Aeration

Fine bubble aeration is a simple process, but one that consumes 0.481% of
the total power generated within the United Kingdom. Therefore any efficiencies
that can be found to reduce this demand make sound commercial and environmental sense.

Hydrok can provide significant reductions in energy consumption, along with reduced
whole life costs and very competitive capital costs.

At the root of each Hydrok solution is an Aquaconsult AEROSTRIP^® diffuser.
This range of ultra fine bubble diffusers transfer oxygen to effluent more effectively
than any other type. This efficiency allows the designers at Hydrok to reduce blower
sizes, reduce air main diameters, and make savings on valves and other hardware.
Energy efficiencies in the range 40% over existing systems are being provided. By
adopting the combined Hydrok/Aquaconsult solution, immediate cost savings can be
gained, or perhaps more significantly, existing plants can be upgraded – with the
increased efficiency the capacity of an existing plant can be increased, sometimes
eliminating the need for costly civil structures or new sites.

The operational life of an Aquaconsult 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, and man
entry into tanks for maintenance purposes is avoided.

The increased efficiency of the Aquaconsult AEROSTRIP^® 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. However, increased efficiency is also provided
due to the general arrangement of the diffusers and the fact that they are secured directly
to the tank floor; this increases contact time, and the curtain effect of the bubble pattern
avoids dead areas.

Hydrok, who are proud of their association with Aquaconsult, are looking forward to making a
significant contribution to the reduction in carbon emissions.
