Abstract: Microfluidic devices for sterilizing fluids using pulsed electric fields are disclosed. In some embodiments, a device may include first and second electrode layers and a spacer layer positioned between the electrode layers. The spacer layer may define one or more fluid channels extending between the electrode layers. A power supply may be coupled to the electrode layers and configured to supply voltage pulses to the electrode layers to generate electric field pulses within the fluid channels. In some embodiments, the electrode layers may be textured such that the electric fields generated in the fluid channels are non-uniform.

Abstract: A self-contained cleaning system using a truck mounted cleaning unit. The cleaning unit has a dual water tank system which is used to recirculate water through a propane hot water unit until the desired water temperature is obtained. The dual water tanks also permit the operator to bring his own supply of water to the job site. A dual pressure water unloading system allows quick switching from high to low water pressures while quick disconnects on the unloading system permit rapid removal for maintenance and/or replacement of the dual water pressure regulators used. The cleaning system is totally self-contained and may be operated without using the utilities of the customer.
