic greywater recycling systems is a unique 3 step process:
1. Solids separation – which removes lint and other coarse materials to prevent blockages and malfunctions of the system
2. Biofiltration – a patented process which removes bugs and pathogens using a unique process that contains no chemicals
3. High dose ultraviolet (UV) disinfection – which attacks the DNA of bacteria, viruses and parasites causing them to lose their reproductive capability and destroying them
For the more demanding commercial environment Nubian’s systems use an additional 2 disinfection steps:
4. Ultrafiltration (UF) – which uses a membrane to remove pathogens and produce water with very high purity
5. Chlorination – which provides residual disinfection
These 2 steps, together with the UV disinfection, provide the required “Triple Barrier” protection demanded for “A+ Standard” commercial usage approval. Water treated by Nubian’s greywater recycling systems is of a high quality with BOD and Suspended Solids levels typically less than 5 parts per million.
All Nubian greywater recycling systems are automatic, chemical-free and require no intervention by the system’s owner. Nubian’s planned maintenance program together with an advanced, continuous on-line water quality monitoring system provides peace of mind for the system’s owner and for regulators.
Nubian systems are very compact and easy to install making them ideal for retrofitting in domestic and commercial buildings. They can recycle from 500 up to 100,000 litres of greywater a day.
