What preparations need to be done before filling the water treatment ceramsite filter material?

Before filling the water treatment ceramsite filter material, it is important to do the corresponding preparations, because filling the filter material often has certain requirements on the type, particle size and thickness of the filter material, which is also to ensure that the filter can be Preparatory work must be done to achieve a good effect of purifying water quality. So what preparations need to be done before filling the water treatment ceramsite filter material?

First, after the installation of the water distribution system is completed, first remove all the debris in the filter tank, and clear the water distribution holes and water distribution gaps, and use the backwash method to check whether the water distribution system meets the design requirements.

Carefully check the supporting materials of different particle sizes (different varieties in the three-layer filter material filter tank), and clean them in order from large to small according to their particle sizes in order to prepare for paving.

The ceramsite filter material for water treatment should be evenly laid on each layer of filter material. When the thickness of the filter material is reached, the filter material must be raked.

The thickness of the supporting material of each layer of water treatment ceramsite filter material should be accurate and uniform, and the surface should be scraped with a shovel or scraper to make it close to the horizontal plane, and the height should be consistent with the horizontal line of the pavement height symbol. After the supporting material with a particle size equal to or less than 2-4mm is laid, use the upper limit of the scouring strength of the filter to scour. Before scouring, the scouring intensity should be gradually reduced to achieve effective hydraulic grading and lift the light material to the surface of the supporting material. Drain again and scrape off light substances.

Water treatment ceramsite filter material filling work and all aspects, all details must not be sloppy, any error in any link may affect the use effect of water treatment ceramsite filter material in the future, so in order to successfully fill water treatment filter material, It is necessary to do the preparatory work before loading. Draw a horizontal line on the inner wall of the filter tank according to the top height of each layer of the supporting material and the filter material, as the pavement height symbol.
