ABSTRACT:
A process to reduce or prevent biofouling, by destroying or deactivating microbiological content of feedwater, or other liquid, prior to its entrance into membranes or process equipment, such as heat transfer equipment. The process comprises the use of electrical discharge and/or electric fields to destroy microbes that result in the biofouling of surfaces. By destroying the microbiological content of the water the microbiology no longer is able to create a restricting biofilm upon or within said process equipment.
