A NaCl-modified zeolite was used to simultaneously remove nitrogen and phosphate from biogas slurry. The effect of pH, contact time and dosage of absorbants on the removal efficiency of nitrogen and phosphate were studied. The results showed that the highest removal efficiency of NH4+-N (92.13%) and PO43−-P (90.3%) were achieved at pH 8. While the zeolite doses ranged …

The average and the local structure of phosphorus-treated HZSM-5 zeolites were investigated by means of atom probe tomography, powder X-ray diffraction (at ambient and cryogenic temperatures) and 1 H, 29 Si, 27 Al, and 31 P magic angle spinning (MAS) solid state nuclear magnetic resonance (NMR) spectroscopy. Phosphatation to yield a product with P/Al ≤ 1 …

Phosphorus and microporous aluminosilicates, better known as zeolites, have a unique but poorly understood relationship. For example, phosphatation of the industrially important zeolite H-ZSM-5 is a well-known, relatively inexpensive and seemingly straightforward post-synthetic modification applied by the chemical industry not only to alter its hydrothermal stability and …

Removal of both nutrients ammonium and phosphorus by natural zeolite has been studied in lab scale by using a mechanically stirred batch system (1000. ml).. Zeolite, a mean particle size of 13 μm, was used as an adsorbent for the removal of ammonium and then as a seed material for the precipitation of calcium phosphate.A relationship was established between the uptake of ammonium by zeolite ...

Zeolite rocks are particularly widespread throughout the earth's crust, particularly in the Cenozoic and Mesozoic layers and clinoptilolite is considered as the most common naturally occurring zeolite mineral [11,12,13,14,15]. Zeolites are distributed mainly in regions with a past volcanic history or areas still geologically active today .
