An automated system and method is provided for cultivating bacteria in a fluid medium and thereafter selectively discharging the fluid medium, wherein an initial supply of the selected strain or strains of bacteria is combined with nutrients and water in a biogenerator in the presence of air to promote mixing and bacterial cultivation. The system and method utilize a vortex created by recirculation of the fluid medium to achieve aeration and mixing without substantial foaming. The system and method are particularly useful for supplying bacteria to control grease accumulation in restaurant grease traps. The system and method use a biogeneration chamber which has a cylindrical sidewall and surface on the inner side. Further, the chamber has a top and a conical bottom. The top has inlet ports and a vent port.

A biomass generator useful for continuously growing and withdrawing bacteria to be used in a desired beneficial application, the generator having a bacteria growth chamber; water and nutrient inlet ports; upper and lower outlet ports; a recirculating pump withdrawing and reintroducing fluid to establish a vortex in the growth chamber while controlling foaming and pump cavitation; a low pressure air inlet line discharging air inside the growth chamber above the vortex; a fluid discharge line receiving bacteria-containing fluid from the upper outlet port of the growth chamber; a flush line discharging wash water into the fluid discharge line; and an electrical controller cooperating with solenoid-operated valves and a feeder mechanism to periodically introduce water and nutrients into the chamber, thereby simultaneously causing bacteria-containing fluid to be discharged from the growth chamber through the upper outlet port. A method for growing bacteria using the subject apparatus is also disclosed.

A recirculating parts washer is disclosed that features a vertically mounted base and a sink and lid rotatably connected to the base. The recirculating parts washer features a cleaning fluid supply container which is separate from the sink but connected to it via a supply line and a drain line. Cleaning fluid is circulated to the sink via the supply line by means of a submersible pump submerged within the cleaning fluid inside the cleaning fluid supply container. Cleaning fluid returns to the supply container via the drain line, thus enabling the cleaning fluid to be reused over and over again until it is exhausted. By having the sink and lid rotatably mounted to the base of the recirculating parts washer, the bulk of the assembly can be conveniently pivoted upwards and back against the wall when not in use. The recirculating parts washer also features a direct current power supply assembly.

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.
