Photobioreactors

Every aspect of Industrial Plankton's photobioreactors can be adjusted to provide ideal growth parameters for practically any species of algae. This allows our systems to be incredibly productive and dependable. Our photobioreactors eliminate nearly all of the repetitive and time consuming aspects of algae culturing, allowing operators to focus on the rest of their production.

CLEANING & STERILIZING

Industrial Plankton's tanks are designed with biosecurity in mind, using triclamp plumbing, autoclavable tubing, a crevice free tank design, and a simple to use, built in spray cleaning system. Cleaning is done in several stages, first a detergent spray cycle is used to remove biofilms, then a bleach spray cycle is used to sterilize the tank, and finally thiosulphate is added to neutralize any residual bleach before draining the tank and prepping for inoculation.

CLOSED LOOP pH CONTROL

Our pH control system measures the reactor's pH using a pH probe and opens a CO2 solenoid anytime the pH rises above the operator's set point. The pH set point can be changed at any time using the touchscreen.

INOCULATION

The photobioreactor starts by adding water, which is filtered and UV sterilized as it enters the bioreactor. Then nutrients are automatically added, and the temperature and light levels are adjusted. Inoculation is simple, just hook up a carboy or flask to the machine's inoculation port, then use the onboard air supply to push the culture from the carboy into the bioreactor without ever coming in contact with the outside world.

HARVEST

The PBRs can be run in batch or continuous mode, and can be harvested from at any time by inputting the volume to harvest on the touchscreen. In batch mode you decide when it's dense enough to harvest. In continuous mode, the PBR harvests your set volume each time it reaches your set density. Then new water, and nutrients are automatically added to replace the harvested volume, allowing this cycle to continue automatically for months.

DENSITY SENSOR

Our proprietary density sensor allows the control system to grow algae without operator babysitting. Our photobioreactors automatically increase light levels, add culture media, and harvest based on operator controlled set points to allow for continuous exponential algae growth.

LIGHT

Light quality is paramount for optimal algal growth. We ensure the lighting on all our reactors matches a broad photoactive spectrum for optimal algae growth.

Spectral customization is available for clients with specific requirements outside of pure biomass production, allowing the spectrum to be tailored to improve lipid percentage, carotenoid production, etc.

AGITATION

Our custom bubble distribution system allows for maximal gas exchange and water motion, while being gentle enough to avoid cell damage from shear stress. A bubble column is used for circulation, moving the algae between brightly lit and cell shaded areas at a rate that ensures the cells have sufficient light for growth.

USER INTERFACE

The touchscreen controls give operators complete control over critical parameters. In real-time, the software logs and graphs the culture and allows the user to fine tune and maximize their algae growth.

Though the reactor is automated, operators can also manually control it, making harvesting, scale up or anything else simple and fast.

TEMPERATURE

Each reactor has closed loop temperature control, and uses a custom heat exchanger and chiller/heater to maintain your desired culture temperature. This provides the freedom to grow temperate, tropical or even some polar species in our PBRs.

TANK DESIGN

Our patented tank designs significantly increase the volume that is sufficiently lit, which allows cultures to grow denser before self shading hinders growth.
