Mixing various materials to adjust the ratio of carbon to nitrogen (C/N) of the fermentation raw materials so as to enhance the gas production performance has become a research hotspot and an important development direction of anaerobic fermentation technology, as a result of extensive sources of the raw materials for anaerobic fermentation[3~6].
Materials and methods Materials and pretreatment.
In this study, ratio of the raw materials was the main factor influencing anaerobic fermentation process, as the initial TS load, type and amount of inoculum, pretreatment of raw materials were all the same in the five treatments.

Development and Comparative Analysis of Aluminosilicate Based Ceramic Filters for Ground Water Defluoridation Johnson Kwame Efavia*, Abu Yayaa, SolomonAdebornaa, Julius Fobilb aDepartment of Materials Science and Engineering, University of Ghana, Legon bDepartment of Biological, Environmental and Occupational Health Sciences School of Public Health University of Ghana, Legon *Corresponding Author: Materials Science and Engineering Department, University of Ghana, Legon, Accra-Ghana.
This worktherefore seeks to developcheap, efficient and sustainable porous ceramic bodies (filters) from alumino-silicates (Al oxides) based materials for the potential adsorption of fluoride ions from contaminated water bodies in the Bongo district of Ghana to levels accepted by WHO standards [13,14].
Materials &Methods Raw Materials and Preparation The porous media (filter) used for this investigation was based on aluminosilicates and includes Anfoega clay deposits in Anfoega- Volta region of Ghana, Kibi Kaolin deposits in Kibi- Eastern region of Ghana.
We then sized the ground samples using a sieve stack of:500µm, 355µm, 90µm and 63µm.Saw dust was used for the formation of pores in the aluminosilicates materials (Anfoega clay, Kibi Kaolin and Laterite as well as Termataria Earth).
