摘要： A tine raking device includes a frame and a conveyor assembly supported on the frame. The conveyor assembly has a conveyor belt defining perforations sized to allow passage therethrough of granules of sand and to prevent passage therethrough of larger sized debris to be removed from a ground surface. Flexible tines extending outwardly from the conveyor belt. The tines are arranged in rows across a width of the conveyor belt. The rows each are longitudinally spaced from adjacent rows along the conveyor belt such that a generally unimpeded path is defined along an outer surface of the conveyor belt for debris to flow between adjacent tines along an associated row. The conveyor assembly includes a lower section for permitting the tines to contact and remove debris from a ground surface being cleaned, and an inclined section for lifting debris on the conveyor belt away from the ground surface being cleaned.

摘要： A method and apparatus is provided for inhibiting scaling in an electrodeionization system and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit by inhibiting precipitation of scale-forming metallic cations contained in the feed water and thereby increasing efficiencies of the electrodeionization system. Water to be purified is passed through an electrodeionization unit in which the flow in the diluting compartment is countercurrent to the flow in the concentrating compartment. This is to impede the migration of scale-forming metallic cations from the diluting compartment, through the cation exchange membrane, into the concentrating compartment and towards the concentrating compartment side of the anion exchange membrane, thereby preventing scale formation on the anion exchange membrane. The electrodeionization unit may be further modified by dividing the concentrating compartments into first and second compartments by a porous diaphragm or ion-conducting membrane. The porous diaphragm or ion-conducting membrane effectively eliminates convective transport of scale-forming metallic cations from the cation exchange membrane side of the concentrating compartment to the anion exchange membrane side of the concentrating compartment, thereby inhibiting scale formation on the anion exchange membrane.

摘要翻译： 提供了一种用于抑制电去离子系统中的结垢的方法和装置，更具体地，通过抑制进料水中包含的形成规模的金属阳离子的沉淀，增加对去电单元的给水中的硬度的耐受性，从而提高 电去离子系统。 待净化的水通过电去离子单元，其中稀释室中的流动与浓缩室中的流动逆流。 这是为了阻止鳞片形成金属阳离子从稀释室通过阳离子交换膜迁移到浓缩室中并朝向阴离子交换膜的浓缩室侧迁移，从而防止阴离子交换膜上的结垢形成。 可以通过多孔隔膜或离子传导膜将浓缩室分成第一和第二隔室来进一步修改电去离子单元。 多孔隔膜或离子导电膜有效地消除了形成规模的金属阳离子从浓缩室的阳离子交换膜侧到浓缩室的阴离子交换膜侧的对流传输，从而抑制阴离子交换膜上的结垢。

摘要： Electrodeionization methods and apparatus wherein ion exchange membranes are not utilized. Instead, ion exchange materials such as beads, fibers, etc., are disposed in alternating layers of anion exchange (AIX) materials and cation exchange (CIX) materials between opposite polarity electrodes. In a regeneration stage, a current is applied across the electrodes with water splitting occurring along at least one of the interfacial areas between neighboring AIX and CIX materials. The H+ and OH− ions formed via water splitting migrate in response to the electrical current and displace the salt ions in the respective AIX and CIX. The stack is flushed during the regeneration stage to remove the concentrated salt solution. During a deionization phase, the electrical current is terminated with influent fed to the stack for deionization. The salt ions in the influent are depleted via ion exchange as the influent contacts the AIX and CIX.
