A method for eliminating bubbles from a liquid dispensing system includes flowing a liquid containing bubbles into a liquid inlet of a tank from a filter to substantially fill the tank, wherein substantially all bubbles accumulate in an upper portion of the tank having a lateral dimension greater than a lateral dimension of a lower portion of the tank, and flowing the liquid into the tank comprises flowing the liquid through an inlet pipe extending at an acute angle relative to a horizontally-oriented axis of the tank. The method further includes flowing a liquid substantially free of bubbles out of the tank via a liquid outlet at the lower portion of the tank for dispensing to a substrate.

To provide a gas-liquid separator of a water electrolysis system, comprising: a liquid feeding atomizer and a gas-liquid separation chamber, wherein the liquid feeding atomizer includes a liquid feeding pressurized tube; and an atomizing spray head, in which the atomizing spray head converts a gas-liquid mixed liquor after pressurized by the liquid feeding pressurized tube into a mist droplet gas-liquid mixture. The gas-liquid separation chamber comprises a spiral flowing way, and the spiral flowing way extends the time that the mist droplet gas-liquid mixture spraying into the gas-liquid separation chamber flows downwards to the bottom of the gas-liquid separation chamber; an ultrasonic oscillation mechanism; a stirrer; an internal reservoir; and a filter mechanism, which performs the gas-liquid separation for unbroken bubbles in the mist droplet gas-liquid mixture through the pore difference.

Disclosed is a multi-stage sedimentation rake-free thickening device. The device includes a central tank. A diversion sedimentation zone is arranged on the outside of the center tank. The diversion sedimentation zone includes an annular diversion sedimentation screen and a concentrated magnetic shower. The annular diversion sedimentation screen includes an annular groove spirally arranged around a central groove body. The annular groove is sequentially arranged with second spoiler baffles along the length direction. The lower bottom plate of the annular groove is also provided with second underflow discharge port. Multiple second inclined plate diversion discharge pipe is arranged under the corresponding second underflow discharge ports. The outlets of all the second inclined plate guide discharge pipes are collected to the second underflow discharge pipe, and the settled water is discharged from the second overflow discharge pipe arranged at the end of the annular groove.

The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing an oil phase from an oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is combined with surfactant in appropriate ratios to facilitate oil removal for water purification in any of a number of commercial, environmental and industrial applications.

An agitation/defoaming device is provided, which can independently control revolving and rotational motion and can change a rotational direction relative to a revolving direction without a two-system rotary drive. The apparatus includes a rotary driving source, a braking device for rotary motions; first and second rotors revolved around revolving shaft, and first and second rotational bodies and container holders pivotally supported by the first rotor. A braking force is applied to the second rotor revolving along with the first rotor, generating a rotational motion, which is transmitted to either the first or second rotational body according to the revolving direction of the first rotor. The rotational motion is then transmitted from the first or second rotational body to the container holder through the first rotational body, thereby transmitting to the object the rotational motion according to the revolving direction while revolving the object.
