Entex’s Octopus aeration system is a floating, surface-maintainable aeration system. This system offers the advantages of fine or coarse bubble diffusion and is based on the use of a stainless-steel float pod. Diffusors are installed on the bottom of each of the unit’s eight legs. The leg lengths are custom- manufactured to reach the lowest possible point in your basin to maximize bubble contact and subsequent oxygen transfer efficiency.
Air is supplied from blowers located on the shore, eliminating the need to maintain motors out in the water which is common for other systems. The manifold system is engineered to maintain a constant pressure throughout the system. Each Octopus is secured with stainless fittings to a mooring station.
Octopus system benefits
- Half the electric cost of splash surface aerators
- All stainless-steel construction for long service life
- High efficiency fine bubble diffusers
- Up to 32 fine bubble diffusers per Octopus
- Induces large airlift mixing cells
- Wet installation into existing basins
- System designed to be operational while single units are shut down for service
- Legs are individually removable, contributing to easy maintenance
- Ideal for lagoons, tanks, SBRs, extended aeration basins, activated sludge, aerobic digesters, and aquaculture
Easy maintenance
Diffusers are easily maintained. Simply shut off the air to the Octopus unit to be serviced, remove each leg as required via their quick disconnects, and service the diffusers. This process takes no more than five minutes per leg. You do not have to shut down the whole system to service an Octopus unit.
Addresses common concerns
Each unit sets up large mixing cells, eliminates aerosol concerns associated with high speed floating aerators and is well suited for cold weather operation and basin heat retention.
Oxygen transfer efficiency
Oxygen transfer efficiencies are determined by the size of the bubble and the depth of discharge. The Octopus system allows fine bubbles to be introduced at the lowest possible depth in the system, maximizing OTE.
Energy-saving technology
Our Octopus systems are an operator- and energy-friendly replacement for high speed floating aerators. With fine bubble diffusers, they take less than 1/2 the energy to provide the same aeration. This directly translates into significant energy and maintenance savings for customers, which provides a rapid payoff of capital and installation costs.
Cost-effective synergies
Octopus supplements Entex’s portfolio:
- For projects that require aeration along with Webitat, WavTex, or BioBloc, Entex offers a comprehensive solution of attached growth biology and supplemental aeration.
- Entex also provides offerings for lagoons and other basins that need aeration but not additional biomass.
- Octopus provides an effective solution for industrial facilities that require additional aeration but cannot shut down operations in order to modify floor mounted diffusers.
