Philadelphia Zoo
Bear Country Filtration
Location: Philadelphia, Pennsylvania
Area: 120,000 gallons
Construction Cost: $403,000
Major Project Spaces:
• Freshwater polar bear pool
• Improvements to existing exhibit

The Philadelphia Zoo sought out an experienced life support engineering team to address the filtration and algae problems they
were experiencing in their polar bear pool. Alvine Engineering's team was selected to design the life support,
mechanical and electrical systems modifications. Improvements were made to the exhibit to reduce water stagnation, disinfect the
exhibit on a continual basis and replace aging equipment with more efficient and economical equipment.
