ATD – Anti Telescopic Devices

In membrane filtration systems wheel-like discs with built-in connections are normally used between spiral membrane elements, both to connect the permeate tubes and to prevent membrane-telescopic movement potentially caused by the hydraulic forces exerted on the feed end.

Wila ATDs benefits:

• Uniform stainless steel ATDs designed to prevent membrane-telescoping  
• Maximum flow area to maximize your production  
• Maximum opening design for efficient membrane cleaning  

In recent years we have optimised the design of our stainless steel ATDs and we have eliminated any need for welding, thus making the ATDs more uniform and, most importantly, more hygienic and easier to clean. Additionally, a more rounded and open design of the connection tube makes camera inspections, if needed, much easier than on other models on the market.
