Abstract: A power generation system comprising a first vessel, a second vessel, a pump operably connected to the first vessel and the second vessel, and a turbine manifold assembly operably connected to the first vessel and the second vessel, wherein the pump creates a positive pressure in the first vessel to force a fluid in a first direction through the turbine manifold assembly and into the second vessel to a pre-determined level by a negative pressure in the second vessel, wherein, once the fluid reaches the pre-determined level in the second vessel, the pump creates a positive pressure in the second vessel to force the fluid in an opposing second direction through the turbine manifold assembly and back into the first vessel by a negative pressure in the first vessel to complete a cycle is provided. Furthermore, associated methods and a turbine manifold assembly is also provided.

Abstract: A system is provided to control fluid flow in a wastewater treatment system through wastewater level manipulation. The wastewater treatment system may include a wastewater treatment plant connected to a plurality of pump stations by a main. Each of the plurality of pump stations may include a wet well with a pump therein. The system may include a central server in communication with a sensor to sense a level of wastewater within the wet well. The pump may be automatically moved to an on position when the level of the wastewater in the wet well is at or above a first level and may be automatically moved to an off position when the level of the wastewater in the respective wet well is at or below a pump cutoff level. The central server may systematically manipulate the first level to selectively set the level of wastewater within the wet well.

Abstract: A method of pumping a liquid using at least one operating tank (2), a pneumatic positive pressure displacement pump (1), which is based on the fact that during pumping, inflow valve (4) closure is controlled through the introduction of a control gas into the operating tank (2) positive pressure displacement pump (1) at a pressure lower than the pressure of the compressed actuating gas and from the hydrostatic pressure at the egress of the outflow valve but higher than the hydrostatic pressure on the ingress into the inflow valve (4), which causes the inflow valve (4) to close. A device for pumping liquids comprising at least one operating tank (2) of a positive pressure displacement pump (1), to which leads a control gas conduit (10) with a control valve (11) mounted thereon, which is used to close off the inflow valve (4), and the lower section of the operating tank (2) has a narrow section in the form of a vertical cylinder (16).

Abstract: Reductions in energy consumption and maintenance requirements for operating a wastewater treatment plant are achieved by controlling the operation of pumps at pump stations along a force main in a systematic fashion. The operation of the pumps is controlled to manage the flow of wastewater along the force main to minimize energy consumption, to eliminate sediment, to manage peak pressures encountered by smaller pumps and to avoid septic conditions.

Abstract: Vessels (10, 11, 12 and 13) are associated with an inlet manifold (14) passing to inlets (16), each controlled by a knifegate valve (17). The lower ends of the pots (10) and (12), and pots (11) and (13), pass material through respective outlet knifegate valves (22) to respective first (23) and second (24) delivery lines. The respective knifegate valves (17) and outlet knifegate valves (22) of pots (10) and (11) on the one hand and pots (12) and (13) on the other, are operable by respective common pneumatic actuators (25). Each pot has an ejector assembly (26) having an upper chamber (28), an air injector nozzle (30), and an accelerator tube (31) to create the venturi function. An air cycling valve (32) transitions the upper chamber (28) between a depressurized space and a pressurized space. The accelerator tube (31) exhausts to a delivery line (23 or 24). Ejector assembly (26) air is supplied via air control valve (35).

Abstract: Pumping under the present invention includes movement of material, in a first embodiment fluid and in a second embodiment a piston assembly, between first and second positions including detection of said material at each position. Control circuitry and supporting mechanical and fluid coupling responsive to material position toggles the pump into alternate modes of operation driving the material toward each point. The pump arrangement has fewer moving parts than traditional pumps and enjoys higher reliability for its simplified design.

Abstract: A system for transporting a highly corrosive liquid solely by pressure differential without the need of mechanical pumps for transporting the corrosive liquid. The system includes a source of gas under pressure (78,82) and first and second corrosive liquid reservoirs (22,24) connected in parallel to the source via a valve (80) such that one or the other, but not both, may receive pressurized gas. A valve (20) connects one or the other, but not both concurrently, of the reservoirs to a point of use (10) of the corrosive liquid and is specifically designed for connecting the reservoir receiving the pressurized gas to the point of use. A valve (36) receives corrosive liquid from the point of use and directs the same to one or the other, but not both concurrently, of the reservoirs, and is specifically designed to provide the corrosive liquid to the reservoir not then receiving pressurized gas from the source.
