Estimation of algae concentration in water solutions using spectrophotometry measurements and absorbance first derivative
( TechConnect , 2016 , Conference Paper)The monitoring and detection of algae in wastewater and surface solutions is important in controlling the quality of surface water and wastewater, yet there is currently no quick and simple method to achieve this. The ... -
Ethanol dehydrogenation mechanism on cuni catalysts for hydrogen production
( TechConnect , 2016 , Conference Paper)Ethanol dehydrogenation mechanism was investigated over catalysts containing Cu and Ni metals prepared by solution combustion synthesis. In situ DRIFTS studies were conducted on individual metals (Cu and Ni) as well as on ... -
Heat powered water pump for reverse osmosis desalination
( TechConnect , 2016 , Conference Paper)Current desalination techniques are typically very energy intensive: energy consumption can account for up to 70% of the desalination costs. To improve economics of water desalination plants innovative energy efficient, ... -
Kinetic and thermodynamic investigation of CO2 adsorption-desorption on polyethyleneimine - Mesoporous silica
( TechConnect , 2016 , Conference Paper)Two CO2 solid sorbents based on polyethyleneimine, PEI (432 and 10k) impregnated into mesoporous silica (MPS) foam were synthesized and tested for CO2 capture. At ambient pressure, the amount of CO2 captured by these solid ... -
Potential for green algae spirulina to capture carbon dioxide from gas stream
( TechConnect , 2016 , Conference Paper)This study evaluated the use of green algae Spirulina microalgae as a C02 capturing technology at different temperatures. The growth of Spirulina at 25 and 30◦C were studied in synthetic wastewater and its performance in ... -
Sustained solar fuel production in multiple thermochemical cycles using sol-gel derived ferrite nanopowders
( TechConnect , 2016 , Conference Paper)In this paper, the sol-gel synthesis of Mg-doped Niferrite i.e. Ni-Mg-ferrite was attempted by using propylene oxide (PO) as a proton scvanger. Effects of two important synthesis paramaters such as amount of PO added during ... -
The effect of intermediate ozonation process on improving biogas production from co-digestion of agricultural waste and manure
( TechConnect , 2016 , Conference Paper)Anaerobic co-digestion of agricultural solid waste, wastewater, and manure was evaluated in batch reactor. The performance of anaerobic digestion (AD) was monitored by assessing the methane production potential, maximum ... -
Thermochemical copper Oxide - Copper sulfate water splitting cycle for solar hydrogen production
( TechConnect , 2016 , Conference Paper)In this paper, the solar thermochemical copper oxide - copper sulfate (CO-CS) water splitting cycle is thermodynamically investigated. CO-CS cycle consists of two steps: first step - exothermic oxidation of CuO via water ...
