RAS Technology Systems

 

Technology proven in both freshwater and marine closed environment RAS systems that is fully adaptable for use with commercial water, low or poor freshwater or seawater supplies, providing reduced exchange rates and high quality water intake thru proven water pre-treatment filtration programs and recirculation water waste management.

Innovative  technology and  basic SOPs (Standard Operating Programs) associated with the Barrablue Technology that ensures economic returns, at all times conserving, maintaining and protecting the natural environment and minimising depletion of our natural water resources.

BBA’s RAS technology received acknowledged for Australian Government EPA with respect that it in that water discharge exceeded both Australian and World Fisheries EMP guidelines affording the highest levels of protection to the natural environment.
 
Achievable and realistic bio-mass stocking densities up  to 80 kg/m3 (naturally aspirated- dependent upon species)  with upper limit of 120kg/m3 for oxygen induced systems meet environmental waste management guidelines  and  guarantee  economic returns.

BBA systems   operate under strict bio-secure practices eliminating cross contamination, reduce disease risk. BBA’s   biologically filtration maximises de-nitrification combined with protein Skimmers, passive fluidised filtration (all non-mechanical or energy driven) and high density UV water sanitisation. Reduce energy operational costs

 

HYDROPONICS (AQUAPONICS)

Hydroponics (Aquaponics) added further assist de-nitrification process by the uptake of ammonia and nitrites, thus allowing water to be continually recirculated, further reducing daily water exchange and energy costs.  

BBA’s water management provides where applicable water recirculation through hydroponics (Aquaponics) facility whereby plants uptake  water rich nutrients  reducing ammonia & NH3 levels within the system ensuring additional contribution to  overall de-nitrifying process.

By example 6000 edible  salad vegetables as in lettuces/Tomato//Capsicums/Flowers/herbs) plants can be grown using 5,000liters  per cycle/hour of recirculated water  contributing further to maintain water exchange rates as low as 1-2% per day.
