“…Another possible mechanism urging removal efficiency of the clay mixtures can be attributed to pozzolanic reactions [28,29]. The pozzolanic reaction generally involves a primary chemical adsorption of calcium compound on the surface of silanol groups [30].…”

“…These researchers investigated a number of different filter materials (both natural and man-made materials) available in Sweden, with regard to their capacities to remove P from a variety of wastewaters. Among these materials, blast furnace slag (BFS) has attracted attention by several researchers, not only in Sweden but also elsewhere in the world [11][12][13][14][15][16][17].…”

Abstract:Research on Phosphorus (P) removal capacity by blast furnace slags (BFS) has been undertaken in Sweden for the last decade. Both laboratory experiments and field trials have been carried out. While laboratory investigations revealed that BFS has a high P-sorption capacity (95-100%), P removal in field trials was much lower, ranging from 40 to 53%. In addition, a number of problems have been observed in BFS field testing including clogging, sulfuric odor and environmental (regulatory) concerns about possible leaching of heavy metals from the slag. In spite of these problems, and questioning by the environmental regulatory authorities, research continues to provide evidence that BFS can be regarded as a suitable filter media, and attempts have also been undertaken in order to further improve the P-removal capacity of this adsorbing material.

“…Phosphorus recovery using adsorption processes has received considerable attention because of its efficiency and simplicity compared to biological methods, aggregation-sedimentation and crystallization processes [2]. Many adsorbents, derived from industrial by-products, have been reported to be used for phosphorus removal, such as Ca-and Fe-based adsorbents using dehydrated lime and blast furnace slag [5], lanthanum-loaded SiO 2 [6] and zirconium-loaded activated carbon [7]. Agricultural byproducts, e.g., orange waste obtained just after juicing, are major solid wastes produced by the food industry.…”

Zirconium was loaded onto orange waste, a cheap and available agricultural waste in Japan, to investigate the feasibility of its utilization for phosphorus recovery from secondary effluent and side-stream liquid, which contain 5.9 and 68.2 mg/dm 3 phosphorus, respectively. The phosphorus removal from side-stream liquid by using zirconium-loaded saponified orange waste (Zr-SOW) gel increased with an increasing solid/liquid ratio, and it was found that Zr-SOW gel showed better performance than zirconium ferrite. The prepared adsorbent was effective for phosphorus removal and exhibited a reasonably high adsorption capacity, twice than that of zirconium ferrite. The secondary effluent was treated in a column packed with Zr-SOW gel, and an dynamic adsorption capacity of 1.3 mol-P/ kg was attained. The adsorbed phosphorus from the column was successfully eluted as a concentrated form by using a small amount of 0.2 M NaOH. Throughout the elution process, zirconium was not leaked from the adsorption gel.
