Aqua Biofilter offers Aquaponics Home Systems, Floating Wetlands, Floating Reedbeds and Floating Habitat Islands.
Biomimicy of natural systems allows nature to be restored to a state of balance, benefiting human health and wellbeing by purifying water that we enjoy for drinking, bathing, showering and recreation. Wetlands are the kidneys of the landscape, purifying and cleansing waterway pollutants, heavy metals, and excessive nutrients. Often wetlands and ponds accumulate excessive sediment, nutrients and pollutants whilst water quality declines, algal blooms and aquatic weeds proliferate reducing biodiversity. Restoring ecological function and bio-signal activity requires natural systems that mimic peak ecosystems - which led us to design and development the Aqua Biofilter Floating Wetlands in 2004, to improve water quality beyond existing methods for ponds, wetlands and waterways.
Tom's background in permaculture and environmental management led him to teach Permaculture Design Courses from 2002 onwards with the co-founder of Permaculture David Holmgren and other well known designers, specialists in Regenerative Agriculture (Regrarian) Darren Doherty, Permaculture Designer and Teacher John Champagne, whilst keeping in close contact with his teacher Geoff Lawton founder of the Permaculture Research Institute. Since 2000 Tom has been building aquaponics systems in largescale and small scale aquaculture systems across Australia and China. His projects include the largest aquaponics systems in the world, covering in some cases, hectares of aquaculture pond and lake with edible plants. Tom's creativity in large scale aquaponics aims to upcycle nutrients on a large scale for ecological, social and economic benefits. This experience led Tom to further refine his aquaponics home systems that incorporated all the accumulated knowledge and design smarts, into aquaponics home systems that utilise fish waste and produce food at a home micro-scale. Tom believes growing food at home is one of the most important things people can do for the planet and their own health,by reconnecting to locally grown healthy food and community.
Aquaponic floating wetlands pictured above was installed over severalhectares of aquaculture zone in Lake Taihu, China. The aquaculture was being impacted by stormwater and cross contamination with effluent, whilst fish waste led to ammonia build up and exacerbated algal blooms. Canna lily feature an edible rhizome with carbohydrates, whilst in the project below, wheat is grown in urban waterways and canals in a new residential area of Nanjing. Experimenting with food crops, wetland species, native sedges have led to in depth knowledge of plant - fish interactions, growth cycles and smart design principles to accelerate plant growth and purify water quickly. It should be noted that food suitable for human consumption must be grown in water that is pure, hygenic and with appropriate levels of nutrients. Experimental approaches to large scale aquaponics has yielded design insights that have been incorporated into unique aquaponics home systems that grow food safely in your home, by recycling fish nutrients to grow your herbs, salad greens, wheat grass year round.

Above project rice aquaponics growing on fish ponds to remove excess nutrients and provide and economic return for farmers. Social benefits include reducing nutrients and pollutants impacting receiving waters, lakes the marine environment, and enhancing humanand fish health outcomes.
Above project growing over a hectare of rice on fish ponds aquaponically to reduce ammonia and nitrogen, producing 20% more rice 15% faster than conventional rice paddy.
Advanced Biofiltration Research and Technology development has been an emerging science for the last 30 years. Installations
in Australia and China have demonstrated the feasibility of the technology, and its applications in aquaculture, stormwater treatment, sewerage
and on-site sewage treatment, industrial effluent treatment, often
for water re-use.
The Aqua Biofilter is an advanced Floating
Wetland treatment technology that can be utilised within a Wetland
Treatment Train either retro-fitting or designed into future wetlands. Detention basins can be designed
larger & deeper, effectively providing more storage and HRT.
Wetlands can also be sized smaller as a result, bringing down costs, achieving best practice and effectively treating TN, TP,
TSS and reducing heavy metals. Ecological and human health can benefit from floating wetlands, and biomimicy of natural systems restores natural balance.
