The substance is directed to the inlet of the volute or cyclone head and irradiated with one or more wave energies produced by the first and second wave energy sources as the substance passes through the device.

Band-pass filters for guiding or controlling crystal polymorphism in oil are provided. Band-pass filters convert a passive energy source to a spectral energy pattern tuned to be resonant with different types of molecular oscillations pertinent to oil. Tuned energy patterns convert problematic insoluble crystals to more thermodynamically stable and soluble crystals. Methods include use of the band-pass filter in crude oil recovery and design of band-pass filter parameters for optimal use on a particular oil recovery facility. Band-pass filters also lower the interfacial tension of oil when present with water, which are also provided, as are methods for enhanced recovery of oil from depleted oil fields.

A hybrid twin process uses an independent mechanical destructive process and an illumination process to change of state of weed seeds to having reduced germination viability by illuminating a seed with at least one of 2 J/cm.sup.2 cumulative illumination energy, and 0.2 W/cm.sup.2 irradiance, but no more than 7 W/cm.sup.2 average irradiance, of at least one of an Indigo Region Illumination Distribution (IRID), and infrared radiation that is substantially Medium Wavelength Infrared (MWIR) radiation, preferably 2-8 microns. The process can be incorporated into a harvester combine to convert a tailings flow prior to discharge on an agricultural field. For the mechanical destructive process, high required applied energy, noise, wear, and difficulty treating impact-resistant seeds are avoided by modifying a driven load flow via increased capability of exposure to illumination and underdriving the mechanical destructive process. This can include randomization, rarefaction and enhanced circulation.
