The present invention is a modified apparatus for wastewater recycling including a toilet tank device, a water amount control assembly, and a three-way pipe. The toilet tank device includes a filtering space provided with a filtering apparatus and a water level sensing apparatus and a device area provided with a pressurizing device at least one filter, and a transfer pipe. The water amount control assembly includes a driving apparatus, a cleaning pipe group, and a wastewater transfer pipe group. When clean water is transferred to clean the filter, the clean water can be transferred through a combination of the cleaning pipe group and the pressurizing device with a water amount controlled by the driving apparatus, and wastewater passing through the filtering apparatus can be transferred through a combination of the wastewater transfer pipe group and the pressurizing device with a water output amount controlled by the driving apparatus.

A fuel tank assembly for an electrical generator constructed with a double walled tank with side walls, a front wall mounted to the side walls, a rear wall mounted to the side walls, a bottom wall mounted to the side, front and rear walls and a top wall mounted to the side, front and rear walls. The side walls, front and rear wall and bottom wall are constructed with a spaced outer wall and an inner wall defining an enclosed central chamber adapted to receive diesel fuel; the inner bottom wall defining at least two angled sections extending inward into the central chamber toward the outer bottom wall. A skid assembly is mounted to the outer bottom wall to provide support for the fuel tank. A filtration assembly is mounted to the skid assembly and communicates with a central chamber of the tank and a microprocessor is mounted to the fuel tank, the microprocessor being connected to the sensors and the filtration assembly to receive data from the sensors and filtration assembly and transmit the data to a user.

A water treatment filter backwash process control system, comprising a control system that receives filter level data and filter backwash turbidity data. The control system having a filter level set point, wherein the filter level set point corresponds to a desired filter media bed expansion. The control system having a filter backwash turbidity set point, wherein the control system controls the filter backwash process by, while monitoring the filter backwash turbidity, sending one or more output signals that are used to control a backwash inlet liquid flow in order to maintain a desired media bed expansion, and stop the backwash inlet liquid flow when the filter backwash turbidity set point is reached.

Systems and methods to remotely drain a filter assembly includes a filter, an intelligent solenoid coupled to the filter, a controller communicatively coupled to the intelligent solenoid, the controller configured to: determine, via the filter management circuit, a filter state based, at least in part, on the determination of the fluid amount exceeding the predetermined threshold value, and a remote user device communicatively coupled to the intelligent solenoid, the remote user device configured to: connect, via a network configured for wireless connectivity, to the intelligent solenoid coupled to the filter, receive, from the intelligent solenoid, information corresponding to a filter state indicative of the fluid amount corresponding to the filter assembly, and transmit instructions to the intelligent solenoid configured to actuate the intelligent solenoid to thereby cause a release of fluid responsive to the filter state and the transmitted instructions.

A water treatment filter backwash process control system, comprising a control system that receives filter level data and filter backwash turbidity data. The control system having a filter level set point, wherein the filter level set point corresponds to a desired filter media bed expansion. The control system having a filter backwash turbidity set point, wherein the control system controls the filter backwash process by, while monitoring the filter backwash turbidity, sending one or more output signals that are used to control a backwash inlet liquid flow in order to maintain a desired media bed expansion, and stop the backwash inlet liquid flow when the filter backwash turbidity set point is reached.

A method of filtrating liquid, the method comprising conducting a liquid through a filtering element, through an outlet line downstream of the filtering element and to a collection volume downstream of the outlet line; controlling a differential pressure of the liquid over the filtering element; and controlling a passing time of a filter flow of the liquid through the filtering element in conjunction with the differential pressure; wherein the control of the differential pressure and the passing time comprises controlling a collection volume liquid flow of the liquid out from the collection volume; and controlling a gas flow out from the collection volume. A filtration apparatus for filtrating liquid is also provided.

A filtration arrangement for a filtration apparatus for filtrating liquid, the filtration arrangement comprising a filtration vessel; a continuous filtering element for removing particles from liquid passing therethrough, the filtering element being arranged to move along a path into the filtration vessel and out from the filtration vessel; and two wheels sealingly engaging the filtering element on opposite sides thereof inside the filtration vessel, where each of the two wheels is rotatable relative to the filtration vessel along with movement of the filtering element. A filtration arrangement comprising a fluid ejecting device, and a filtration apparatus are also provided.

An apparatus including a screen capable of separating solids from a liquid-solid mixture and a first probe disposed beneath the screen. The first probe is provided to determine a position of a beach between the liquid-solid mixture and separated solids. The apparatus may measure a property of a local volume of a probe disposed beneath a first separator deck. The probe may then send a first signal to database. Based on the signal a location of a beach may be determined.

Fluid filtration systems and methods for servicing thereof are disclosed. The fluid filtration system includes a filter cartridge, a fluid transfer pump, and a valve assembly that can be selectively operated and positioned to achieve a normal filtration mode of operation, a fuel drain mode of operation, and a water drain mode of operation. In the normal mode, the filter cartridge is in an installed position, the pump is rotated in a first direction, and the valve is placed in a first position. In the fuel drain mode, the filter cartridge is in a service position, the pump is rotated in a second direction, and the valve is placed in a second position. In the water drain mode, the filter cartridge is in an installed position, the pump is rotated in the second direction, and the valve is placed in the first position.

A flushing system comprises: an oil tank for storing oil; a pipe system connected to the oil tank by means of a pipe to circulate the oil by means of the operation of a main pump; a microbubble generator connected to at least any one of the oil tank and the pipe system to generate the microbubbles in the pipe along which the oil flows and in the oil tank and thus to inject the microbubbles into the pipe; a water remover connected to the oil tank to remove the microbubbles and water from the oil; and a particle remover connected to the oil tank to remove microbubbles and foreign substances from the oil by means of electric precipitation.
