1 Inlet
Optional risers to increase invert depth are available.

2 Primary settlement chamber

3 Aeration chamber

4 Low-energy compressor
Near silent compressor ensures minimal running, maintenance and servicing costs.

5 Compressor housing – internal or external options available
The compressor can be housed internally or externally with no difference in cost.
External recommended to increase compressor life, and supplied as standard on 4PE, shallow and pumped outlet versions.

6 PVC pressure pipe/diffuser(s)

7 Securing mesh
Retains media in aeration chamber during transportation and handling, and in the event of flooding.

8 Final settlement chamber

9 Sludge return (32mm)
Larger diameter sludge return prevents the possibility of blockages and improves system circulation. Provides higher effluent quality whilst balancing flow over a 24 hour period or periods of intermittent use.

10 Outlet
Optional pumped outlets are available.

11 Standard impermeable lid
Impermeable lid improves strength and durability whilst blending into the surrounding environment.

12 Stabilising feet
Stabilising feet prevents the tank from rolling and allows safe and steady transportation and installation.

13 Unique ‘keying-in’ lip
Assists anchoring into granular or concrete surrounds.

Bio-media
High specification bio-media (310m3 per m2) and membrane diffusers ensure even circulation to eliminate ‘dead spots’. The bio-media is contained by a securing mesh to ensure no migration during handling or potential flooding.

Integral lifting eyes
For safe and secure handling onsite.
