Traveling water screens have come a long way since the first one was developed and sold more than 100 years ago. And we are proud to say that Evoqua has been there since the beginning (as part of the Link-Belt and Chain Belt companies). Let's take a brief look at the history of the traveling water screen.

 

A Brief History...

1874 – The Link-Belt Company formed by William Dana Ewart.

1892 – The Chain Belt Company formed by Christopher LeValley.

1895 – Link-Belt developed and sold the first traveling water screen.

1910 – Chain Belt sold their first traveling water screen.

1928 – The first dual flow traveling water screen was introduced.

1958 – Chain Belt in conjunction with Dr. Joseph D. Ristroph, developed the first capture and release fish handling method known as the “Ristroph Design" and was granted a patent for a “Fish Saving Apparatus”.

1973 – The “Ristroph Modified” Fish Basket with die-formed metal lip, was developed by Dr. Ian Fletcher and Royce Traveling Water Screen Co. (later acquired in 1988 by USFilter).

1993 – In conjunction with Dr. Fletcher we produced, the improved system known as the “Modified Ristroph/Fletcher Non-Metallic Fish Design Basket” was released.

2014 - Section 316(b) of the Clean Water Act was passed. The act requires all facilities that take in two million gallons of water per day to have some type of fish protection. Our screens are considered a BTA for complying with 316(b).


While we are on the topic of fish protection, have you ever wondered what a fish's journey through a traveling water screen looks like? Well, our new animated short can show you. Check out the video below!
