The invention relates to a testing kit to test dental unit waterlines to meet the CDC water safety monitoring guideline using EPA compliant standards.

The CDC recommends water used in non-surgical procedures to be delivered from dental unit waterlines that follow the Environmental Protection Agency's (EPA) standard for safe drinking, which contain less than or equal to 500 colony forming units of heterotrophic bacteria per milliliter of water (500 CFU/mL).

The goal of the invention is the development of a cost effective in-office test kit to monitor the safety of dental unit waterlines by following suggested EPA protocol of counting bacteria colonies after bacteria has gone through an incubation period.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump. The ozone and the oxygen are turned into ultra-fine bubbles via cavitation action within the pump, facilitating the dissolution of the oxygen and ozone within the water. The water mixed with the oxygen and the ozone is subsequently supplied to a line atomizer, where the dissolution of the ozone within the mixture is completed. The combined use of the cavitation pump and the line atomizer can lead to a substantially complete dissolution of the supplied ozone within water that needs to be disinfected, allowing to easily achieve the concentration of ozone necessary for water disinfection. Due to this efficiency, the system and method described are highly scalable and suitable for water purification at water purification plants of various sizes.

A beverage maker is provided having a filtered water system for processing pressurized potable water, a flavor infusion system, and a beverage discharge. Purified filtered water is thereby directed alternately directly to a beverage discharge, or through the flavor infusion system to the beverage discharge. An additional water carbonation system may be incorporated between the filtered water and the flavor infusion system such that carbonated, filtered water may be directed alternately directly to a beverage discharge, or through the flavor infusion system to the beverage discharge. The beverage maker is capable of alternately dispensing filtered, flavored, carbonated or noncarbonated water based beverages.

A diffusiophoretic water filter has a monitor for monitoring for leaks, blockages or efficiency. Methods are also provided.

A coolant liquid processing system includes: a filtration device for filtering a coolant liquid containing sludge; and a detector that detects particles in a treatment liquid filtered by the filtration device.

A method and apparatus for treating water that results in water having a hydrogen bond angle of greater than 110, preferably in a range of about 113 to about 114. The method includes: channeling the water into a receptacle; devolatilizing and deaerating the water in the receptacle by using a condensing channel immersed in the water contained in the receptacle; channeling a portion of the water from the receptacle to a boiler via a feeder channel; heating the water in the boiler to generate steam; providing ozone to the steam in the boiler; and channeling the steam into the condensing channel. The apparatus includes a closed receptacle, a condensing channel housed in the receptacle, and a boiler in fluid communication with the receptacle. The boiler includes a boiler housing, an ozone generator and at least one heater having a total power of about 1500 watts.

A system for generating sterile water is provided, including: a liquid holding container having thereon a container outlet; a filtration device including therein a low-pressure-differential pathogen filtration portion, wherein the filtration device has a filtration inlet and a filtration outlet; and a gas tube; wherein the container outlet is connected to the filtration inlet; wherein the filtration inlet has a gas hole with one end connected to the gas hole and the other end having a buoy; wherein the sterile water is substantially pathogen-free.

Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.
