HOA Series · Oxygen Dissolution System

Oxygen Dissolution System HOA

HOA is an oxygen dissolution system that raises dissolved oxygen in stored water using a submersible pump and oxygen dissolving unit. It suits sites where oxygen supply is the goal, such as irrigation tanks, aquaculture tanks, ponds and reservoirs.

Benefits of an oxygen dissolution system

A configuration designed to dissolve oxygen in water and raise dissolved oxygen in irrigation, aquaculture and water bodies. Technical characteristics and conditions for each process are covered on the application pages.

Applications for HOA

Suited to applications that aim to raise dissolved oxygen efficiently.

When HOA is a good fit

  • Sites where raising dissolved oxygen is the goal
  • When the unit is to run inside a tank, reservoir or water body
  • Farms that want to keep existing irrigation piping unchanged
  • When the required flow matches one of the 3 standard models

When another series fits better

  • For aquaculture farms and water bodies with large volumes and long operating hours, HEN
  • For high dissolution efficiency or ozone, HQN
  • For strict hygiene standards, HTV

Concept diagram of the submersible pump type. Actual layout and gas supply method depend on site conditions. HOA-010 and HOA-020 can be configured with a centrifugal pump instead of a submersible pump.
  1. Submerged installation

    The unit is placed under water in the irrigation tank, reservoir or water body.

  2. Oxygen dissolution

    The submersible pump draws in water and dissolves oxygen.

  3. Circulation

    The oxygenated water circulates within the tank or water body, raising dissolved oxygen.

Sites requiring more than 20 m³/h use multiple units in parallel.

HOA FAQ

Answers to key technical and adoption questions when considering HOA.

How does HOA differ from a nanobubble system?

It is an oxygen dissolution system designed specifically to raise dissolved oxygen.

For processes that need high dissolution efficiency or high-density nanobubbles we recommend HQN, and for high flows HEN. Tell us your purpose and water volume, and we will review the right product.

Do I need to replace my existing irrigation equipment?

Existing piping is kept.

The unit is placed inside the tank or reservoir to circulate the water. The oxygenated water is delivered through the existing irrigation pump and piping.

What if there is not enough room to place it in the tank?

A configuration running on a surface pump is considered.

HOA-010 and HOA-020 can be configured with a centrifugal pump. HEN, which runs on a standard surface pump, is also considered.

Which gases does it use?

It uses air, O₂ and N₂.

Oxygen is used to raise dissolved oxygen. Gas supply equipment is reviewed together to suit the application and model.

Can it be used in large ponds or reservoirs?

Configuring multiple units in parallel is considered.

The number of units and layout depend on surface area, depth and power conditions. For large waters with long operating hours, HEN is also considered.
