Hairy roots are genetically transformed roots and highly recommended sources for various secondary metabolites products. Artimisinin is one of them and frequently utilized as pharmaceutical drug for malaria impairment. Hairy roots are fragile tissue and very much sensitive in regarding to culture inside the bioreactor. Designing of bioreactor and optimising the acquired physical and chemical pa...

Abstract Deinked pulp flotation column has been applied in wastepaper recycling. Bubble size in deinked pulp flotation column is very important during the flotation process. In this paper, bubble images of deinked pulp flotation column were first caught by digital camera, and then the bubbles were detected by using a detection algorithm based on sparse and redundant image processing. The result...

in this work, response surface methodology (rsm) and artificial neural network (ann) were used to predict the decolorization efficiency of reactive red 33 (rr 33) by o3/uv process in a bubble column reactor. the effects of four independent variables including time (20-60 min), superficial gas velocity (0.06-0.18 cm/s), initial concentration of dye (50-150 ppm) and ph (3-11) were investigated us...

A wide-ranging review is presented on the most focal aspects of gas-liquid-solid reactors to discuss fresh headways towards understanding slurry bubble column reactors' behavior. In more detail, in this critical review, published works' findings concerning effects solid particles characteristics (size, concentration and density) volumetric mass transfer coefficient, liquid-side gas-liquid inter...
