CHIGI® is a system that overcomes the design and efficiency limits of conventional systems. What’s more, unlike conventional systems, CHIGI44® has a vast range of possible uses.  CHIGI44® is economical and boosts efficiency, flexibility and adaptability beyond all expectations.

 

CHIGI44® BREATHING WATER TECHNOLOGY

The exclusive ATI SRL CHIGI44® BREATHING WATER is a state-of-the-art technology in treatment and oxygenation solutions for any body of water.

Efficient, silent, resistant to pressure changes up to 6 bar and very versatile, it is suitable for a large number of applications:

  • tank and open-water fish farming
  • mussel farming
  • Civil and industrial wastewater treatment
  • vegetation water treatment
  • farm wastewater treatment
  • landfill leachate treatment
  • biomass production (algae growing in tanks and in the sea)
  • stabilising lubricoolants
  • flotation, mining, excavation, hydrocarbon pollution, oxygenating polluted aquifers

CHIGI44® technology is inherently ecological: it can be powered by both wind and solar energy, it has no impact on the environment and its quietness means it is well tolerated by fish in fish farms.

CHIGI44® is powered using just the evaporation energy of oxygen (able to reach pressures up to 6 bar), without the need for additional energy sources.

CHIGI44® represents a total paradigm shift from the mechanical technologies adopted so far, which are characterised by high installation and maintenance costs and high energy consumption, but low efficiency levels.

CHIGI44® COMPARED TO CONVENTIONAL SYSTEMS

Chigi44® is a system that revolutionises the biological oxidation plant sector, overcoming the design and efficiency limits of conventional systems. What’s more, unlike conventional systems, CHIGI44® has a vast range of possible uses.

With Chigi44®, you can make savings and boost efficiency, flexibility and adaptability beyond all expectations. Only an in-depth examination of the system’s characteristics and innovations compared to conventional plants can reveal the huge potential of CHIGI44®.

CHIGI44® technology generates microbubbles that produce an unrivalled oxygenation level thanks to a large contact surface and a very long ascent time.

CHIGI44® BREATHING WATER TECHNOLOGY CONVENTIONAL SYSTEMS
Streamlined, modular design, easily adapted to requirements. Rigid, non-expandable structures, anchored to the base.
High efficiency in any application. Low efficiency and poor operating flexibility.
Intrinsically environment-friendly technology. Can be powered by solar and/or wind energy. Operating rigidity and high energy costs.
The use of individual modules, which can be removed, allows maintenance to be performed without stopping the working cycle. Conventional systems are structurally rigid due to their anchors. Maintenance is complex: tanks have to be drained and working cycles interrupted.
Pressures may vary from 0 to 6-8 bar without affecting the structure of the microbubbles. Limited operating pressures, no flexibility in terms of power supply.
Excellent operating flexibility and oxygenation efficiency that improves as head increases. Low oxygen transfer to water due to the system’s technological limits.
The use of oxygen favours the production of high water heads (6-10 m). Conventional systems only function with low water heads.
One positive side-effect of the use of oxygen is odour elimination. Poor odour elimination capability.
In the design phase, CHIGI44® can be constructed vertically instead of horizontally, allowing variations in population equivalent to be managed with a single system in which the levels are adjustable and by simply regulating the oxygen. No flexibility, high operating costs even when underused. Conventional systems operate with low heads and therefore require vast areas and complex machinery with high energy consumption: costs are high even when plants are underused at specific times of year.
CHIGI44® configurations can be customised to user needs. Conventional systems do not allow customised configurations.
