Effect of dolomite on pyrolysis of rice straw
(2013)A study of catalytic pyrolysis on rice straw was carried out in a fixed-bed reactor. The objectives were to determine the effect of dolomite catalyst on the distribution of product yield and bio-oil characterization. The ... -
Human health risk assessment of chlorinated disinfection by-products in drinking water using a probabilistic approach
(Elsevier Limited, 2008-07)The presence of chlorinated disinfection by-products (DBPs) in drinking water is a public health issue, due to their possible adverse health effects on humans. To gauge the risk of chlorinated DBPs on human health, a risk ... -
Mechanism of turbidity and hardness removal in hard water sources by using Moringa oleifera
(Asian Network for Scientific, 2011)The objective of this study was to describe the mechanism of simultaneous removal of hardness and background turbidity in hard water for drinking water purpose by using Moringa oleifera (MO) that extracted with 1.0 M sodium ... -
Performance evaluation of okra (abelmoschus esculentus) as coagulant for turbidity removal in water treatment
(Trans Tech Publications, 2014)The objective of this study is to evaluate the performance of turbidity removal in water by using Okra (Abelmoschus esculentus) as natural coagulant. The coagulation active agent in various Okra sections was extracted with ... -
Thermogravimetric analysis and the optimisation of bio-oil yield from fixed-bed pyrolysis of rice husk using response surface methodology (RSM)
(Elsevier B. V., 2011-03)The effects of pyrolysis temperature, heating rate, particle size, holding time, and gas flow rate were investigated to optimize bio-oil yield from rice husk pyrolysis. Thermogravimetric analysis showed thermal degradation ... -
