WATER REMEDIATION

Chemical free and high oxygen transfer rate treatment

Maintain adequate dissolved oxygen (DO) levels in small and large water bodies.

Control algal blooms caused by Low DO levels combining with excess nitrogen and phosphorus in the water.

Bubble neutral buoyancy enabling sustained DO levels through the water column (Epilimnion, Metalimnion and Hypolimnion)

Improve water clarity and turbidity

Passive sediment oxygenation

Reduce odours and fish deaths

Government Fisheries Dissolved Oxygen Trials

The Custom Fluids system produces trillions of neutrally buoyant, negatively charged Ultrafine Bubbles (nano-bubbles) that are 100nm or smaller in diameter.
These properties the bubbles stay suspended in water for long periods of time, efficiently mixing throughout the entire body of water and transferring oxygen at least 85% efficiency.
As the bubbles burst over time, Oxygen is made available and transferred to the water. The bubbles transfer oxygen at any depth and survive in solution for weeks, even in warm temperatures.
The system is an energy efficient, chemical free and environmentally friendly solution to raise Dissolved Oxygen levels in water bodies.

The trial

Custom Fluids recently carried out a Water Oxygenation trial at a Government Fisheries in Australia.
The trial involved 2 ponds, both approximately 100m x 15m x 1.6m equating to approximately 2.4 Mega-litres. The first pond (right pond in image) was the Oxygenated trial whilst the other (left pond in image) was a control pond with a conventional and commonly used aeration system that mixes air (not Oxygen) and water.

The Custom Fluids system was installed in the open near the trial pond and required only two 240 Volts sources to operate. The system worked with a fixed flow rate of approximately 350 litres per minute drawing water from the trial pond itself.

The results below show Dissolved Oxygen levels over the 21 days the trial was carried out. The data points are plotted in four sections covering the days the dissolved Oxygen were measured. Each section has 10 data points representing each 10 metres distance from the source of Oxygenation.

Key Facts and Benefits

Client: Government Fisheries
Pond Dimension: Approx. 100m x 15m x 1.6m
Pond Volume: Approx. 2.4 Mega-litres
Application: Raise Dissolved Oxygen Levels
System Flowrate: 350 LPM

Key Benefits:
  • Peak Dissolved Oxygen level in the trial pond reached 153% at day 15 whilst the control achieved 118% in the same time.
  • Within 46 hours, Dissolved Oxygen levels exceeded the control pond by 20%
  • MaximumDissolved Oxygen levels reached 45% reached 10m from source
  • Peak Dissolved Oxygen levels across the entire pond 30% above the control pond
  • Total Gas Pressure (TGP) remained consistent with the control pond throughout the trial and remained well within US EPA levels.
  • At the furthest distance (100m) from the Oxygenation source, 22% above the control pond was achieved.
  • After both systems were powered down, the trial pond remained 30% above (average) the control pond

Client remark: “The impact of the aerator across the entire pond is very evident….. The minimum readings of the aerated ponds in most cases exceed the maximum readings in the control pond.”
