1. Phosphorus recycling from wastewater to agriculture using reactive filter media
Abstract : This thesis focused on testing the suitability of reactive filter media used for phosphorus (P) removal from wastewater as fertilizers, thus recycling P to agriculture. The work compared the P sorption capacity of several materials in order to assess their suitability as a source of P for plants. READ MORE

3. Phosphorus removal in reactive filter materials : factors affecting the sorption capacity
Abstract : Phosphorus is an essential component in all living organisms; it is one of the components of the DNA and the key element in the energy supplying molecule adenosine triphosphate (ATP). Throughout the history, humans have been recycling phosphorus to agriculture; thereby increasing the yield, examples of this includes the burning of plants and the use of manure. READ MORE

4. Phosphorus availability and microbial respiration across biomes : from plantation forest to tundra
Abstract : Phosphorus is the main limiting nutrient for plant growth in large areas of the world and the availability of phosphorus to plants and microbes can be strongly affected by soil properties. Even though the phosphorus cycle has been studied extensively, much remains unknown about the key processes governing phosphorus availability in different environments. READ MORE

5. On-site wastewater treatment : Polonite and other filter materials for removal of metals, nitrogen and phosphorus
Abstract : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. READ MORE
