“…Der mit Austern versetzte Beton zeigt die gleiche Druckfestigkeit im Vergleich zu Standardbeton. Eine weitere Reihe von Forschungsarbeiten nutzte die Schalen als absorbierende Matrix, um Schadstoffe aus Gewässern zu entfernen . Als zu absorbierende Elemente wurden Kupfer , Phosphor , und größere Moleküle wie Methylenblau untersucht.…”

Austernschalen stellen als Abfallprodukt eine große Umweltbelastung dar und die Wiederverwendung des Materials gewinnt zunehmend an Bedeutung. Da der Zerkleinerungsprozess beim Recycling von Sekundärrohstoffen die Eigenschaften des Materials definiert, wurden Austernschalen mit einer Planetenkugelmühle und einer Schlagradmühle zerkleinert und die gewonnenen Fraktionen in Bezug auf Größe und Form analysiert und miteinander verglichen. Ein Zerkleinerungsmaterial der Schlagradmühle wurde für eine Reihe von Benetzungsversuchen verwendet, die dazu beitrugen, die freie Oberflächenenergie des Materials nachzuweisen.

“…Owing to its advantages such as low cost, sustainability, nontoxicity to humans, and environmental friendliness, OS is expected to be an appropriate natural precursor material [18,19]. With its porous structure, modified OS is commonly used to adsorb heavy metals and dyes [20,21,22,23]. However, its adsorption capacity is limited.…”

Micro-nano composite material was prepared to adsorb Hg(II) ions via the co-precipitation method. Oyster shell (OS), Fe3O4 nanoparticles, and humic acid (HA) were used as the raw materials. The adhesion of nanoparticles to OS displayed by scanning electron microscopy (SEM), the appearance of the (311) plane of standard Fe3O4 derived from X-ray diffraction (XRD), and the transformation of pore sizes to 50 nm and 20 μm by mercury intrusion porosimetry (MIP) jointly revealed the successful grafting of HA-functionalized Fe3O4 onto the oyster shell surface. The vibrating sample magnetometer (VSM) results showed superparamagnetic properties of the novel adsorbent. The adsorption mechanism was investigated based on X-ray photoelectron spectroscopy (XPS) techniques, which showed the process of physicochemical adsorption while mercury was adsorbed as Hg(II). The effects of pH (3–7), initial solution concentration (2.5–30 mg·L−1), and contact time (0–5 h) on the adsorption of Hg(II) ions were studied in detail. The experimental data were well fitted to the Langmuir isotherm equation (R2 = 0.991) and were shown to follow a pseudo-second-order reaction model (R2 = 0.998). The maximum adsorption capacity of Hg(II) was shown to be 141.57 mg·g−1. In addition, this new adsorbent exhibited excellent selectivity.

“…Water purification for cultivating water spinach or sweet basil by a recirculation aquaponic system was investigated either an oyster shell or ceramic ring. Some results showed that oyster shell significantly increased the pH and calcium in the effluent, which supports the growth of a biofilm, leading to good nitrification (Hsing Yuan Yen et al, 2016). The inorganic compounds was discussed that it had influence on the thermodynamic characteristics of the composite film, so the flow changes of hydrodynamic behavior were much lower than that of the control film of cellulose acetate (A.M. Pandele et al, 2017).…”

This article discussed the lifetime of catalyst on cost effect for catalytic combustion furnace and applications of pottery heated by catalytic combustion furnace in purification water. The time of start-up process rises with the increase of the number of ignition. The catalyst sintering was remarkable. By reducing the number of ignition and adjusting the temperature rise uniformly in the furnace, the efficient utilization of thermal energy could be realized to saving production cost and extending the lifetime of catalyst. With exquisite and even-textured surface the pottery had striking purification effect on water. The water purification material of this pottery was applied to the sedimentation tank, which had remarkable water purification efficiency and could save the operating cost of the water treatment system.
