Bio Gas Production from waste water sludge

Written by

Municipal wastewater treatment plants generate sludge as a by-product of the physical, chemical and biological processes used in the treatment of wastewater. Generally, this sludge must be subject to some form of treatment in order to alter its character. By using anaerobic digestion in the treatment of wastewater sludge, methane gas is produced and it is known as biogas. It must not only be seen as a renewable energy source, but even more as one of the promising solutions to the large environmental problem concerning waste handling, water pollution, CO2 emission, etc

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.

Biodiesel has gained widespread importance in recent years as an alternative, renewable liquid transportation fuel. It is derived from natural triglycerides in the presence of an alcohol and an alkali catalyst via a transesterification reaction. To date, transesterification based on the use of chemical catalysts has been predominant for biodiesel production at the industrial scale due to its high conversion efficiency at reasonable cost. Recently, biocatalytic transesterification has received considerable attention due to its favorable conversion rate and relatively simple downstream processing demands for the recovery of by‐products and purification of biodiesel. Biocatalysis of the transesterification reaction using commercially purified lipase represents a major cost constraint.

However, more cost‐effective techniques based on the immobilization of both extracellular and intracellular lipases on support materials facilitate the reusability of the catalyst. Other variables, including the presence of alcohol, glycerol and the activity of water can profoundly affect lipase activity and stability during the reaction. This review evaluates the current status for lipase biocatalyst‐mediated production of biodiesel, and identifies the key parameters affecting lipase activity and stability. Pioneer studies on reactor‐based lipase conversion of triglycerides are presented

Fabrication of Fixtures for Mass Painting on Sand Cores

Written by

A core is a device used in casting and molding processes to produce internal cavities and reentrant angles and is normally a disposable item that is destroyed to get it out of the piece. Such cores are painted individually with graphite paint to create a fine surface finish in the castings, To improve the productivity a fixture can be used to huge numbers of cores simultaneously to reduce production time and improve production rate.

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.

Design of an Industrial Gear Box

Written by

An Industrial gear box used for running Kiln in Raysut Cement company was taken as a part of project work. The project involves upgrading the RPM from current 3.85 rpm to 5 rpm. In connection with this students will be exposed to complete designing aspects of a gear box. The designing involves design of planetary gear system , design of shafts and bearings.

Carbon bearings have been in use at ‘Salalah Methanol Company’ to lift the waste water, and to supply it to the treatment plant. The bearings have been a part of vertical centrifugal pump that supplies the water to the treatment plant. In the process of transferring, there persists a frequent breakdown of the bearings and needs a replacement once in every two months. Thus, the project aims towards analyzing the cause of failure of these bearings.
