Treatment of oilfield produced water was investigated using an anaerobic process coupled with micro-electrolysis (ME), focusing on changes in chemical oxygen demand (COD) and biodegradability. Results showed that COD exhibited an abnormal change in the single anaerobic system in which it increased within the first 168 hr, but then decreased to 222 mg/L after 360 hr. The biological oxygen demand...

the aim of this study was to evaluate the effect of substitution of soybean meal with canola meal and measure its effects on rumen anaerobic fungal population in lactation iranian of holstein cows. from d 5 to 56 postpartum, cows were fed diets that were isoenergetic containing soybean meal (sbm; n = 3) or canola meal (cm; n = 3). cows were housed in tie stalls and fed tmr two times a day. comp...

This study explores the hypothesis that Magnetic Resonance Imaging (MRI) can image the process of electrolysis by detecting pH fronts. The study has relevance to real time control of cell ablation with electrolysis. To investigate the hypothesis we compare the following MR imaging sequences: T1 weighted, T2 weighted and Proton Density (PD), with optical images acquired using pH-sensitive dyes e...

A software product typically goes through many “upgrades” (version changes) over its lifetime. Reactive systems, such as email clients, software agents, proxies, traffic controllers, and telephone switches are no exception. Evolving such stateful systems is made difficult by the fact that new versions of the software must deal correctly with legacy instances. Users of earlier versions have inve...

The negative energy balance of wastewater treatment could be reversed if anaerobic technologies were implemented for organic carbon oxidation and phototrophic technologies were utilized for nutrient recovery. To characterize the potential for energy positive wastewater treatment by anaerobic and phototrophic biotechnologies we performed a comprehensive literature review and analysis, focusing o...

This paper deals with the application of electrolysis technology for the selective control of marine algal species. The sensitivity of different marine algal species to electrolysis may be different due to their size and structural differences. Electrolysis experiments were conducted using four algal species, namely Chlorella spp., Chaetoceros spp., Isochrysis spp. and Tetraselmis spp. Batch an...

This work presents a new electrolysis-based microelectromechanical systems (MEMS) diaphragm actuator. Electrolysis is a technique for converting electrical energy to pneumatic energy. Theoretically electrolysis can achieve a strain of 136 000% and is capable of generating a pressure above 200 MPa. Electrolysis actuators require modest electrical power and produce minimal heat. Due to the large ...

  Performance and capacity of sulfur recovery unit (SRU) are greatly affected by the H2S:CO2 ratio of the acid gas stream. The acid gases in Iran contain around 35 mol% H2S and 60 mol% CO2. This low concentration of H2S calls for more complex sulfur plant, larger equipments, and higher costs. Acid gas enrichment processes (AGE) is run to upgrade low quality acid gas collected from gas treating...

This article presents future trends in research using microbiological methods to intensify bioprocesses for biogas production. The pretreatment by combinations of physical and chemical methods, such as cavitation electrolysis, is considered. approach the involved reviewing residual area on intensification technologies anaerobic digestion with current improve quality quantity biogas. most valuab...
