Maple Leaf
Maple Leaf's pig slaughterhouse in Brandon, Manitoba, Canada is one of the largest in the world and the most modern in North America, with a capacity of 9000 pigs per shift.
It generates 680 m3/hour (3.000 GPM) of waste water. This has to be purified to comply with environmental requirements.
The system supplied by MPS AQUA uses no chemicals and can decrease the oil and fat concentration to 80 mg/l.
The pre treatment removes floating particles and fats from the water with external rotating filters and MPS AQUA's advanced DAFINCI DAF units.
The DAF sludge is dewatered by a decanter centrifuge to minimise operating costs and sludge transport. (The sludge is processed in a rendering factory in Winnipeg, 200 km from Brandon (125 mi).
Although this system processes an enormous effluent stream, it needs a minimum of supervision.
Maple Leaf chose to integrate a smart way of saving on labour costs in their waste water treatment:
- AQUA's variable speed - separately feed rotating filters. These filters are almost maintenance free when the intermittent internal spray system has been activated.
- AQUA's DAFINCI DAF units are equipped with an automatic auger sediment disposal system, that prevents dehydration of the DAF unit for the sediment removal, a task that can last many hours.
- AQUA's sediment separators gather and dehydrate the muddy water that is discharged from the sediment pipes of the DAF units automatically. Without the MPS sediment separator an operator could spend hours on the digging out of sediment material.
- All waste discharge equipment has been placed on the second floor, exactly above the trailers, so it takes away labour for internal handling.
Maple Leaf proves, that high capacity systems not necessarily have to be labour intensive systems.
