Phosphorus recycling from wastewater to agriculture using reactive filter media
KTH, School of Architecture and the Built Environment (ABE), Land and Water Resources Engineering.
2007 (English)Licentiate thesis, comprehensive summary (Other scientific)
Abstract [en]

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. The selected materials (Filtra P, Polonite and wollastonite) were saturated with P and used as soil amendments in a pot experiment. The amendments tended to improve the yield of barley and ryegrass compared with no P addition. The amendments also increased soil pH, P availability and cation exchange capacity in the studied soils. The substrates studied here can be of particular interest for acid soils. Of the materials studied, Polonite appears to be the most suitable substrate for the recycling of P from wastewater to agriculture

Abstract [en]

Phosphorus sorption capacity ofdifferent types of opoka. The bedrock opoka hasbeen lately reported as an appropriate reactivemedia for onsite wastewater treatment systemsdue to its high phosphorus (P) sorption capacity.However, variations on its chemical compositionmay affect its reactivity with P, therefore leadingto a variable P removal effi ciency. In this paper,the P-sorption capacity of three different typesof opoka from the region of Miechów, Poland,is reported. According to the silica and carbonatecontent, opoka samples were classifi ed as light--weight and heavy-weight opoka. When heatedover 900°C, opoka showed a very high P-sorptioncapacity that was well correlated to its Ca content.P-sorption isotherms from batch experiments withan artifi cial P solution were plotted and fi tted tothe Langmuir and Freundlich adsorption models.The Freundlich isotherm appeared to model betterthe P-sorption of light opoka and the Langmuirisotherm of heavy opoka, suggesting differentdominating mechanisms of P-sorption by lightand heavy opoka.

Abstract [en]

Reactive substrates used in filter systems can reduce phosphorus (P) pollution and, once saturated with P, may be recycled in agriculture. These substrates are usually calcium carbonate derivates with high pH values, which may be particularly beneficial for acid soils. Three reactive substrates (Filtra P, Polonite and wollastonite) saturated with P were used as amendments to an acid soil in a pot experiment. Substrate amendments tended to improve ryegrass yield and P uptake compared with control and potassium phosphate treatments. Polonite produced the highest yield/amendment ratio, while Polonite and Filtra P significantly increased the concentrations of P and Ca in the ryegrass. Addition of all three substrates increased the pH, AL-extractable P and cation exchange capacity of soils during the experiment. These substrates can therefore be applied to acid soils in order to recycle P and improve soil properties.
