A hydrogen gas dryer or system for drying or removing water from hydrogen gas for use in hydrogen-cooled generators includes a drying tower or column comprising a housing, a heater, a desiccant, and a controller. The system is configurable and operable for regeneration of the saturated column, with activation of the heater to cause water retained in the saturated desiccant to turn into steam such as steam and exit on its own via the vent. A supply of generally dry hydrogen is used to purge the remaining vaporized water from the isolated substantially dry regenerated desiccant.

Wattmeter circuit for operating a grinder pump assembly to inhibit operating under run dry or blocked conditions
A method for operating a grinder pump station and inhibiting the likelihood of operation of a grinder pump assembly under at least one of a run dry condition and a blocked condition includes providing a wattmeter circuit operably connected to the grinder pump assembly and measuring real power using the wattmeter circuit during operation of the grinder pump assembly to process sewage received in a tank and discharge the processed sewage from the tank. The grinder pump assembly is automatically turned off based on the real power (e.g., average value of the product of instantaneous values of voltage and current over time) measured by the wattmeter circuit due to the at least one of a run dry condition and a blocked condition.
A cutting wheel for a grinder pump includes in one embodiment a monolithic disc-shaped base portion having a bottom surface having a plurality of integrally formed spaced-apart, downwardly-depending cutting elements disposed adjacent the peripheral edge of the disc-shaped based portion. In another embodiment, a cutting wheel for a grinder pump includes a monolithic disc-shaped base portion having a bottom surface having a plurality of integrally formed spaced-apart, downwardly-depending cutting elements disposed adjacent the peripheral edge of the disc-shaped based portion, and a plurality of integrally formed downwardly-depending paddle elements spaced-apart from the cutting elements.
A pump assembly supportable in a tank having an opening includes a pump such as a grinder pump and a cover attachable to the pump. The cover has a peripherally-extending portion extending outwardly from the pump and the peripherally-extending portion is sized to rest on a first surface of the portion of the tank defining the opening. A quick-release latching mechanism may include a plurality of members such as arms or pawls which are movable generally radially between a retracted position wherein the outer ends of the plurality of members are disposed inwardly of the peripherally-extending portion of the cover allowing the pump assembly to be lowered into the opening in the tank, and an extended position wherein the outer ends of a plurality of members are positionable against a second opposite side of the portion of the tank defining the opening to compress the portion of the tank forming the opening between the cover and the plurality of members.
A method for operating a grinder pump station (100) and inhibiting the likelihood of operation of a grinder pump assembly (130) under at least one of a run dry condition and a blocked condition includes providing a wattmeter circuit (510, 610) operably connected to the grinder pump assembly and measuring real power using the wattmeter circuit during operation of the grinder pump assembly to process sewage received in a tank and discharge the processed sewage from the tank. The grinder pump assembly is automatically turned off based on the real power (e.g., average value of the product of instantaneous values of voltage and current over time) measured by the wattmeter circuit due to the at least one of a run dry condition and a blocked condition.
