Rotary Bar Screen
Rotary Bar Screen is a kind of special equipment for water treatment that continuously and automatically intercepts and removes various shapes of debris in the fluid.
Application Fields
· Urban sewage treatment plants, municipal sewage pipes, water plants and power plant cooling water, etc.
· Separation of debris at the water inlet can also be used in textile, fruit, aquatic products, papermaking, winemaking, slaughtering, tanning and other industries to carry out water washing or pre-treatment screening.
Advantages
· Have certain self-purification ability, smooth movement, and no noise.
· Compact structure, simple electrical control, easy to realize automation.
· Excellent corrosion resistance, low energy consumption and low noise.
· Continuous decontamination action, clean drainage and high separation efficiency.
