Stationary Water Screen FAQ

By Michael Stock



Traveling water screens are not always the one size fits all solution when it comes to water intake equipment. This was the case in one important area of our very own hometown power plant in Holland, Michigan.

In some applications a simpler piece of equipment, like a stationary water screen, can be used. We asked our intake experts a few questions about these water intake alternatives and here is what they had to say:


1. What materials are stationary water screens made of?

Stationary screens typically have a framework made from steel (painted or hot dip galvanized) or stainless steel (if used in salt water applications). The mesh inside of the screens is also made of stainless steel.


2. How does this compare to the materials traveling water screens are made of?

At Evoqua, our traveling water screens have non-metallic frames, making them 50% lighter than other screens. But like stationary screens, they have stainless steel mesh.


3. In which applications is it better to use stationary screens instead of traveling water screens? Why?

Stationary screens work best in applications where there is not a lot of debris that will need to be filtered out of the incoming water. Also in applications where the equipment upstream of the screen is not considered as critical as some to facility operations.


4. How do you clean stationary water screens?

It is important to note that stationary screens must be cleaned manually, so all debris has to be sprayed or scraped off by hand. In the case of the Holland Energy Park, each channel can be drained by utilizing our stop gates to keep the water out of each channel individually.
