Research theme:
Wastewater treatment and resource recovery for plants and buildings
Purify wastewater and take up CO₂ in algal biomass, aiming to decarbonize and lower treatment cost
Bloomo purifies the ammonia and nitrate in wastewater from plants, facilities and buildings, and we are studying converting the harvested algal biomass into biochar for long-term carbon storage. The net reduction will be assessed by LCA. This research theme aims to combine wastewater treatment with decarbonisation and is currently at the research and suitability assessment stage.
Context, product, future
Context
Demand for decarbonisation is rising across facilities and plants, and a carbon tax may follow. Operators need to cut the cost of water treatment while also reducing emissions.
Product
Bloomo purifies the ammonia and nitrate in plant wastewater, and we are studying using the algal biomass for carbon storage as biochar and similar routes. How the carbon could be shown as credits or other environmental value is under study.
Future
Using Bloomo for water purification and decarbonization aims to lower the operator’s treatment cost. Using waste heat and flue gas is also being studied. We are working on calculation methods so that the carbon could one day be shown as carbon credits or other environmental value.
Users and product
USER
Plants, facilities and buildings
- High water treatment cost
- Meeting decarbonisation requirements
- Preparing for a carbon tax
- Responding to tighter effluent regulation
PRODUCT
Bloomo - Factory
Water purification and CO₂ uptake for plants and buildings (research stage)
- Water purification by algae
- Carbon storage as biochar (under study)
- Simultaneous removal of ammonia and nitrate
- Use of waste heat and flue gas
Core technology and features
Wastewater purification
Ammonia and nitrate taken up (assimilated) by the algae; organics are removed mainly by the bacteria living alongside them
Biochar production
Pyrolysing harvested algal biomass into biochar for long-term carbon storage (under study)
Use of waste heat
Plant waste heat used for temperature control of the culture, saving energy
Data visualisation
CO₂ uptake and water-quality data shown on a dashboard (net reduction assessed by LCA)
Resource recovery at sewage treatment plants
A research theme on an algae-based process improvement designed to fit into existing sewage treatment plants. It works on four layers (lower aeration energy, CO₂ uptake, nitrogen/phosphorus recovery and N₂O suppression), aiming to bring treatment closer to resource recovery (research and small-scale validation stage).
