Tiivistelmä
The possibility of using algae to clean wastewater has recently gotten attention because wastewater is becoming a bigger problem all over the world. Many scientist and engi-neers are researching better ways to utilize the high potential of algae to clean these waters. By experimenting with algae we try to explore the potential of growing algae on a mechanical system called “algae turf scrubber” or “ATS” to absorb the excess nutrients for the production of biomass.
By knowing the amount of nutrients added we could see the results in the absorption productivity of our inoculated algae in the ATS. We also wanted to see the influence light and pH would have on the growing potential of the algae. The relationship be-tween pH and total nitrogen were investigated while observing the influence of light.
In conclusion it was determined that if conditions are optimized the system would be well suited in Finland. The ATS could also be used in addition to conventional wastewater cleaning systems.
