Piping for Penguins
Transcript of Piping for Penguins
Understanding the Filtration Process
1. Water is pumped into the main system
2. Sand filters
3. Ozone filters
4. Charcoal filters
5. Bubble removal tower
6. Water chiller
Scope and Limitations
What we excluded:
Certain aspects of the main system
Alternative housing for the penguins during construction
Zoo keeper access
Piping for Penguins will provide an emergency backup system.
60,000 gallons of recycled fluids cycle hourly
Staff on call 24 hours
No current bypass system
Automated system stops if there are problems
Piping for Penguins
Scope and Limitations
Ozone and Carbon Filters
Skid Mounted Membrane Filtration System
Membrane vs. Granular Filtration
An alternate water preparation system for the penguins at the Calgary Zoo
- Health and sanitation
- Water flow
- Conform to space constraints
To be used in the event of an emergency
What we considered:
Amount of water to be processed
Something different and interesting
Not directly related to oil and gas
The Calgary Zoo Penguin Plunge exhibit would greatly benefit from a secondary water filtration system. A skid-mounted water filtration system would be the best solution given the space and energy constraints.
A secondary system would be beneficial for the Calgary Zoo Penguin Plunge
The secondary system should be simplified in comparison to the main system, and focused
on maintaining water movement and cleanliness
The secondary system should be manually run as opposed to the automated main system
Retain pump and pipe sizing where possible for ease of maintenance and repair
Use of filter membranes in place of sand filtration to work within size and volume constraints
ENGD305, ENGD378, & PROJ357

The Piping Guide
Including a water chiller is not necessary due to the concrete construction of the building, and the short amount of time the bypass system will be implemented for
Due to the intended short term use
of the secondary system, adding in ozone and charcoal filters is not beneficial, and could be potentially harmful
What is included:
Membrane filter, c/w 6 filter cartridges
Skid-mounted water filtration secondary system
Limited time the secondary system will run
Reduced components decreases probability of issues

We've come to the tail end of Piping for Penguins.
The current process at the Calgary Zoo Penguin Plunge:
Particles are physically strained from the water
No coagulation, flocculation, and sedimentation facilities required 
Reduced chemical storage, handling, and residual-handling facilities
Allows membrane plants to be more compact and automated 
Membrane Filtration vs. Granular Filtration
Filtered water turbidity from membrane filters is independent of the concentration of particulate matter in the feed .
Membrane Filtration vs. Granular Filtration...
Rapid granular filtration is sensitive to fluctuations in raw-water quality and the experience of the plant operators.
