Abstract: A process for internally cooling an inline compressor comprises the steps of providing a compression chamber between an outer cylinder and an intermediate cylinder and a drive chamber between the intermediate cylinder and a piston; admitting gas into the compression chamber; pumping drive fluid through the piston into the drive chamber to extend the intermediate cylinder and compress the compression chamber and the gas in the compression chamber; allowing heat from the compressed gas to transfer to the drive fluid; allowing the compressed gas to exit the compression chamber; allowing the withdrawal of the drive fluid from the drive chamber; passing the withdrawn drive fluid through a heat exchanger to cool the drive fluid for reuse in extending the intermediate cylinder.

Abstract: A hydraulically operated compressor has a fixed piston and a fixed compression or outer cylinder. A drive or intermediate cylinder is located between the piston and outer cylinder. A compression chamber is formed between the drive cylinder and the outer cylinder. Drive fluid is pumped into and released from an interior chamber in the drive cylinder to reciprocate the drive cylinder. The drive fluid also provides cooling to the interior of the compressor.

Abstract: A wastewater treatment system comprises a fluid conveyance, one or more filtration vessels, one-way valves, and a backwash collection conduits. The filtration vessels each have a vessel inlet and a vessel outlet. Filtration media is positioned between the respective vessel inlet and the respective vessel outlet. Each respective vessel inlet communicates with the fluid conveyance. Each one-way valve is located at the inlet of the respective filtration vessel to regulate a flow of fluid from the fluid conveyance into the respective filtration vessel and to prevent the fluid from exiting the respective filtration vessels through the one-way valves. Each backwash collection conduit communicates with each filtration vessel by a drain conduit, the drain conduit having an outlet that is above a top of a fluid volume in the backwash collection conduit so as to provide an air gap.

Abstract: A compact, portable system and process separates dissolved and suspended solids from water containing high levels of those solids. Gas flotation is used with and oxidant as an initial stage. The resulting foam is dewatered in a fluid conveyance, with the gas being recycled to the flotation column, the foam sent to a holding tank and the water passed through one of a number of filtration vessels having granular filter media. As at least one filtration vessel is kept in operation filtering, another filtration vessel can be backwashed when the flow therethrough is diminished of the fluid level inside rises. Treated water is used for backwashing and provided to a collection conduit.
