Abstract: A filter unit for a conventional suction system of dental equipment is proposed. It consists of a disposable filter and a connecting module fixed to the suction system. The connecting module removably connects the disposable filter to the system, and includes—an inlet pipe passing a water flow and solid contents from the system, —an outlet pipe returning the water flow into the system, —a hole communicating with the inlet pipe, —a pipe projection communicating with the outlet pipe, and—fixing slots. The filter includes—a container collecting the solid contents, —a cover including inlet and outlet holes and provided with fixing projections removably engaged with the fixing slots, and—a lock-fixer rotatably mounted within the cover. It allows for removable connecting the filter to the system, which significantly improves convenience of servicing the system, safety and sanitary protection of dental personnel.

Abstract: A modular system for reducing the total suspended solids of waste, including scum, sludge and water layers, includes a plurality of chambers each being connected in succession by a corresponding one of a plurality of flow pipe segments including an inlet segment, an outlet segment and at least one middle segment, wherein the waste enters the septic tank via the inlet segment and is transferred between each of the plurality of chambers via the at least one middle segment; a corrugated flow pipe in fluid flow communication with the outlet segment; and the corrugated flow pipe being sized and configured for use as a settling zone for removal of a portion of the total suspended solids and wherein an amount of water from the water layer within the chamber adjacent the outlet segment enters the corrugated flow pipe and passes through the outlet segment.

Abstract: A sewage treatment device includes a stirring structure, a filter box, a tank filter, and a detection structure which are connected in sequence. Conveying pipelines are connected to an exterior of the stirring structure to convey sewage to an interior of the stirring structure. First water pumps are connected to the conveying pipelines to provide conveying power. An upper-layer stirrer assembly, a lower-layer stirrer assembly and a rotating shaft configured to install the upper-layer stirrer assembly and the lower-layer stirrer assembly are arranged in the interior of the stirring structure. A lifting driving cylinder drives the upper-layer stirrer assembly and the lower-layer stirrer assembly to move up and down. The upper-layer stirrer assembly includes an engaging block axially engaged with the rotating shaft and stirring blades arranged around the periphery of the engaging block at equal intervals.

Abstract: The present disclosure of a sewage treatment device includes a compression tank that is cylinderically shaped, a stirring structure communicated with the compression tank by a first intermediate pipe, and a detection box communicated with the stirring structure by a second intermediate pipe. A telescopic driving cylinder is arranged on an upper portion of the compression tank and a conveying pipe is connected to a top surface of the compression tank to deliver external sewage to an interior of the compression tank. A diameter of the conveying pipe ranges from 8-15 cm; A filter interlayer is arranged in an interior of the compression tank and the filter interlayer is annular. An end of a driving shaft of the telescopic drive cylinder is connected with a compression body. An outer periphery of the compression body is contacted with an inner wall of the filter interlayer.

Abstract: An apparatus and method is provided for healing and regeneration of live human and animal bodies and influencing interaction and intercommunication at the cellular level. The apparatus can include one or more environmental and/or body sensors. An electrical circuit can also be provided to produce a square or trapezoidal wave that is delivered to a transducer for application, preferably timed at specific frequencies Delta, Theta, Alpha, to Beta, based on information received from the one or more sensors. In certain embodiments, a DC power source can be provided which allows the apparatus to be portable. A wireless communication module can also be provided. An apparatus and method for structuring water is also disclosed.

Abstract: A magnetic filter (10) includes first and second separation chambers (10, 12). The separation chambers (10, 12) each have an inlet and an outlet, and the separation chambers (10, 12) are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement (28) connects both inlets to a single inlet pipe, and an outlet port arrangement (30) connects both outlets to a single outlet pipe.

Abstract: A liquid-liquid contact device includes: an internal casing surrounding an inner chamber for providing countercurrent contact between a light liquid and a heavy liquid; an external casing surrounding the internal casing so as to form an outer chamber around the internal casing; a light liquid introduction tube guiding the light liquid to the inner chamber; and a heavy liquid introduction tube guiding the heavy liquid to the inner chamber. The internal casing has an upper opening and a lower opening which opens at a location below the upper opening. The external casing has a heavy liquid discharge outlet through which the heavy liquid is allowed to be discharged from the outer chamber, and a light liquid discharge outlet which is disposed above the heavy liquid discharge outlet and through which the light liquid is allowed to be discharged from the outer chamber.

Abstract: A pump-storage device includes a tank, a treatment container, and a vacuum pump. The treatment container includes a first chamber in communication with an inlet. The first chamber includes a bottom wall having a first valve intercommunicated with a second chamber. The second chamber includes a bottom wall having a second valve. The treatment container includes a first control valve having a first duct in communication with the first chamber, a second duct in communication with the second chamber, and a third duct in communication with the tank. The treatment container includes an actuation cylinder for actuating an actuation rod to extend or retract. A first valve plate and a second valve plate are mounted on the actuation rod for controlling opening and closing of the first valve and the second valve. The treatment container includes a second control valve in communication with the first chamber and the vacuum pump.
