Disclosed is a rake-free thickening device including driving area. The device includes a feed assembly, a diversion assembly and a clean coal collection assembly. The clean coal collection assembly includes a driving area. The diversion assembly includes a central tank. Slime water passes through the feed assembly and flows with a medicament from an upper part of the central tank to a middle of the central tank, and then diffuses around. Bubbles carry the fine slime up after reacting. The driving zone drives the dispersed bubbles to a defoaming zone located in the middle of the central tank. The slime water in the central tank flows through the central tank after defoaming. With the continuously filling of slime water, the slime water above the central tank overflows the central tank to the clean coal collection assembly within the diversion and settlement area.

Embodiments of the present invention are directed to methods and systems for treating irrigation water by introducing a propagating electromagnetic field into the irrigation water as it flows through an irrigation system. The treatments described herein may have a variety of beneficial effects when applied to hydrophobic soils, including a significant increase in the percentage of the water that is maintained in the root zone of a given crop as plant-available water and the essential mineral, e.g. calcium and/or magnesium, uptake of that crop. The treatments described herein may also have beneficial effects when applied to hydrophilic soils, and particularly high salinity, hydrophilic soils, including a reduction in the soil salinity, including the amount of chlorates, within a root zone of a crop.

Systems and methods for desalinating a liquid are provided. A desalination system may include a main container and may be configured to provide at least one of an electric field or a magnetic field through the main container to control a distribution of ions in a liquid in the main container.

A waste liquid treating device includes a holding section that holds an adhesion plate, a vertically moving mechanism that moves the holding section vertically, and a peeling mechanism that peels off water-containing swarf from the adhesion plate held by the holding section. The peeling mechanism includes two air nozzles extending in parallel to each other in a horizontal direction with a spacing therebetween and including jet ports formed to face each other, a valve disposed in a piping providing communication between the two air nozzles and an air source, and a control unit that performs control of opening and closing of the valve and control of the vertically moving mechanism for moving the adhesion plate in the vertical direction in the spacing between the two air nozzles.
