Klargester BioDisc® BA, BA-X, BB and BC (1 to 4 properties)*

For Domestic Dwellings without mains drainage, the Bio Disc from Klargester provides a reliable, efficient and environmentally safe solution to your sewage disposal needs. Its ideal for locations where discharge is to sub-surface irrigation, or to a suitable watercourse where approved by the Environment Agency, or appropriate regulating Body and where a septic tank will not meet the required standard.

• The Bio Disc is robustly constructed from corrosion free materials which help ensure the long life of the system.
• All treatment plants supplied by Owls Hall meet the July 2008 European Standard EN 12566 - Part 3 - Annexe B performance test regulations. The Bio Disc has achieved up to (95%) efficiency under varying loads and conditions through stringent testing procedures.
• It is the only treatment plant using the advanced Rotating Biological Contractor technology for small domestic homes. The Biodisc uses rotating discs as a medium for supporting bacteria which carry out the aerobic treatment process. Primary and final settlement are contained within the unit which also has a totally unique flow management system to provide optimum performance under all circumstances.
• The Bio Disc has the lowest running and maintenance cost of all treatment plants in its class.
• Manufactured under the quality procedures of BS ISO9001: 2000
• Low Running costs combined with the quality and durability of the equipment all add up to significantly lower life time costs.
• Owls Hall offer a full commissioning and after sales service involving planned maintenance visits. Please visit our servicing section for more information.

• The Bio Disc ensures optimum performance by smoothing peak flows and buffering biological loads through out the whole day.
• Access for service and maintenance is provided via a durable, unobtrusive cover at ground level.
• Three standard drain invert level options are available from stock to match the site topography and where applicable, minimise the excavation depth which helps decrease the cost of installation.
• BA, BA-X and BB Bio Disc’s are available with an integral pump to move effluent from point of treatment if site level demands.
