Real-Time Monitoring of Microalgal Biomass in Pilot-Scale Photobioreactors Using Nephelometry
نویسندگان
چکیده
The increasing cultivation of microalgae in photobioreactors warrants efficient and non-invasive methods to quantify biomass density real time. Nephelometric turbidity assessment, a method that measures light scatter by particles suspension, was introduced already several decades ago but only recently validated as high-throughput tool monitor biomass. depends on the suspended well their physical properties, so far there are hardly any accounts how nephelometric assessment relates classic such dry weight spectrophotometric measurement across broad range for different species. Here, we monitored online time during semi-continuous three commercial species Chloromonas typhlos, Microchloropsis gaditana Porphyridium purpureum pilot-scale photobioreactors, relate optical density. results confirm relatively strong (R2 = 0.87–0.93) nonlinear relationship between differs among Overall, demonstrate nephelometry can be used microalgal provide necessary means estimate studied from data facilitate automated monitoring.

Comparison of four outdoor pilot-scale photobioreactors
BACKGROUND Microalgae are a potential source of sustainable commodities of fuels, chemicals and food and feed additives. The current high production costs, as a result of the low areal productivities, limit the application of microalgae in industry. A first step is determining how the different production system designs relate to each other under identical climate conditions. The productivity a...

The gasification of pine and mixed-hardwood chips has been carried out in a pilot-scale system at a range of gas flow rates. Consuming w17e30 kgh 1 of feedstock, the producer gas was composed of w200 dm m 3 carbon monoxide, 12 dm m 3 carbon dioxide, 30 dm m 3 methane and 190 dm m 3 hydrogen, with an energy content of w6 MJ m 3 for both feedstocks. It was found that the efficiency of the system ...
متن کاملTreatment of Dairy Wastewater Using Pilot Scale Tricking Filter
A pilot scale trickling filter and secondary sedimentation are used to evaluate the feasibility of this process for the treatment of raw dairy waste. The BOD in the raw waste of 252 to 1200 mg/l is reduced 50-73% by a single stage and a further 17-55% by sedimentation tank. Treatment efficiencies are determined at various waste strengths and influent flow rates. With a loading rate of 5-12 kg B...
