摘要： A system and method for treating flowing water systems with a plasma discharge to remove or control growth of microbiological species. Components of the water system are protected from being damaged by excess energy from the electrohydraulic treatment. Ozone gas generated by a high voltage generator that powers the plasma discharge is recycled to further treat the water. A gas infusion system may be used to create fine bubbles of ozone, air, or other gases in the water being treated to aid in plasma generation, particularly when the conductivity of the water is high. An electrode mounting assembly maintains a high voltage electrode and ground electrode at a fixed distance from each other to optimize plasma generation. An open support structure for the high voltage generator circuit physically separates spark gap electrodes and resists metal deposits that may disrupt discharge of a high voltage pulse to create the plasma.

摘要： A system and method for treating flowing water systems with a plasma discharge to remove or control growth of microbiological species. The system and method protect other components of the water system from being damaged by excess energy from the electrohydraulic treatment. The system and method also recycle ozone gas generated by a high voltage generator that powers the plasma discharge to further treat the water. A gas infusion system upstream of or inside a plasma reaction chamber may be used to create fine bubbles of ozone, air, or other gases in the water being treated to aid in plasma generation.

摘要： A system and method for monitoring or detecting a level of biofilm growth in a fluid system and controlling operating parameters of the fluid system based a measured level of growth. The monitoring system and method comprises a dye injection system for periodically injecting dye into a portion of fluid from the fluid system, passing the portion of fluid though a narrow lumen tube to achieve laminar flow and using a light source and optical sensor to detect a transmission or emission indicating a level of biofilm growth in the tube corresponding to a level of growth on components in the fluid system. Information based upon the measurements or calculations made by the monitoring system may be used to manually or automatically alter various operating parameters to control the fluid system and aid in maintaining stable operation of the fluid system within preferred specifications.

摘要： A composition and method for reducing odors and cleaning packing media and other components in a wet air scrubber using nonionic surfactants, amphoteric surfactants, and a source of humic acid. Preferred nonionic surfactants include regular and low foam nonionic surfactants. The source of humic acid is preferably organic peat humus. The treatment composition is added to water in the wet scrubber at a concentration of 50-1000 ppm. The treatment composition is a premixed composition in a single container, making it unnecessary to separately add ingredients to the water. The treatment composition is effective at reducing odors by at least 50% compared to no treatment. The treatment composition is also effective at significantly reducing foam levels, making it unnecessary to add a separate defoamer to the water being treated. The treatment composition does not need to use defoamers, enzymes, oxidizers, chlorine compounds, or strong acids to be effective.
