Systems and methods for processing one or more waste fluids by measuring one or more properties of a waste fluid and adjusting the flow and/or flowability of the waste fluid based on the measurement are disclosed. The one or more properties of the waste fluid can include a viscosity of the waste fluid, a pressure of the waste fluid, and/or or a difference in pressure of the waste fluid. Adjusting the flow and/or flowability of the waste fluid can include adjusting the one or more properties of the waste fluid and/or affecting the direction of flow of the waste fluid in a manner which changes the destination of the waste fluid.

Provided in one implementation is a method that includes introducing a volume of raw material into a chamber of a cavitation machine. The raw material can include a mixture comprising a powder and a solvent. The powder can have a first average particle size in the raw material. The method includes applying a hydrodynamic cavitation process to the raw material to produce a product material. The powder can have a second average particle size, smaller than the first average particle size, in the product material. The method includes causing the product material to exit the cavitation chamber and drying the product material to remove the solvent. Apparatus employed to apply the method are also provided.

Provided in one embodiment is a method of making paste for solar cells. The method can include forcing silver through a feed tube coupled to a hydrodynamic cavitation chamber using an air-driven piston. The method can include subjecting the silver to hydrodynamic cavitation in the hydrodynamic cavitation chamber by using a hydraulic pump to pass the silver sequentially through a primary orifice, a secondary orifice, and a final orifice within the hydrodynamic cavitation chamber to produce the paste for the solar cells. The silver can include up to three unique silver powders having a total particle size distribution from 0.1 microns to 10 microns. A first silver powder can have a first average particle size of 1.5 um, a second silver powder having a second average particle size of 0.5 um, and a third silver powder having a third average particle size of 0.2 um.
