  • Patent number: 11141035
    Abstract: A roller mop capable of self-cleaning, comprising a pull rod (41), a mop head component (1), and a cleaning basin capable of holding the mop head component (1). The pull rod (41) is grasped by a person to operate; a motor (15) in the mop head component (1) drives a roller (10) to clean the ground; after the mopping is ended, the mop head component (1) can be put in the cleaning basin for charging and washing with water. The roller mop provided with a trash bin (17) can receive a number of small trashes; labor intensity is reduced due to the driving of the motor (15); the mop can perform continuous operation, and thus high cleaning efficiency is achieved; moreover, the mop has a self-cleaning effect, and is easy to use.

    Abstract: A process involves heating waste grease in a first separation chamber to separate it into a primary oil, aqueous, and solid phase and decanted the primary oil phase by flowing it upwardly and over a liquid impermeable barrier and into a second separation chamber. Components of the primary oil phase are separated into a secondary oil, aqueous, and solid phase. The secondary oil phase is decanted by flowing it upwardly and over a different liquid impermeable barrier and into a heating chamber. In the heating chamber, the secondary oil phase is heated to a temperature sufficient to separate components of the secondary oil phase into a tertiary oil phase, aqueous phase, and solid phase. The tertiary oil phase comprising brown grease is extracted. The remaining tertiary aqueous and solid phases in the heating chamber may be heated again to produce a tertiary oil phase comprising additional brown grease.

  • Patent number: 10150684
    Abstract: A wastewater treatment system and method are provided for preventing or reducing ammonia rebound during periods of warming weather. The system may be operated in first and second modes of operation. During the first mode of operation, wastewater may pass directly from a reactor to a partial mix cell and then to a polishing cell. During the second mode of operation, which typically occurs during a springtime warmup period, wastewater is retained within the partial mix cell until sludge and biosolids therein are substantially digested, while wastewater exiting the reactor is temporarily directed to the polishing cell, thereby bypassing the partial mix cell. Upon digestion and stabilization of the sludge and biosolids in the partial mix cell, the system may return to the first mode of operation. Sludge and biosolids may optionally be removed from the reactor during the first and second modes of operation.

  • Publication number: 20150090659
    Abstract: An upflow continuous backwash deep bed sand filter (UCBF) having a recycle line for returning carbonaceous denitrifying bacteria attached to biomass to the influent of the UCBF. The recycle line returns the biomass to the treatment process at a location upstream of the upflow continuous backwash filter. Further, a liquid level control unit is provided that reduces fluctuations and significant drop in the liquid level upstream of the upflow continuous backwash filter, thereby avoiding or minimizing flow turbulences, air induction, and undesirable wastewater aeration resulting in the need to dose excessive carbon source to remove dissolved oxygen in the aerated wastewater.

  • Publication number: 20150083648
    Abstract: A method system for processing interface emulsion, water, and solids contained within a separator vessel that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell. The cell, which is preferably a vertical induced gas flotation cell, separates the oil and water contained in the interface emulsion and discharges recovered oil from an upper portion of the cell and treated water from a bottom portion of the cell. The recovered oil and treated water may be further processed and recycled to the vessel or sent elsewhere. The treated water may also be recycled to the cell or sent to a process sewer. Fuel gas residing in an upper portion of the cell may be cooled and passed through a splitter. All the steps of the system comprise a closed system with no air emissions.

  • Patent number: 8945377
    Abstract: An installation-free water purifying device comprises a raw/waste water common container and a filtering body. This raw/waste water common container is separated by a partition into an upper space and a lower space. The filtering body has a storing space, a purified water container, a filtering unit, and a flowing controller. Raw water is initially stored in the raw/waste water common container 10. Next, raw water in the upper space is pumped to the filtering unit for water filtering and then guided as purified water into the purified water container. Waste water generated from the filtering unit is guided into the vertical guiding portion so as to push the raw water in the lower space moving upward. In which, it does not require any complicated installing work. Waste water can be recycled. The user can start to use it quickly by an electric plug.

  • Patent number: 8894852
    Abstract: A system for producing and supplying a coolant to a filtration sub-system, and for reconditioning and recombining a return flow of used coolant. A main reservoir is in two way communication with the filtration sub-system via a clean coolant outlet and a dirty coolant return. An inlet feeds an untreated water supply to a de-ionization canister. A mixing valve in communication with the inlet recombines a remaining untreated portion of the water supply with the de-ionized portion. A mixing pump intermixes the water supply with a chemical concentrate to produce a coolant delivered to a main reservoir. A volume of coolant is drawn through an outlet from the reservoir and communicates the coolant to a particle filter, a chiller, and prior to outputting to the filtration sub-systems. The used return coolant is filtered and reintroduced to the main reservoir.

  • Patent number: 8889007
    Abstract: The present invention is a wastewater treatment system utilizing a recirculating filter system comprising sand, gravel, or synthetic media. Septic effluent is continuously, or approximately continuously, dosed under pressure to the treatment media through pressure compensating drip irrigation emitters. The system comprises a commonly known septic tank and recirculation tank. Septic tank effluent is collected in the recirculation tank, from which it is continually dosed by means of a pump to the top of the treatment media of the recirculating filter through pressure compensating drip emitters. Continuous dosing of diluted residential septic tank effluent through drip irrigation emitters provides a slow consistent application of liquid rich in organic material and pathogens over the treatment media. The treated effluent is then recirculated if water is low or went to final disposal.
