Ovivo®桥支持Clarifier

Ovivo®桥接支持的澄清器单元具有污泥去除系统,悬挂在跨越罐的结构桥。废水通过侧面进料管进入中心进料。饲料促进悬浮固体的絮凝,该固体流入澄清器,以在罐底部产生污泥毯。旋转耙臂可以配备犁刀片,螺旋叶片或抽吸管道以除去污泥,而脱脂装置收集表面的浮渣。

桥支撑的澄清器安装了从水流中连续去除大量固体。

该机制用于澄清和软化植物,以在化学处理后和砂过滤前除去沉淀物。它还用于浑浊或泥水的预沉淀。

  • Low maintenance
  • Trouble free installation
  • Long lasting design
  • 高污泥浓度
  • 高品质的污水
  • 低操作员注意

ovivo®桥接支持的澄清器(BSC)提供浓缩的生物固体和高质量的流出物。

桥接支持的澄清器可以在许多污泥收集配置中提供,以满足客户的特定需求或偏好。该机制可在传统的犁刀,螺旋耙刀片,吸管集管和吸管污泥收集设计中提供。

Ovivo circular clarifiers have been used in clarification for over 80 years, providing consistent and reliable results for numerous applications throughout the industry. The Ovivo cast-iron, oil lubricated drives are the best choice for long life, low maintenance, and dependable equipment in the harsh atmosphere of wastewater and industrial applications.

Ovivo的澄清器设计提供了无故障和快速安装。可用的各种选项和Ovivo的澄清专家将帮助您为特定应用选择合适的设备。

The bridge supported clarifier mechanism uses the fundamental principal of gravity separation of solids from liquid to produce a clarified overflow water and sludge. The sludge accumulated at the bottom of the clarifier is then scraped or sucked out and removed for further processing.

The clarifier mechanism is supported from the tank wall by a bridge or truss system which spans the tank. The drive is mounted to the supporting structure and the rotating clarifier mechanism (torque shaft, feedwell, rake arms) hang from the drive.

混合液通过侧面影响管道水平进入澄清器,并排放到絮凝饲料中。

絮凝饲料促进混合液悬浮固体的絮凝。它允许将流速逐渐重定向到澄清器中,并且絮凝物的沉降在罐的底部形成污泥毯。

ovivotype BSC bridge supported clarifier can be provided in numerous sludge collection configurations for tailoring to a customer’s specific needs or preferences. This mechanism is available in conventional plow blade, spiral rake blade, suction duct header and suction tube sludge collection designs.

Ovivo铸铁,油润滑驱动器是装备ped with bearings, worms and pinion mounted on a precisely machined surface. In every drive a high quality solid pinion maintains alignment and gives better resistance to bending and deflection under loads. Mating parts are machined to precise tolerances to assure precise fit and alignment. Every drive part is fully restrained (top and bottom) with no overhung loads. Main bearings are fully restrained into base. Worm gear reducer, single solid pinion, single solid worm / worm shaft and main gear all meet the latest AGMA (American Gear Manufacturers’ Association) standards.

每个驱动器配备有通过从蜗杆轴激活的过载控制装置。该驱动控制包括透明的塑料外壳和具有电动机电开关的环氧涂层铝结构的防风雨外壳。

Mechanisms are available in A36 steel, hot dip galvanized steel, 304 stainless steel and 316 stainless steel.

During winter in the Northern United States we experience icing problems with our clarifier’s conventional scum collection system and have to lock out the skimmer. If we don’t lock out the skimmer it is bent during heavy icing conditions. Is there a better solution?
Ovivo’s “full trough skimmer” is a full radius (the space between the feedwell and the scum baffle) scum trough and scum skimmer system. The skimmer system is neoprene curtain hanging from a rotating cantilever support beam. With two skimmer arms, the entire clarification surface between the feedwell and scum trough is swept into the radial scum trough twice per mechanism revolution. Because the neoprene wiper merely hangs from the cantilevered support, the skimmer will travel over any ice which has formed on the liquid surface.

我可以从澄清机驱动器中预期寿命是什么?
Ovivo’s clarifier drives typically last more than 30 years. We have seen some clarifiers running with drives that were more than 35 years old!

We are trying to decide on whether to use a column supported clarifier or a bridge supported clarifier. Is one better than the other?
仅基于成本,桥梁支持的澄清器在大约50英尺的直径和下方更经济。柱支持的澄清剂倾向于在40英尺直径和上方提供更好的成本。是的,在40到50英尺之间的直径之间存在重叠。网站,项目和过程特定条件可能是在选择两种类型的澄清器之间时需要考虑的因素。这应该用Ovivo或当地的Ovivo代表讨论。我们很乐意协助。
