Development of a hydrogen gas purifier for improving the quality of biogas in fermentation process

Hydrogen sulfide (H25 cheap materials activated carbon scraped iron sand cement and rice husks applied to the small scale biogas production at 30 ppm within 6 hours. The filter materials with highest to lowest H48.18 percent respectively. In the medium scale biogas production (20 L) at 30 ppm. Scraped iron and sand mixed with activated carbon filter had the best H(200 L) production of the biogas fermentation (30 ppm biogas product) sand mixed with activated carbon filter at the ratio 60:40 displayed the best performances in removing H2(3 day). It is the most environmental friendliness as well as cost-effective filter for biogas fermentation at scale up sizes at least 20 L. S) is found to be one major serious contaminant to biogas production system. In this research the team aimed to develop a high efficient filter for removing H2S from the biogas reaction. From all 2S absorptivity were activated carbon sand scraped iron and rice husks those accounted for 88.02 76.06 55 50 and 2S absorptivity (100 percent) and sand showed its H2S removal efficiency lower at 65 percent respectively. In larger scale S after incubated for 4.5 hours while scraped iron filter as well as activated carbon filter functioned in H2S removal longer time (2 and 3 days respectively). In order to be able to practically apply for continuous filtering H2S from the continuous biogas production sand mixed with activated carbon filter exhibited long last filtration

The objectives of this study were to examine the royalty of customers categorized according to population properties and to investigate the relationship between service quality and royalty of customers. The data were collected from 288 existing customers through the application of questionnaires. The statistics applied for the data analysis comprise Percentage Mean Frequency Minimum Maximum Standard deviation Independent Samples t-test One-way ANOVA and Scheffe’s Method between 0.01 to 0.05 level of significance. The study demonstrated that the differences in gender and education had influences on the royalty of customers at 0.05 level of significance while there is no significant differences in age job and monthly income. Overall it was found that the service quality had a positive relationship with the royalty of customers at 0.01 level of significance.
