We’re growing the legend of Algae,
in our patented, one-of-a-kind Algae Cultivation System.

Symbiotic’s Algae Cultivation system has undergone over 10 years of development and rigorous scientific pilot testing. Its been proven not only to be a highly efficient alternative to modern-day terrestrial crop farming, but also to be very effective at remediating agricultural, industrial and municipal wastewater streams and green house gas emissions.

Mac-B™ System

The system utilizes wastewater, waste heat, CO2 and other waste streams emitted from present day industrial and agricultural processes as inputs, towards the goal of achieving a net neutral carbon demand. It’s a system of easily deployable photobioreactor modules, that utilize both solar and artificial light, a one-of-a-kind media agitation system and a gas mixing and delivery system for delivering specially formulated nutrients, developed specifically for the Mac-B™ system to most effectively accelerate algal growth.

The Mac-B™ system overcomes the limitations of first generation photobioreactor technologies, unlocking the ability to co-locate algae cultivation activities, in extremely hot, moderate or cold climates, in close proximity to waste emitters regardless of their geographic local. The system effectively enables utilization and “monetization” of non-productive waste in the process of growing algal biomass. It takes advantage of the incredible ability of microalgae to quickly metabolize non-productive waste streams, transforming them into renewable biomass that in-turn is used in the production of multiple output products.

The bioreactor modules are insulated and combine natural and artificial light to maximize algae production 24/7. They are portable and scalable by multiples of two, making it possible to size the biofield™ to match available wastewater and CO2 waste streams.

Scalability

Scaling is achieved by simply adding the inter-connectable bioreactor modules. The Mac-B™ system consist of up to eight commercial scale (106,000 liters, 106m3) (28,000 gallon), or (26,000 liters, 26m3) (6,868 gallon) left-and-right modular components, that are coupled together and linked end-to-end to form production cells. Each module is engineered to minimize water loss due to evaporation and when coupled together, they provide significant wet growth media capacity in a relatively small footprint.

One production cell has a wet growth media capacity of 848,000 liters. Eight production cells are configured to form a commercial cultivation biofield™, that fits easily on a two-acre lot with more than adequate room for laneways through and around the biofield™. The 64 module biofield™ configuration has a wet growing capacity of 6,784,000 liters. The production cells are automatically controlled by a Head Control Unit (HCU) which houses the nutrient feed, Water-Gas-Mixing system, circulation pump and process controls. 

Deployment

A flat, solid foundation with grade beams is all that is required to support the portable bioreactor modules. No permanent structures, or extensive ground work. Modules can be delivered by truck and spotted near the waste source, on minimal space. For permanent applications the modules can be assembled or built into permanent structures.

Submersible Lighting

Each module is equipped with submersible LED lighting, designed exclusively for use with the Mac-B™ system. The LED’s operational, spectral and irradiance profile are tailored to optimize photosynthetic saturation levels throughout the reactor trough so to effectively accelerate cell growth. The spectrum, intensity and duty cycle are programmable and can be programmed to accommodate the different growth characteristics of different algae strains. The submersible fixtures can be configured so that a percentage of heat load given off by the light elements are unloaded directly into the growth media. 

Mixing

The Mac-B™ system uses an innovative approach for agitating the growth media. The design incorporates a unique mechanical propulsion system to physically stir up and move the large volume of growth media without sheer damage to the growing algae cells, while ensuring equal distribution of nutrients and even exposure to light.

De-fouling

The modules are large enough to allow easy access to the inside of the reactor trough for de-fouling and general cleaning.

Growth Environment

The outer hull and the reactor trough are fully enclosed to reduce contamination risks from the outside, while maintaining an un-corruptible, internal growth environment at ideal thermal levels (heating and cooling) for optimally supporting algae growth. The modules can be configured so that the reactor troughs are isolated from each other to reduce the risk of cross contamination from within, or to limit propagation in the event of catastrophic internal bacterial infection. Each module can also selectively be taken offline for routine maintenance without shutting down the other modules in the biofield™.

Versatility

The system is ideal where space is limited. The modules can be assembled in a multiple of outdoor biofield™ configurations. In applications where assembling the biofield™ inside a building makes good economic sense, the outer weather protection hull can be eliminated so that the bioreactor troughs can be stacked on a suitable substructure, inside the building.

Durability

The Mac-B™ system is designed for overall sustainable performance. It is a commercially scalable, industrially robust system, made of cement, stainless steel and polycarbonate materials for maximum operational usage and long service life.
