Publication number: 20220128453Abstract: 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.Type: ApplicationFiled: January 6, 2022Publication date: April 28, 2022Inventors: David F.

Patent number: 10023478Abstract: 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.Type: GrantFiled: January 30, 2018Date of Patent: July 17, 2018Assignee: NCH CorporationInventors: Adrian J.

Publication number: 20170008785Abstract: A system and method of treating water systems with amoebas produced on-site to reduce biological contaminants, such as algae, bacteria and biofilms, without requiring the use of, or reducing the amount of, chemical treatments that produce harmful by-products. The system and method comprise generating an amoeba treatment solution using an on-site biogenerator and discharging the treatment solution in the water system at predetermined discharge intervals. The operating parameters of the biogenerator are monitored and controlled to maintain one or more operating conditions, such as dissolved gas levels, temperature, or pH inside a growth tank within desired ranges. An amount of amoeba starter material sufficient to supply the biogenerator for a prolonged treatment cycle, such as 30 days, is provided and stored in a temperature controlled environment near the biogenerator to maintain the viability of the amoebas prior to generating each dose of treatment solution.Type: ApplicationFiled: July 7, 2016Publication date: January 12, 2017Inventors: Adrian J.

Patent number: 7314544Abstract: A method for the anodic electrochemical synthesis of ammonia gas. The method comprises providing an electrolyte between an anode and a cathode, providing nitrogen and hydrogen gases to the cathode, oxidizing negatively charged nitrogen-containing species and negatively charged hydrogen-containing species present in the electrolyte at the anode to form adsorbed nitrogen species and adsorbed hydrogen species, respectively, and reacting the adsorbed nitrogen species with the adsorbed hydrogen species to form ammonia. Nitrogen and hydrogen gases may be provided through a porous cathode substrate. The negatively charged nitrogen-containing species in the electrolyte may be produced by reducing nitrogen gas at the cathode and/or by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte.Type: GrantFiled: August 25, 2005Date of Patent: January 1, 2008Assignee: Lynntech, Inc.Inventors: Oliver J.

Patent number: 6881308Abstract: A method for electrochemical synthesis of ammonia gas comprising providing an electrolyte between an anode and a cathode, providing hydrogen gas to the anode, oxidizing negatively charged nitrogen-containing species present in the electrolyte at the anode to form an adsorbed nitrogen species, and reacting the hydrogen with the adsorbed nitrogen species to form ammonia. Preferably, the hydrogen gas is provided to the anode by passing the hydrogen gas through a porous anode substrate. It is also preferred to produce the negatively charged nitrogen-containing species in the electrolyte by reducing nitrogen gas at the cathode. However, the negatively charged nitrogen-containing species may also be provided by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte mixture in a sufficient amount to provide some or all of the nitrogen consumed in the production of ammonia.Type: GrantFiled: March 4, 2002Date of Patent: April 19, 2005Assignee: Lynntech, Inc.Inventors: Adrian J.
