Inlet with ‘Forsheda seal’ Forsheda seal provides flexibility in the joint for easier installation. Optional risers to increase invert depth are available.
Primary settlement chamber
Aeration chamber
Advanced compressor with alarm (Ensign:Ultra units only) Near silent compressor ensures minimal running, maintenance and servicing costs. Integral alarm detects low pressure in air line. (Regular Low-energy compressor on Ensign:Standard models).
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.
RCD/Electrical connection (Ensign:Ultra units only) The RCD box provides easier installation and provides a higher degree of safety. (Regular plug/socket connection on Ensign:Standard models).
PVC pressure pipe/diffuser(s) Provides a protective conduit for the air diffuser line. Can be easily removed for maintenance and cleaning.
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 stainless steel securing mesh to ensure no migration during handling or potential flooding.
Stainless steel mesh Retains media in aeration chamber during transportation and handling, and in the event of flooding.
Final settlement chamber
32mm sludge return 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.
Unique Polylok tertiary filter (Ensign:Ultra units only) The Polylok tertiary filter reduces suspended solids and BOD by a further 40% helping to extend drainage field life.
Outlet with ‘Forsheda seal’ Forsheda seal provides flexibility in the joint for easier installation. Optional pumped outlets are available.
Impermeable lid Heavy duty lid/frame improves strength and durability whilst blending into the surrounding environment. (Regular lid on Ensign:Standard models).
Integral lifting eyes For safe and secure on-site handling.
Stabilising feet Stabilising feet prevents the tank from rolling and allows safe and steady transportation and installation.
Unique ‘keying-in’ lip Assists anchoring into granular or concrete surrounds.
