Glossary
Heterotrophic
Refers to obtaining nourishment from the ingestion and breakdown of organic matter such as plants and animals.
Glossary
Growth rate
The speed that the number of organisms in a population increase per unit time. In our PBRs we look at the culture inside as a population.
Glossary
Feeding rates
Generally refers to the speed, or a ratio, that animals are given nutrients. For example larval shellfish require a certain number of algal cells per day to thrive, though this value may also be given as an algal density suspended in a flowrate, or it could be as a volume of dense algae given several times a day.
Glossary
Exponential growth phase or logarithmic growth phase
The period of growth during which the algae population grows at an exponential rate.
Glossary
Diatom
A group of mostly photosynthetic single-celled algae, that form silica cell walls. They can grow singly, in chains or in simple colonies, both suspended in the water column or on the benthos (surfaces).
Glossary
Control system
The brains of our PBRs. Where you’re able to see use the HMI and touch screen to control pH, temperature, nutrient addition, harvest volumes, etc. Note, the control system can also be accessed through Wi-Fi, so you can control from another web enabled device.
Glossary
True Continuous culture
A state where water and nutrients are constantly entering the PBR, diluting the algae, and this incoming water forces water rich with algae out the overflow.
Glossary
Cleaning Cycle
The reactor is equipped with rotary spray balls and a spray pump to wash the tank internally between culture runs. Cleaning and sterilizing between culture runs in a 2 step process: biofilm removal and chlorine sterilization. Downtime and manual labour areis very minimal for cleaning our PBRs. Though the cleaning cycle takes 2-4 hours, you let the spray system work for you, like a dishwasher.
