• Incorporating SAF technology
• To serve 50-350 population equivalent
• Ideal for longterm or temporary / interim solution

BISON CONCRETE RANGE
50-350 P.E.
This range of treatment plant design incorporates submerged aerated SAF technology and is particularly suitable for mid-range applications for the treatment of domestic wastewater.

The system achieves a 20:30 BOD:SS standard for discharges and is designed for installation completely below ground.

Typical applications include all types of commercial, leisure, industrial and housing development projects where access to a main sewer is not an option.

THE PROCESS

• Combines all the treatment processing into a series of concrete tanks

• Choice of systems

• Standard for normal discharge consents of 20:30 BOD:SS

• Nitrification for tertiary treatment up to and including
10mg/l ammonia standard

• Designed to combine the conventional settlement stages (primary, secondary, humus) with submerged aerated filter (SAF) technology as the main biological process

• Incoming sewage is separated and stored in the primary and secondary settlement tanks, allowing only settled liquor to pass forward for biological treatment

• The biological treatment stage comprises of an aeration tank with submerged filter media and a diffused aeration system

• Biomass (humus sludge) sloughed from the submerged media is separated in the final humus
settlement stage and returned intermittently by pump to the primary stage for co-settlement
