    • A settlement tank for use in a water treatment process. The settlement tank comprises a perimeter wall and a base to define a fluid holding region for holding fluid in the settlement tank. The settlement tank may comprise a scraper assembly comprising a scraper for scraping sludge from the base. A support connected to a central region of the base may comprise a mount rotatably mounting one end of the scraper to the support and positioned below an operational fluid level so as to be fully submerged during operation of the settlement tank. A drive mechanism for rotating the scraper assembly about the centre of the fluid holding region may be positioned outside the perimeter wall. An energy recovery device may be arranged to harness energy from fluid flow through an outlet formed in the perimeter wall. A launder trough via which fluid from the fluid holding region can exit the settlement tank may be constructed and arranged to define a walk way along which a person can walk. The launder trough may comprise a barrier wall with a plurality of holes below the operational fluid and scum level and through which fluid can flow to the launder trough.
    • 用于水处理工艺的沉淀池。 沉降槽包括周边壁和底座,以限定用于在沉降槽中保持流体的流体保持区域。 沉降槽可以包括刮刀组件,其包括用于从底部刮下污泥的刮刀。 连接到基座的中心区域的支撑件可以包括安装件,其将刮刀的一端可旋转地安装到支撑件并且定位在工作液面以下,以便在沉降槽的操作期间被完全浸没。 用于围绕流体保持区域的中心旋转刮刀组件的驱动机构可以定位在周边壁的外部。 可以设置能量回收装置,以利用流体流动通过形成在周边壁上的出口的能量。 可以构造和布置流体从流体保持区域离开沉降槽的流槽,以限定人行走的行进方式。 洗涤槽可以包括在操作流体和浮渣水平面下方具有多个孔的阻挡壁,并且流体可以通过该孔流到流槽。
