Full Description


• Tested to BSEN12566:3 and CE-marked to ensure compliance with latest environmental and Building Regulations requirements
• Class-leading effluent quality of 11.5:19.2:8.4 (BOD:SS:NH4 ) ensures discharges well within national consent standards
• Three chamber system correctly sized for separation and retention of solids improves final effluent quality
• Standard or shallow options enable suitability for all site conditions (including driveways - subject to plinth/surround to prevent superimposed loadings)

• Low energy compressors ensure minimal running, maintenance and servicing costs
•High specification bio-media (310m3 per m2 ) and membrane diffusers ensure even circulation to eliminate 'dead spots'
• Internal recirculation (from final to primary chamber) continues treatment process to provide higher effluent quality whilst balancing flow over 24 hour period or periods of intermittent use
• Integral lifting eyes for improved on-site handling
• Unique 'keying-in ' lip to assist anchoring into granular or concrete surround
• Optional extras include patented Polylok filter to further reduce suspended solids and extend life of drainage field; extensions for deep installations; pumped outlets for sites with adverse levels; and many more
