The present inventive concept relates to a water recycling device comprising: an outlet configured to output treated water; a drain for collecting used water output from said outlet; a return/evacuation path in liquid communication with said drain, wherein said return/evacuation path comprises an inlet for receiving water collected by said drain; a return path in liquid communication with said return/evacuation path; a treatment path in liquid communication with said return path and said outlet; an external water path in liquid communication with said treatment path, said external water path being connected to an external water outlet; a valve arrangement configured to accept as inputs used water from said return path and/or external water from said external water path, said valve arrangement being placed between said return path and said treatment path, said valve arrangement being configured to direct said inputs to said treatment path, said valve arrangement being configured to mix said external water with said used water from said return path; a circulation pump for providing a flow in said water recycling device; and a water treatment arrangement placed downstream to said valve arrangement.

Embodiments of the present disclosure generally provide a grey water interface valve liquid level sensor system. The liquid level sensor system may deliver information about the water level and the water movement that occurs in a water reservoir. A control unit may then activate a valve to open so that the water can be removed via vacuum.

A toilet tank structure is formed by a primary-secondary water tank set, a tap water inlet control valve, a secondary water tank inlet control valve and a flush control module, and the tap water inlet control valve, the secondary water tank inlet control valve and the flush control module are provided for controlling the flushing and water supply to minimize the waste of water resources effectively, so as to achieve the effects of saving water and improving functionality.

The present invention relates to water disposable system comprised of a connecting member having a first side of the connecting member which is connected to at least one unwanted water source which feeds unwanted water to the toilet tank via gravity and further comprises at least one valve to control the flow of unwanted water. The water tank of the toilet is connected to a second side of the connecting member to receive unwanted water and is further enabled to receive fresh water from a fresh water pipe. The water tank comprises a strainer and a standpipe to refill the toilet bowl and the tank simultaneously whilst preventing debris from clogging the small ports within the rim of the toilet bowl. A flushing lever and a second end of the lever is coupled with a rubber flap via a chain with a small float attached at the minimum water line. The purpose of the rubber flap is to allow sufficient water into the bowl in order to flush waste, and the small float attached to the chain is to maintain tension on the chain keeping the flap open when only a small amount of water is available and to allow efficient flushing. Fresh water is maintained at a minimum in the tank by the use of two floats in communication with respective levers to allow fresh water to enter the toilet tank up to a preset volume by water level within the tank. The first float is situated at a low height within the tank to maintain the minimum volume of water required to flush waste. The second float is situated at a height to maintain the maximum volume of water required to flush waste. The operation of the second float can be suspended, allowing empty volume in the toilet tank to be filled by unwanted or gray-water as it becomes available from the attached sources. Further, a button, wherein a first end of the button is enabled to be actuated by the user to flush the fresh water from the water tank and a second end of the button is coupled with a second float, wherein the second float does not allow the intake of the fresh water from the fresh water pipe until the button is actuated by the user.

In a ball tap 1, a valving element 3 includes a valve part 10 provided with a contact projection part 9 that can come into close contact with a valve seat 7 when the valving element 3 is closed, and a flange part 11 having a circular ring shape in plan view which continues downward from the rim of the valve part 10 and is slidable like a piston in the secondary side flow passage 5, and the left and right half circumferences of the upper surface of the flange part 11 have bilaterally symmetrical shapes curved downward in arch shapes, and the left and right lower limit portions of the upper surface of the flange part are set so as to be positioned at the same heights as those of the lower end edges of drainage ports 8.

Disclosed is a cascade water recycling intelligent system for shale gas exploitation, comprising a cascade water recycling system, wherein a data output end of the cascade water recycling system is connected with a data input end of an information system, a data output end of the information system is connected with a data input end of a decision making system, and a data output end of the decision making system is connected with a regulator; the cascade water recycling system comprises at least one time of water quantity judgment, a current exploiting intensity of shale gas is continued under a condition that the water quantity does not exceed a water safety threshold; and monitoring data is transferred to the information system under a condition that the water quantity exceeds the water safety threshold; the information system is further used for transferring the collected data to the decision making system.

The present invention relates to a heat recovery system, of a part of the energy spent in the preparation of waste water, e.g. water from baths or kitchens, energy that is usually lost when the water is drained into the sewer. This energy can be recovered and reused to heat water that is readily used, for example in the shower, or can be stored in a water heater. This system is designed in such a way that, together with any tub or shower base, constitutes a heat recovery shower base or a heat recovery bath, for example. The energy recovery system is composed, preferably, by a coil generally made of copper inside a PVC pipe that has at one end a throttle plate also made of PVC, a filter for the protection of the system against impurities, turbulence fins, and an external casing. The system has a compact structure which benefits its rapid adaptation.

A wash water reclaim system comprising a platform, the platform comprising a left peripheral edge and a right peripheral edge; a separation chamber, the separation chamber approximately located at the center of the platform; a recycled water storage chamber, the recycled water storage chamber located at either the left peripheral edge or the right peripheral edge of the platform; at least one pipe, the at least one pipe connecting the separation chamber to the recycled water storage chamber; at least one loading deck; the at least one loading deck located between the separation chamber and the recycled water storage chamber, the at least one loading deck angled downward toward the separation chamber; and at least one grating, the at least one grating covering at least a portion of the separation chamber and/or at least a portion of the recycled water storage chamber.
