Large-Scale Algae Culture Service

Algae can produce renewable fuel sources, nutrients such as proteins and lipids, a variety of chemicals and bioactive substances, and can also be used for the resourceful use of wastewater.

To complete the large-scale culture of microalgae, we need to purify the microalgae, select the culture method of microalgae, and design a suitable photobioreactor. Lifeasible can offer professional large-scale algae culture services to facilitate your industrial production.

Overview of Photobioreactor

A photobioreactor (PBR) is a culture system designed to promote the growth of photoautotrophic organisms using artificial light or solar energy. PRBs are divided into two classes. One is the open systems, while the other is the closed PBRs.

Open PBRs

Open PBRs, such as raceway ponds, natural ponds, artificial ponds, and circulation ponds with stirring devices, rely on natural light and sources of carbon dioxide completely. Although open PBRs are cheaper and easier to build and operate than closed PBRs, there is always a risk of contamination.

Closed PBRs

Closed PBRs can be classified as stirred tanks, vertical tubular PBRs, horizontal tubular PBRs, and flat-panel PBRs. Ideal PBRs should have a highly transparent surface, minimal non-lighted fraction, high mass transfer rate, and should achieve high biomass growth.

• Closed Stirred Tanks
  Closed stirred tanks are conventional aerated bioreactors in which mixing is achieved by mechanical agitation. The core component of a closed stirred tank bioreactor is the stirrer and impeller. Carbon dioxide-rich air bubbles at the bottom, providing a carbon source for algae growth.

• Vertical Tubular PBRs
  The culture in vertical tubular PBRs is circulated with an air pump or air-lift system. Depending on the pattern of liquid flow, vertical tubular PBRs can be further divided into bubbling columns and airlift reactors.
• Horizontal Tubular PBRs
  Horizontal tubular PBRs consist of tubes with a variety of possible orientations such as horizontal, inclined, spiral, helical, and its variations, but all orientations work in essentially the same way.

• Flat-Panel PBRs
  Flat-panel PBRs consist of a frame with transparent plates covering both sides and a pump used to circulate the algal cell suspension. The main features are the high surface-to-volume ratio and the functional bubbling air from the bottom of each channel.
