hydrocyclone cell harvesting

Hydrocyclone an overview ScienceDirect Topics

Hydrocyclones, although relatively low-energy devices (0.3 kW h m − 3) compared to other harvesting methods, are reported to be an unreliable means of concentrating microalgae as they achieve a maximum concentration of only 0.4% with a concentration factor of 4 (Molina-Grima et al., 2003).

A two-step microengineered system for high-density cell

In our previous study, we demonstrated a 3D printed mini-hydrocyclone for harvesting microalgae cells . Building upon this, the present study will further scale down the design to fabricate an optically transparent micro-hydrocyclone using 3D printing and softlithography. Since the efficiency of micro-hydrocyclones is relatively low, we

Hydrocyclones an overview ScienceDirect Topics

Hydrocyclones are very widely used for high-throughput coarse/fine particle separation in the mineral processing industry using a vortex effect, or simply slurry dewatering. They don’t suffer from the rate-limiting steps of the alternatives: • Sedimentation settling: rate-limiting step is the sedimentation rate.

Use of Hydrocyclones for Mammalian Cell Retention

A hydrocyclone with a volume of 2.56 cm 3 was studied as a potential cell retention device for mammalian cell cultures (6 L volume). For the feasible operation range (0.9 to 1.6 L/min flow corresponding to pressure drops of 0.4 to 1.3 bar) the hydrocyclone was characterized with regard to flow split (underflow‐to‐overflow ratio) and flow ratio (underflow to supply).

Harvesting of microalgae by centrifugation for biodiesel

Oct 01, 2020· Gregg et al. reported a low harvesting efficiency for particles smaller than 400 μm using hydrocyclones for the harvesting of green algae. In terms of cell damage, a hydrocyclone is predicted to cause a certain level of mechanical disruption, however, there is a lack of specialized studies on its effect for large colonial microalgae .

2.4 Effect of Hydrocyclone Operation on Cell Viability The bioreactor was inoculated at a concentration of 2×105 cells/mL. When the cell concentration reached 1.6– 2.0×106 cells/mL, the hydrocyclone (with an overflow diam-eter of 2.0 mm) was operated for 3 min, and the volumes of feed, underflow and overflow were determined. After that,
