Design of BioGas Plant From Wheat Bran Based Waste Water

Written by

Biogas is a gas which mainly consists of methane (CH4) and carbon-di-oxide (CO2). Biogas can be produced from wastes like kitchen waste, animal manure, agriculture and industrial wastes. Biogas is a clean and renewable from of energy and substitute for conventional sources of energy such as fossil fuels which are causing ecological problems and at the same time depleting at a faster rate. The main aim of the work is to produce biogas from wheat bran based wastewater from Salalah Mills Co. (SAOG). Wastewater was prepared by dissolving 0.2 kg of bran in 5 L of water. Bran wastewater samples were analyzed for sugars, starch, protien, lipids, total solids, total suspended solids, volatile suspended solids,total dissolved solids, ash, pH, chemical oxygen demand, biological oxygen demand and dissolved oxygen .

Results revealed significant reduction in total soluble sugars, starch, total solids, total suspended solids, volatile suspended solids, pH, and chemical oxygen demand and negligible reduction in ash. Hence, anaerobic digestion of bran wastewater is a promising feedstock for biogas production.

Design and Fabrication of Dust Collecting Unit

Written by

Salalah Mills company imports wheat from all over the countries. The imported wheat is stored for grinding to make wheat flour which is used as raw material in various food products. The wheat is transferred from truck to the storage tank via belt conveyers. While transferring, the dust present in the wheat gets mixed in the atmosphere which leads to air pollution. In order to avoid this, students are assigned with the task of designing and fabricating a dust collecting unit which helps in the removal of the dust from the wheat during transfer process. Thus, this project involves design and fabrication of blower, dust collector, duct and hood. In the Phase I, students will design the unit using CAD software then FEA software will be used for analysis & optimization. In the phase II, the dust collecting unit will be fabricated for the purpose.
