The OP paper's "Materials and methods" section references an earlier study of theirs on CHC: "Energy efficient inactivation of Saccharomyces cerevisiae via controlled hydrodynamic cavitation" [1].
From the OP paper: "A Venturi tube, with the same geometry used in a previous study (Albanese et
al., 2015), is used as the cavitation reactor and preferred over an orifice plate since it
was observed that orifices are quickly obstructed by the circulating solid particles. "
The referenced paper gives specifications for the Venturi tube:
"The cavitation reactors used for the experiments were
an orifice plate equipped with 156 holes (each having an
internal diameter 2 mm) and a Venturi tube (Fig. 2A and
B). Both are upscale models of effective configurations
used in laboratory scale experiments by researchers in
India [23, 28]. The orifice plate total opening was
490 mm2 (6.55% of the main pipe’s inner section). The
corresponding value for the opening of the Venturi tube’s
nozzle was 452 mm2 (6.05% of the pipe’s section)."
Might not be too difficult to obtain such a device.
