Step Screen Replaced By Headworks

In May 2008, Portland Water District installed 3 step screens in each of their 3 channels and in only 7 years of use, were facing maintenance & performance issues with the step screens. These screens were also affecting downstream processes. For e.g., the odor control system relied on an air intake via the screenings channel. In winter, the screenings falling back from the step screen would form a hardened log and block the screen face, thus affecting the intake to the odor system.

After conducting his due diligence, Scott selected the Mahr screen as he felt it was the best fit for his requirements. Scott did the equipment selection and engineering in-house, which gave him an in-depth understanding of the product and its unique features. In fact, after having had the unique advantage of seeing a Mahr screen operate right next to a Step screen for over a year, Scott is considering replacing the remaining 2 step screens with a multi rake screen. Scott had this to say about his decision to select a MAHR screen - “The MAHR screen is a very heavy duty and maintenance friendly screen and I am very impressed with its performance”.

The HEADWORKS MAHR BAR SCREEN brought a host of technical advantages to the table, along with the fact that it had several trouble free installations in the area operating for more than ten years which significantly bolstered the owner’s confidence. Also, the fact that a vast majority of the large wastewater plants in the U.S use the MAHR BAR SCREEN added to that sentiment.
