Ovivo USA，LLC已被授予其反向歧管设备（RMD）技术的专利。

相反的管汇设备(限制型心肌病)允许容易conversion from a downward RAS flow that travels under the tank floor/foundation to a new configuration where the RAS flow travels upward concentrically through the clarifier support column.

当以下情况下，应使用这种简单的低成本设备

• 坦克或地下不允许污泥线
• 坦克下方没有污泥线
• 现有的RAS线容量不足
• RAS线损坏或无法使用

新的RMD设计在竞标时给出了ovivo边缘，以转换为加拿大客户的现有澄清机组。RMD转换和从吸入式提升管切换到吸入头型Clarifiers，节省了数百万美元的现有罐结构修改。

In another project, the customer’s management issued an edict to abandon all underground piping. The RMD device allowed the RAS pipe to travel upwards out the top of the column and along the walkway. This allowed the existing clarifiers to be reused with minor modifications to the mechanism and no changes to the tank. CFD analyses conducted by a third party for this customer showed improved velocity profiles throughout the clarifier, which resulted in an improved effluent suspended solids.
