Which Sewage Treatment Plants Are Suitable for Mechanical Bar Screens?

Hey, did you know? There's an unsung yet incredibly important piece of equipment in sewage treatment plants—the mechanical bar screen. It looks like a row of moving iron bars, specifically designed to intercept unwanted wastewater.

The first group of users is municipal sewage treatment plants

During rush hour every morning and evening, when toilet flushes, dishwashing drains, and shower wastewater pour into the municipal pipe network, mechanical bar screens are the first line of defense. They can easily intercept plastic bags, sanitary napkins, vegetable leaves, and even whole dead fish! Last year, after upgrading their equipment, a municipal sewage treatment plant removed three tons of garbage from its intake in a single day. Workers joked that it was "busier than a farmers' market."

The second group of users is food processing plants

Have you ever been to a cannery or slaughterhouse? Wastewater laden with meat scraps, fruit peels, and bones is too much for ordinary screens to handle. The mechanical bar screen's rake-like design scrapes away the sticky debris like a comb. A chocolate factory once shut down due to grease clogged pipes. After installing anti-tangling screens, repair costs dropped by 70%.

The third major hidden wastewater source is hospitals

Don't underestimate hospital laboratory wastewater; needles, gauze, and broken medicine bottles can get into it. After installing corrosion-resistant stainless steel screens at a tertiary hospital, even surgical sutures can be accurately intercepted, eliminating the need for cleaning staff to wear gloves when scooping out trash.

Special Note: If your factory processes oily or chemical wastewater, be sure to choose a model with a self-cleaning function, otherwise the screen will become stuck and "stop working." A coastal printing and dyeing factory suffered this loss last year, ultimately resolving the issue by replacing it with a model with high-pressure flushing.

In short, mechanical bar screens are generally suitable for any wastewater treatment involving solid impurities. However, the specific model you choose depends on the severity of your facility's wastewater—whether it's a daily routine or a full-scale banquet—the difference can be significant!
