06 / MICROALGAE CULTIVATION
A biological approach to
carbon and nutrient streams.
Microalgae solutions that bring culture selection, cultivation, harvesting and resource integration into a single project.

Microalgae Systems
Designed around the resource.
Scoped around the objective.
Microalgae cultivation requires coordinated control of species, water quality, light, temperature and nutrient balance. System design starts with the target biomass and its intended use.

THE PROCESS
How does the system work?
01
Species & objective
Selecting a culture suited to the intended biomass use and cultivation conditions.
02
Cultivation
Controlling light, temperature and nutrients in a photobioreactor or suitable open system.
03
Harvesting & concentration
Separation and dewatering suited to species and product requirements.
04
Product & recirculation
Preparing biomass for its target use and recovering suitable water and nutrient streams.
SYSTEM SCOPE
Engineering components
considered together.
Equipment and process options are selected according to project inputs and target outputs.
CO₂ & nutrient preparation
Quality control of gas and liquid streams; dosing and feeding suited to the culture.
Monitoring & control
Monitoring pH, temperature, light conditions and culture development.
Harvesting line
Filtration, centrifugation or another suitable concentration method according to biomass characteristics.
THE STARTING POINT FOR DESIGN
What data does your project need?
| Target product | Species, biomass characteristics and intended use |
|---|---|
| Water & nutrients | Water quality, nitrogen/phosphorus source and inhibitors |
| CO₂ source | Composition, purity, flow rate and gas preparation requirements |
| Site & scale | Light, climate, space and pilot trial results |
Commercial scale is determined through culture trials, harvesting assessment and product evaluation.
FREQUENTLY ASKED QUESTIONS
Key points before making a decision.
Can digestate supply nutrients for microalgae?
After suitable pretreatment, dilution and analysis, it may be considered for some cultures. Ammonia, salinity, light transmission and contamination risks are assessed in pilot trials.
Can the biomass be used as food or feed?
Suitability is not automatic. Species, feed source, purity, product safety and the requirements of the intended use are decisive.
