Graphic illustration of Industrial and Agricultural processes where the Mac-B™ system can be deployed:
The bioreactor modules are insulated and combines 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 cultivation biofield™ to match available wastewater and CO2 waste streams, emanating from any agricultural or industrial industries, anywhere, in any climate.
Scaling is achieved by simply adding or subtracting the inter-connectable bioreactor modules. The Mac-B™ system consist of eight commercial scale (106,000 liters) (28,000 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 modules biofield™ configuration (see 3D graphic illustration below) has a wet growing capacity of 6,784,000 liters. The production cells are controlled by a common Head Control Unit (HCU) which houses the nutrient feed, Water-Gas-Mixing system, circulation pump and Process Logic Controls. One HCU controls one production cell.

A flat, solid foundation is all that is required to support the bioreactor modules. No permanent structures, footings or extensive ground work are required. Modules can be delivered by truck and spotted near the waste source, on minimal space.
Each module is equipped with supplemental, 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. Water cooled versions allow the head load to be removed and utilized in other areas of the process. The fixtures are available in either a flat panel or tube design.
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.
The modules are large enough to allow easy access to the inside of the reactor trough for de-fouling and general cleaning.
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™.
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.
The Mac-B™ system is designed for overall sustainable performance. It is a commercially scalable, industrially robust system, made of steel and durable polycarbonate materials for maximum operational usage and long service life.
