with high removal efficiency of contaminants such as nitrogen, phosphorus, bacteria, bio-chemical oxygen demand, and total suspended solids. The membrane filtration system in effect can replace the secondary clarifier and sand fil-ters in a typical activated sludge treatment system. Membrane filtration allows a higher
In this study, in situ fibrous bed bioreactor (isFBB) was developed at the first time for efficient succinic acid (SA) production by Yarrowia lipolytica. After optimization, SA titer, productivity and yield of 51.9g/L, 1.46g/L/h and 0.42g/g were obtained respectively via isFBB fermentation under con
Nov 5, 2020 · Membrane bioreactors (MBRs) have proven to be one of the most effective technologies globally for treating wastewater from different sources 1,2,3.In MBRs operation, wastewater treatment is
Apr 3, 2024 · Due to high efficiency, airlift bioreactors are sometimes preferred e.g., methanol production, waste water treatment, single-cell protein production. 4. Packed Bed Reactors. A packed bed fermentor is a type of bioreactor that consists of a bed of solid particles with biocatalyst either on or within the matrix of solids.
Feb 2, 2023 · The development of low-cost and high-performing membrane materials is an area that should be focused on to bring about more-effective MBR technologies. Nanomaterial membrane bioreactors provide benefits such as lower membrane fouling and enhanced pollutant removal efficiency.
In this study, a high-efficiency honeycomb fixed-bed bioreactor was built for a pilot project. After determining the operating environment parameters of the reactor (dissolved oxygen (DO), pH, and temperature), microorganisms were collected by measuring the water quality changes in inlet and outlet water.
Microfluidic biocatalytic reactors have attracted widespread attention in recent years, but the production cost is generally high, which makes it difficult to meet the needs of large-scale industrial production. Developing a low-cost, green fluid reactor has become an urgent requirement.
Jun 1, 2004 · To enhance cell growth and maintain high rate of viability for long-term culture of yew cells in bioreactor, final cell volume less than 50% in SCV seemed to be the best.
This chapter describes a protocol for using a random positioning machine bioreactor to culture human PSCs and the large-scale production of HPCs. Techniques for characterizing the differentiated cells and assessing the efficiency of hematopoietic differentiation in the bioreactor with immunostaining and flow cytometry are also presented.
Dec 1, 2015 · The denitrifying bioreactor was designed to keep the peak flows, with low N and P concentrations, flowing through the top of the reactor while channeling the low-gradient flows with high N and P concentrations in the biological reaction zone at the bottom of the reactor. This ensures unobstructed drainage and high nutrient removal efficiency. 2.2.
Nov 28, 2023 · In a HID production bioreactor, the inoculation density is as much as 20× higher than traditional fed-batch bioreactors, which is achieved using a perfusion culture in the N-1 stage to generate the dense inoculum source. 8 This process shifts the burden of the cell growth phase to the N-1 stage, while enabling the N stage bioreactor to
