Frequently Asked Questions
Q. Why are the Aquaconsult diffusers so efficient?
A. Simply by producing a much smaller bubble than any other type of membrane. The smaller bubbles present a greater surface area for oxygen exchange for any given air input.
The unique design also allows for reduce pressures, which in turn allow for smaller pipe diameters and reduced costs on blowers, valves and other hardware.
Q. What is the relationship between Aquaconsult and Hydrok
A. Hydrok are the sole distributors for the Aquaconsult range of products in the U.K and Eire.
The Hydrok process has been developed using the Aquaconsult membrane, and has been designed to optimise the efficiencies that it can offer. When the Aquaconsult membrane is used in conjunction with a Hydrok design and build package then maximum efficiency is achieved.
Q. How are oxygen transfer efficiencies of 60% achieved?
A. The main reason is the greater surface area that is present for any given volume of air.
Q. Why is there a variation in aeration efficiency?
A. The aeration efficiency can be increased simply by adding more diffusers, therefore, our designers can manipulate the number of aerators to meet the client's requirements. Reduced efficiency will result in lower capital costs, whilst an investment in additional diffusers will result in increased efficiencies and lower whole life costs. Our designers will provide several cost options allowing for an economic balance between capital expenditure and future operational costs.
Q. How can operational costs be reduced so much?
A. The lower energy costs are a result of good design, other operational costs are reduced by introducing automatic maintenance cycles within the operating philosophy. These include deflation cycles that remove organic growth, and acetic acid dosing that cleans the membrane pores as and when required.
Complete maintenance packages are available, along with sampling points that allow for the inspection of diffusers without draining the tank. These options considerably reduce the need for man entry into tanks for maintenance purposes.
