THE EVOLUTION OF ALGAE GROWING SYSTEMS
Stages in the photo bioreactor development process
Algae has been growing on the earth since the beginning of time. It grows where ever there is water, light and nutrients. The designs for devices or systems to grow algae are based on these factors.
The 1st Generation of algae production systems utilized designs based on still ponds, pivot ponds and a variety of designs of tanks. These first generation systems were crude and had all of the drawbacks and problems associated with growing algae in the open.
The next generation of algae growing systems, the 2nd Generation, attempted to overcome some of the more obvious problems associated with the 1st generation systems. They utilized raceway ponds which allowed for “paddle wheels” to be applied that served to circulate the contents of the pond. This allowed for the better distribution of the nutrients that were added to the water, but that was about all they accomplished.
Raceway Pond systems
The 3rd Generation algae growing systems attempted to overcome some of the problems with the provious systems. Verticle or slanted clear pipes and hanging bags were used to allow for the controlled circulation of the water and the mixing of the nutrients, plus the introduction of the CO2 which is a necessary component of the feeding process for the algae. These systems were an improvement on the first two system designs but still only addressed a small number of the problems associated with algae growing.
The 4th Generation systems saw the introduction of horizontal, closed, full flood tubes connected together to form a photobioreactor. These systems had a significant advantage in that they could limit the contaminates that could entere into the algae being cultured. The also had all of the advantages of the first three systems, in that there was controlled circulation in a continuous racetrack configuration, with some allowance for the injection of nutrients and CO2.
Closed Photo Bioreactors
5th GenerationAPS has developed a 5th Generation algae growing system that incorporates a closed, non-full flood photobioreactor that employes computer controls to regulate such things as flow rate, feeding, and the offtake of harmful O2 that is released in the process of the algae growing.
APS Photo Bioreactors
The main factors that any algae growing system must address in order to successfully maximize the growth of the algae are as follows:
The APS 5th generation system is the result of several years of development, design and experimentation. Given our extensive research into, not only the science of algae, but also the mechanical components of a successful system design, the We feel that there is no other system on the market today that can match the APS system.
