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. 1: http://onlinelibrary.wiley.com/store/10.1002/ese3.62/asset/ese362.pdf;jsessionid=0BDB4DD2578B1C24C7FE98427401486F.f02t01?v=1&t=itkzm3v1&s=df66244835b7c46c8e80fd2b07ad00e5a140d505 http://onlinelibrary.wiley.com/store/10.1002/ese3.62/asset/e...
