Project Background

Tucked away in a hidden enclave on Sydney’s North Shore is a private golf course. The golf course was crafted in 1926. The golf club is certified as an Audubon Society Cooperative Sanctuary for outstanding environmental management, and it harbours abundant birdlife. The course green keeping and management use cutting-edge water management systems [such as nanobubble technologies] and conducts their affairs in an environmentally friendly and reputable way.

The Problem – low dissolved oxygen [DO] and destratification

The golf course did however have a water issue they needed to tackle. A long narrow dam of theirs in the base of a gorge, suffered from low dissolved oxygen [DO] and destratification. The low DO causing unwanted odours and poor water quality for use on the course.

“The results look fantastic!”

– Managing Director of the Consultancy Firm

The Options

A consultancy firm contacted Hydro Innovations on behalf of the golf course and inquired about a Venturi Aerator.

How do Venturi Aerators work?

They require a pump to deliver flow to the inlet nozzle [under pressure], where an increase in velocity uses the Venturi principle to draw in atmospheric air, mix it with the water, and discharge it saturated with DO into the water. Venturi-Aerators are very efficient at delivering DO, but because the suction and discharge of the system can be located at any depth within the water, destratification issues could also be dealt with.

The Solution

Two pumps were installed in the system to deliver flow to two 4″ Venturi-Aerators, which were set up to deliver 11.8kg of DO per hour per unit.

The results? …. They were great!

After running the units for a few weeks, Oxidation Reduction Potential [ORP] and DO readings were taken. The ORP went from -125mV at a 3m depth to + 130mV. The DO levels increased from less than 0.3mg/L to 6.0mg/L and 7.3mg/L at a depth of 4.75m.

The Managing Director of the consultancy firm said, ” the results look fantastic!”

Hydro Innovations will generally pair Venturi-Aerators up with Gorman-Rupp self-priming pumps to allow installation of the  systems on the banks of lagoons, making them safer and more cost-effective to maintain. When the right pumps are selected, oxygen transfer rates can be as high as 1.86kg O2/kWh, making good use of available power.

The Products

The Venturi Aerator features a classic design for modern applications. Whether you need a complete replacement or simply an enhancement to your existing system or lagoon, the Venturi Aerator offers an innovative and convenient approach to your aeration needs.

The EchoStorm water aerator from Gorman-Rupp offers the benefits of safety, reliability and ease of access to water aeration applications.

Because these units are mounted on the bank [instead of floating on the water or being submerged in it], access is much less complicated and safer, while delivering oxygen transfer outcomes.

The EchoStorm water aerator benefits::

  • No cranes or row boats for maintenance
  • Easily accessed
  • Less downtime
  • Reliable and easy to maintain
  • Easily scalable and low cost of ownership
  • Thorough mixing – no dead spots
  • High SOTR (Standard Oxygen Transfer rate)
  • Oxygenated water

These aeration units are used in conjunction with Gorman Rupp self-priming centrifugal pumps to deliver solutions for the following applications:

  • Lagoon and basin water aerator
  • Oxidation ditch aeration
  • Lake destratification and algae control
  • Odour control
  • Sludge digestion
  • Septage treatment
