The apparatus involves a series of inclined plates upon which mercury reducing bacteria are present, and a subsequent alkaline pH precipitation chambers and an ion exchange chamber.

This is an air-sucking, sterilizing and wastewater treatment method for dental clinic bed. It has an air-sucking and sterilizing device, and a wastewater-treating device below a gargle bench of a dental clinic bed. The air-sucking inlet of the air-sucking and sterilizing device is connected above the bench top to an air-sucking pipe that can be bent to form. At the other end of the air-sucking pipe is an air-sucking mask equipped with a clinical lamp. Utilizing the bendable property of the air-sucking pipe, the dentist can adjust the air-sucking mask with the clinical lamp to an optimum position, to collect germ-carrying flying saliva and volatile chemicals produced in the clinical process, or the flying moisture from the tooth grinding machine in the air-sucking and sterilizing device. Inside the air-exhaust valve is a ion device for purifying purpose to enhance hygienic quality of the entire clinical process, and avoid unnecessary contamination of flying saliva. The wastewater-treating device will clean the patient's mouth and chemical solutions and germ-carrying wastewater, filter and sterilize it thoroughly before discharging it, so the discharged wastewater will not pollute river sources.

The invention discloses oral sewage treatment equipment. The oral sewage treatment equipment comprises an oral sewage treatment box and a power cavity formed in the oral sewage treatment box, whereina power device is arranged in the power cavity and comprises a motor arranged on the outer end surface of the left wall of the power cavity; a transmission cavity is formed above the top wall of the power cavity; and a water storage cavity is formed in the right side of the power cavity. The equipment is simple in structure, simple and convenient to use, capable of realizing automatic filtration,automatic disinfection, automatic drainage, and greatly improved in treatment efficiency of oral sewage from a dental department; meanwhile, mechanical control is achieved during the entire oral sewage treatment, a sewage treatment amount can be accurately controlled, and the situation that sewage treatment cleaning is insufficient or energy is wasted due to the fact that too much or too little sewage is treated is avoided; the equipment is low in cost and can be promoted in small and medium-sized dental oral clinics, and procurement cost is saved for enterprise owners.

The apparatus and method of amalgam waste recovery provides for the effective recovery of amalgam waste, including mercury and other toxic substances, during a dental procedure. The apparatus includes a novel filter that effectively captures waste and a recovery method that provides for the efficient recovery of mercury, gold, and silver waste during dental procedures. The filter includes a cylindrical shape that effective entraps dental waste both along the sides and upon the flat, circular end. The apparatus may be composed of cellulose or paper allowing recovery of mercury vapors and other by-products.

A device for preventing build up and/or reducing biofilm pathogens from medical or dental fluids includes a housing defining a sanitizing chamber. A water conduit may extend through the sanitizing chamber and channel water from a water inlet to a water outlet. A gas inlet may receive pressurized gas and gas outlet may flow the pressurized gas from the inlet to the gas outlet through the sanitizing chamber. A light source emits light into the sanitizing chamber, the emitted light being incident on the water conduit and/or the pressurized gas in the sanitizing chamber and having wavelengths effective for removing biofilm pathogens from the water and/or the pressurized gas to sanitize the water and the pressurized gas. The sanitized water and gas may be used when performing medical or dental procedures. The device may further include a recirculation system for recirculating water from the water outlet to the water inlet.

An amalgam separator for purifying a waste stream that contains a mixture of air and waste liquid. The amalgam separator contains filter media that comprises a sulfur-impregnated carrier and an ion exchange resin, wherein the ion exchange resin is present at a concentration of from about 25 to about 75 weight percent. During its operation, the amalgam separator separates the waste stream into air and waste liquid portions, purifies the waste liquid portion, and then combines the purified waste liquid portion with the air.

The invention discloses a water sterilization system which comprises a filter cartridge and a filter cartridge cover, the filter cartridge cover is detachably arranged on the filter cartridge, a filter element shell is arranged in the filter cartridge, a top water permeable membrane is arranged at the top of the filter element shell, a bottom water permeable membrane is arranged at the bottom of the filter element shell, and a sterilization filter element is arranged in the filter element shell. A water inlet groove and a water outlet groove are formed in the filter cartridge cover, the waterinlet groove is connected with a water inlet pipe, the water outlet groove is connected with a water outlet pipe, a filter shell sealing rubber ring is arranged on the lower side of the end, away fromthe water inlet pipe, of the water inlet groove, and the bottom of the filter shell sealing rubber ring makes close contact with the top permeable membrane; a water inlet is arranged in the center ofthe filter shell sealing rubber ring, a water outlet is formed in the bottom of the bottom permeable membrane. The water sterilization system has the advantages that the occupied area is small, and pipelines do not need to be changed during installation; the system can be mounted and used immediately, can be detected and qualified at any time, and can meet the mounting requirements of various types of dental chairs, full-automatic endoscope cleaning and disinfecting machines, manual endoscope cleaning and disinfecting tanks, various waterways and narrow spaces.

A water purification apparatus includes a water inlet; a medicine mixing device in fluid communication with the water inlet; and a water outlet interconnected to the medicine mixing device and a dental treatment center. The medicine mixing device includes a medicine storage for storing antiseptic solution, a mixing unit interconnected to the water inlet, the water outlet, and the medicine storage, and a controller interconnected to the water inlet and the medicine storage. The controller includes a sensor and a microprocessor. The controller sends the antiseptic solution from the medicine storage to the mixing unit and controls a volume of water flowing from the water inlet to the mixing unit. The microprocessor instructs the controller to control a volume of the antiseptic solution supplied from the medicine storage to the mixing unit based on a signal sensed by the sensor.

The invention discloses a portable sewage treatment device. The device comprises a body; a door plate is embedded into the front surface of the body; one end of the door plate is a fixed end, whereintwo hinges are arranged between the fixed end of the door plate and the body; the other end of the door plate is a free end, wherein a locking mechanism is arranged between the free end of the door plate and the body; through the locking mechanism, the door plate can be opened and closed conveniently, and internal electric appliances and circuits can be checked and maintained conveniently; operation is simple, fixation is easy, the structure is firm, and working efficiency of the device is improved; through the design of a dehumidifier and a plastic box, moisture in the device is convenientlyabsorbed by the dehumidifier; the dehumidifier is conveniently replaced through the plastic box, so that the interior of the device is kept dry all the time, and the service life of the device is prolonged.
