Our technology is based on the 'venturi effect'; the reduction in fluid pressure that results when a fluid flows through a constricted section of pipe, and rests on the well recognised physical phenomenon – 'The Bernoulli Principle' – named after the Swiss scientist Daniel Bernoulli, whereby a fluid's velocity must increase as it passes through a constriction to satisfy the conservation of mass, while its pressure must decrease to satisfy the conservation of energy.
Hydroventuri's technology uses this pressure drop to introduce gas into a liquid, particularly, but not exclusively, air into water. State of the art research and development methods have lead to a highly novel and robust design, centred around a 'venturi insert' into standard sized pipe-work, that enables the delivery of smaller bubbles with greater control and significantly less energy consumption than alternative aerators, but which can effectively pass and aerate very large volumes of flow. Thereafter the focus is on controlling the size of the bubbles that form, their shape and behaviour, in order to optimise oxygen transfer.
This provides new opportunities in terms of how the technology can be applied, at what scale, and with what external energy input. Indeed in many situations the technology can be operated with no external energy input at all, providing there is sufficient hydraulic head available.
At our Newport Test Facility (shown here) we now have a fully operational commercial scale demonstration unit which can be configured to simulate the particular needs of our clients.
A smaller “lab-scale” system is also available for testing the effectiveness of Hydroventuri’s HiMix™ aeration system on our clients’ specific liquids.
