State-of-the-art Technology to Stabilize Heavy Metal in Municipal Solid Waste Incineration Fly Ash Using Natural Zeolite | Chapter 1 | Novel Perspectives of Geography, Environment and Earth Sciences Vol. 6

 Stabilizing difficult metals in Municipal Solid Waste Incineration (MSWI) fly ruins by using open zeolite is one of the state-of-the-skill technologies. The current study attracted on the sorption process of heavy metals by requesting mordenite, an inexpensive open zeolite adsorbent, and assessing the productiveness of the treatment of fly ruins. Batch experiments were conducted to review the effects of the powerful parameters, to a degree the initial ore ion concentration, the liquid-to-solid (L/S) percentage, the dosage of the adsorbent, and the evenness concentration of the mineral, on the immobilization of Pb2+ and Zn2+. Heavy metal counterweight efficiency increased accompanying increasing the portion of drug or other consumable of mordenite, influenced for one media-distinguishing surface area. Heavy metal adsorption is from various adsorption processes and ion exchange mechanisms. The Langmuir and Freundlich isotherm models were examined using the adsorption dossier. The adsorption process is better in the Freundlich isotherm model with a extreme determination cooperative (R2), especially for the adsorption of Pb2+. The effects raise hopes for the use of mordenite as a low-cost substance to treat MSWI flee ash. The verdicts indicate that harmonized (Pb2+ and Zn2+) immobilization by mordenite is technically doable and seems expected very effective. Furthermore, treated flee ash can be secondhand as a construction material.

The First Reference of the Effect of the Syrian Natural Zeolite on Airborne Microorganism Pollution of Broiler Farms | Chapter 5 | Recent Progress in Science and Technology Vol. 8

 The purpose of this study was to investigate the effect of three different levels of Syrian natural zeolite on the bacterial load concentrations in the air of broilers farms for six weeks. The broiler farms are considered as a reservoir of pathogenic microorganism. This research was carried out  in private commercial broiler farm in the Lattakia Governorate, Syria During spring (from March to April) and autumn (from October to November) seasons. In the experiment, commercial broiler hybrid (Roos 308), with a total number (3000), were randomly assigned to four groups. This experiment was created using complete randomization, and each group (750 birds) has three replicates with 250 birds in each replicate (in addition to the control section). The findings revealed that the concentrations value for Staphylococcus spp. during spring, at the sixth week of the fattening period, in the treatment Tz3 (75%) was recorded 7.0×105, while in autumn; the value was 7.4×105 CFU/m3. And for Escherichia coli in spring, was 8.4×103 and in the autumn 8.8×103 CFU/m3. According to the findings, adding Syrian natural zeolite to broiler litter resulted in a significantly (p<0.05) lower concentration of airborne bacteria at the end of the experiment, with a superior effect to Tz3 treatment in the internal air, and the lowest concentration was observed in spring compared to autumn. This result serves as a guide for the optimal use of the various ratios of Syrian natural zeolite, as well as the development of new methods for reducing airborne microorganisms in broiler farms.
