Fresh Water Aeration
The Aquaconsult AEROSTRIP® diffuser range of ultra fine bubble diffusers transfer oxygen more
effectively than any other type. They are are a perfect solution for clean water oxygenation applications
for use in rivers, reservoirs, rivers, lagoons and ponds etc where oxygen levels need boosting to maintain
aquatic conditions. This efficiency allows the designers at Hydrok to reduce blower sizes, reduce air
supply diameters, and make savings on valves and other hardware.
Energy efficiencies in the range 40% over existing systems are being provided. The increased efficiency of the
Aquaconsult diffuser is due to the very fine bubble that is generated – this presents a greater surface area for
any given volume of air to the flow compared to any other system. Increased efficiency is also provided due to
the general arrangement of the diffusers and the fact that they are sited directly to the river bed; this increases
contact time, and the curtain effect of the bubble pattern avoids dead areas. Aquaconsult have been designing and
building what are widely regarded as the best diffusers available in the market for a number of years. These diffusers
offer the optimal symbiosis between low capital investment and low energy cost on the one hand, and maximum
performance on the other.
The operational life of an Aquaconsult AEROSTRIP® diffuser is typically in the range of 14 – 20 years,
and with the unique way in which the membranes self clean, whole life costs are reduced.
Exceptional operating properties
- Flat design, allowing the AEROSTRIP® to be located directly on the floor of the river bed, lake or reservoir
- Water flow created by a mixer is not hindered by the diffusers, unlike a dome design
- No precipitations can occur underneath the diffusers
- Oxygen transfer efficiency up to 60%
- Aeration efficiency 3 to 5 kg O2/kWh
- 0 to 100% control of air flow range
- Non-clogging diffuser membrane
- Capable of intermittent operation
- Low maintenance requirements and costs
- Extended operational life expectancy
Oxygen transfer in clean water
The outstanding qualities of the AEROSTRIP® have been confirmed by numerous field measurements carried
out by Public Authorities, Universities and independent research institutes.
Flexibility
The diffusers can be designed to act as a permanent installation or can be used as a flexible temporary unit within the
Hydrok designed Diffuser Liftout Grids. These can be designed and made to the specific location requirements and are also
availble as hire units for emergency applications.
