What is the scaling of the fiber ball filter?
Pipe fouling in the fiber ball filter media means that the metal pipe is corroded, and the inner wall is rusted, resulting in a decrease in water delivery capacity. The cause of pipe fouling is complicated, mainly due to the interaction of water and metal in the fiber filter media. When the water content in the water is high, the pH is low, and the water is corrosive, the inner wall of the metal pipe is contacted. It is easy to form rust under the action of iron fine seedlings and sulfate reducing bacteria, and form rust on the wall tube. Most of the rust is tumor-like, and its outer layer is a shell composed of yellow hard iron oxide. The inner layer is black ferrous oxide and iron sulfide. The material is soft and mushy. It will be gently scraped with a knife. Rust odor.
Precautions for the construction of fiber ball filter
(1) It is necessary to pay attention to prohibiting the water pipe of the fiber ball filter filter from being built into the sewer channel or inspecting it, and it is not allowed to build a rainwater drain and a cable well.
(2) In the cold area, the exposed pipeline of the fiber ball filter should be inspected before the end of September each year, and the complete condition of the outer insulation layer should be checked.
(3) Check whether the foundation piles, brick piers and concrete piers of the overhead water pipes of the fiber ball filter filter have any decay, sinking or cracks.
(4) For the water pipes hoisted on the bridge, check whether the lifting components are loose or rusted.
(5) After the heavy rain, the fiber ball filter and the foam filter filter should be inspected in time for hanging grass, obstructing water flow or destroying the pipeline.
(6) Pipe trenches provided by other buildings. Where inspection wells are installed, they shall be opened periodically or inspected in person.
(7) All sites constructed near the pipeline should be listed as key inspection targets.
(8) There is no private self-contained water connection phenomenon.
