“…Similar results also for fine-grain particles (1-2 mm) were occurred for carbonate-siliceous rock (opoka) heated in temperature 900 °C. Efficiency of phosphorus removal reached to 97 % [2]. Those study was proceeded with flow conditions in models of filters with vertical flow.…”

Abstract. In the light of the need to find an effective way to remove phosphorus from wastewater, studies on the suitability of sorption materials in this process should be conducted. The aim of the study was to examine the potential benefits of using selected adsorbents to reduce orthophosphates from the model solution under steady conditions. The study was conducted on a laboratory scale using synthetic wastewater with concentration of P-PO4 in the range of 5-100 mg/dm3. Experiment has shown that fine-grained material M1 (0-2 mm) is highly effective at removal of phosphorus compounds at the level of 97.8% at the highest concentration of P-PO4. The sorption capacity achieved during the investigation was 9.6 mg/g, while the maximum sorption capacity from the Langmuir model could reach up to 256 mg/g. Material M2 (2-8 mm) did not show satisfactory sorption capacity (maximum calculated sorption capacity: 0.36 mg/g) and the effectiveness of phosphate reduction did not exceeded 6% at the lowest concentration of P-PO4.

“…In addition to silica and calcium, opoka can also include: [13]. However, the quantitative and qualitative compositions of opoka may vary, depending on its origin [13,14]. Owing to their thermal and mechanical properties, opokas find application in the building industry, cement production, road construction, river revetment, and the manufacture of decorative lining and ceramic materials [10][11][12]15].…”

Application of in-line rheological measurements for characterization of polypropylene/opoka rock powder composites

The rheological properties of the composites of polypropylene (PP) with a new natural powder hybrid filler-carbonate-silicate rock called opoka-were investigated. Opoka rock is industrial waste originating (as a subsieve fraction) from the production of sorbents used in water treatment processes. The effect of opoka addition (1, 5 and 10 wt %) on the processability of PP was determined during the extrusion process using an in-line measuring stand. The testing instrument was an extruder rheometer equipped with a rheological measuring head with exchangeable dies. Cylindrical measuring dies with a radius of 1.5 mm and a length of L = 20, 30, 40 and 50 mm, respectively, were used in the measurements. The rheological parameters of the composites were determined based on the Ostwald-de-Waele power-law model at a temperature of 230 °C. The effect of the addition of opoka on the extruder operating characteristic, flow curves, viscosity curves, and the values of power law index (n), consistency factor (K), mass flow rate (MFR) and volume flow rate (MVR) have been determined.

“…The research carried out in recent years on the use of new rock raw materials as sorbents in environmental protection is increasingly pointing at the possibility of the opoka-rocks gaining use in this way. The literature data indicate that when used as an additional technological element, they give better results in removing total phosphorus from domestic waters and wastewaters [Jóźwiakowski K. et al 2017]. The capacity to bind phosphorus noted for opoka-rock as a result of laboratory tests is between 12.3 and 25.5 mg P-PO4 • g -1 [Bus A. and Karczmarczyk A., 2014].…”

During the exploitation of the Bełchatów lignite deposit at the point of contact between the Mesozoic substrate and Neogene deposits, the rocks of different petrographic composition were found. The group of rocks with transitional features between carbonate and silica rocks were called opoka-rock. This article presents the current state of knowledge on the geological conditions pertaining to the occurrence of the Bełchatów opoka-rock, and on its petrographic and chemical characteristics. An analysis was also carried out to determine the physical, mechanical as well as raw-material properties, as well as the related issue of potential utilisation.
