Tile drained land with phosphorus (P)-rich topsoil is prone to P loss, which can impair surface water quality via eutrophication. We used by-products from steel and energy industries to mitigate P loss from tile drains. For each by-product, P sorption maximum (P(max)) and strength (k) were determined, while a fluvarium trial assessed P uptake with flow rate. Although two ash materials (fly ash ...

Steel converter slag, also called Linz-Donawitz (LD) has been considered as an oxygen carrier for biofuel chemical looping applications due to its high availability. In addition content of iron which contributes oxygen-carrying capacity, LD slag contains a significant amount calcium. Calcium, however, is known interact with sulfur, may affect the usability slag. To get better understanding inte...

It is well documented that slag-based silicon fertilizers have beneficial effects on the growth and disease resistance of rice. However, their effects vary greatly with sources of slag and are closely related to availability of silicon (Si) in these materials. To date, few researches have been done to compare the differences in plant performance and disease resistance between different slag-bas...

The study conducted the research aimed to obtaining a porous glass-crystalline materials based on glass cullet and converter slag, which was used as gas-forming additive. In this work, chemical phase compositions of studied slag were analyzed, differential thermal analysis its sample carried out. Converter added composition masses in an amount 2.5 30 wt%, rest cullet. Вurning samples out temper...

PURPOSE A former wood exploitation revealing high Cu and As concentration of the soils served as a case study for assisted phytoextraction. METHOD P-spiked Linz-Donawitz (LD) slag was used as a soil additive to improve physico-chemical soil properties and in situ stabilize Cu and other trace metals in a sandy Cu-contaminated soil (630 mg kg⁻¹ soil). The LD slag was incorporated into the conta...

Laboratory scale studies have repeatedly reported high P-retention in slag, a by-product of the steel manufacturing industry. Thus, it has emerged as a potential material to increase P-removal from constructed wetlands (CWs). However, several limitations were highlighted by field experiments, including the high pH of treated water and clogging. We hypothesized that the addition of sedimentary r...
