Filter Plate Horizontal Installation

The filter plate is a key device in the water treatment process, which plays a double role in filter and backwash water distribution. The quality of the filter plate (especially the flatness and precision of the filter plate) is directly related to the water quality, water quantity and the long term benefit of the filtration of the water plant and sewage plant. The traditional filter filtration and reverse wash resistance water distribution system, water distribution is not uniform, dead zones, filter material easy to harden, mud, supporting layer of loose caused by local flushing strength at the same time, as well as the leakage on sand.

Filter plate installation accuracy is higher, it is important foundation is involving the filter beam the whole pool formation and buries the rivet head with stainless steel filter plate positioning accuracy, therefore, the filter horizontal beam leveling requirements, there must be configured a high standard of metal molds and skilled manufacturing technology, to ensure the smoothness of the filter beam, plane after leveling, install the filter plate again.

1. According to the requirements of the design drawings, the horizontal error of the individual pool surface is greater than or minus 2mm, and the elevation error of each grid filter is not greater than or minus 5mm;

2. The filter plate joints require no leakage, no leakage, can withstand flushing pressure;

3. Before the strainer is placed, the elevation value error of the supported beam surface is less than or minus 2mm with the water level.

4. The filter plate joints are embedded and filled with 903 polymer cement mortar, and the embedded seam is maintained in humid environment for three days and is put into use seven days later.

5. The mortar shall not leak into the tank or seal the filter head. After installation, the mortar shall be cleaned and cleaned.

Use the level of the level of the level of the water level, add the water detection to the water detection. The success or failure of the production and installation of the filter plate is directly related to the air - water backwash process. As compared with the traditional separate water flushing process, gas water backwash process increases the air recoil, it requires a single pool filter board face level error is not more than plus or minus 2 mm, each lattice filter the elevation error is not more than + / - 5 mm, only that it doesn't produce recoil uneven cluster result in sludge, affect the water quality and treatment effect.
