Prefabricated filter plate manufacturer-Jiaozuo Haofei Environmental Protection Recommendation

Prefabricated filter plateIt is a key device in water treatment processes, playing a dual role in carrying the filter material layer for filtration and backwashing water (gas) distribution in the filter tank. The quality of filter plates, especially their flatness and accuracy, directly affects the filtered water quality, quantity, and long-term operational benefits of water and sewage plants. The traditional filter water distribution system has high resistance during filtration and backwashing, uneven water distribution, multiple stagnant water areas, easy compaction and mud accumulation of filter materials, and the loosening of the supporting layer due to local flushing intensity, resulting in adverse consequences such as sand leakage.

Product Parameters:

Adopting vertical steel mold casting, water cement ratio, and preparing materials such as fine stone and quartz sand.

The filter plate strictly follows the relevant standards, calculates the opening ratio according to the design requirements, embeds ABS engineering plastic embedded sleeves, and is equipped with double-layer bidirectional high-quality threaded steel bars.

Made of high-grade cement, standard fine stone and quartz sand, mechanically mixed, compacted and poured. The horizontal error per square meter on both sides of the filter plate is ± 1mm.

Product dimensions:

The standard specification is 980 × 980 × 100mm (length × width × height), which can be manufactured according to requirements.

The standard dosage of filter heads is 36 per square meter, and the arrangement quantity of filter heads is 49 per square meter, which can be manufactured according to requirements.

Prefabricated filter plateThere are strict requirements for installation in the filtration tank:

1. Construction shall be carried out according to the design drawings. The horizontal error of a single pool surface shall be greater than ± 2mm, and the elevation error of each grid filter shall not exceed ± 5mm;

2. The seam of the filter plate should be leak proof and able to withstand the pressure of flushing;

3. Before laying the filter plate, use a level to check that the elevation error of the supporting beam surface is less than ± 2mm;

4. The joint of the filter plate is embedded and filled with 903 polymer cement mortar. The joint is cured in a humid environment for three days and put into use after seven days;

5. During construction, attention should be paid to preventing mortar from leaking into the pool or sealing the filter head. After installation, the mortar on the filter surface should be cleaned thoroughly.
