Title: QUALITY ASSESSMENT OF TREATED WATER SUPPLY: A CASE STUDY OF MINNA, NIGERIA Authors: Musa, Umaru; Mohammed, Ibrahim Aris; MUAZU, Sagir; BALA, Alhaji Abstract: Abstract There is global call for sufficient water supply and sanitation as large percent of world population lack access to safe drinking water basic sanitation. This paper investigates the level Of purity In public water supply in Minna. Treated water from a Minna water treatment plant was collected and analyzed for its physico-chemical properties, such as PH, Total Dissolve Solid (TDS), Electrical conductivity (EC), Temperature CC), Turbrdity (TB), Nitrate (NIT), Total Alkalinity(TAL), and Total Hardness (TOH). The study revealed that the water supply from the treatment plant was not wholesomely fit for consumption as some Of the measured properties such as turbidity and iron content do not conform to the set standard by the World Health Organization (WHO) and the Nationa/Agency for and Drug Administration and Control (NAFDAC).

Title: Kinetic Modeling of Rice Husk Components Pyrolysis Based on Independent Parallel Reactions Authors: Garba, Umar Garba; Charles, S.G; Bilyaminu, Suleiman; Mohammed, Alhassan; Musa, Umaru; Isa, A.G Abstract: This study presents the pyrolysis mechanism of rice husk in nitrogen atmosphere by thermogravimetric analysis (TGA). The thermal decomposition wasout in three stages: moisture removal(18--200 oc), main devolatilization 200- 400 oc) and continuous slight devolatilization (400 oc). The weight loss of rice husk was based on the assumption that lignocellulose components (cellulose, hemicellulose and lignin) undergo pyrolysis independently in parallel first-order reactions. The kinetic parameters of the three lignocellulose components were determined by means of Microsoft Excel Solver tool using least square algorithrn. The result of thermal degradation of rice husk samples shows that the predictions of the cellulose, hemicellulose and lignin components with the experiments. The activation energy and pre-exponential factors of cellulose, hemicellulose and lignin are 187kJ/mol and 1.2x 10^15 min^-1, 29kJ/mol and 1.6x10^7min^-1 and 90 kJ/mol and 1.8 x 10^-1. The results suggest that thermal rate of cellulose was found to be higher, whereas that of lignin decomposition rate was lower. The thermal of hemicellulose decomposition was intermediate.

Title: Inu•stigntion into the Refractory Properties of Tntiko and Clays Authors: Musa, Umaru; Aliyu, Musa Aliyu; Aminu, H Abstract: This study undertakes the characterisation and analysis of two clay samples obtained from Tatiko and of Niger State, Nig«ia to determine their suitability for use as refractories. Chemical analysis was carried out using atomic absorption spectrophotometry (AAS) methods and both clays were found to of similar composition with high silica, moderate alumina and low ferric oxide content with trace quantities of magnesium and calcium oxides. The results of physical tests conducted show low cold crushing strength (15.8 and 16.6 KN/m2 respectively for Tatiko and Beji clay) fair refractoriness (1300 and 1350 C) bul very good linear shrinkage (both below 1.4%) and fair thermal shock resistance (at 10 and 9 cycle). These properties make Beji and Tatiko clays good for handling low melting metals, paint, chalk and earthenware

Title: Effects of Catalyst Type and Concentration on Biodiesel Yield and Quality Authors: Mohammed, Ibrahim Aris; Musa, Umaru; Sadiq, M.M; Aliyu, Musa Aliyu; Isah, A.G; Omoniyi, Ronke Abstract: This paper present study report the effect of catalyst type and concentration on yield and quality of biodiesel prtxluced from cotton seed oil. This was achieved through the production of bicxliesel from refined cottonseed oil via the transesterification process by studying the effects of various catalysts on biodiesel yield. The catalysts studied include; hydroxide, hydroxide, iron sulphate and potassium carbonate at different concentrations. The yield of biodiesel decreased with increase in catalyst concentration from 0.25 to 0.75 wt % thus, highest conversion was obtained at 0.25 wt % concentration for sodium hydroxide (NaOH), potassium hydroxide (KOH), iron sulphate (FeS04) and potassium carbonate (K2C03) catalysts with coresponding yields Of 96 0/0, 94 0/0, 92 0/0 and 82 0/0. The fuel properties from the transesterified refined cottonseed oil show its suitability with the ASTM standard for the production of biodiesel. Description: CONFERENCE PROCEEDING
